Yes, it's exactly as LestaAZL has commented. The moulds you need for a pressurised bladder need to be incredibly strong (usually billet aluminium) in order to resist the deflection of the 'unbalanced' pressurised bladder. Therefore they tend to be very expensive to produce. An internal vacuum bag setup like this exerts equal pressure on the inside and outside of the mould, allowing much lighter, more cost effective composite moulds to be used.
Good point. Vacuum + plastic film= waste + money. You can make a thicker mould just by adding 3-4 layers of fiberglass or carbon fiber, hence achieving a stronger mould. I prefer the bladder anyways
this is the first time seeing your videos. I was designing composite parts in F1 for over 3 yrs of my 6yr stint and this offers the exact concepts and processes used in high level motorsport. Very nice.
There's a great deal of DIY composite videos on RUclips that often look like epoxy castings with a little bit of fiber in them... So we really appreciate what you guys are doing at Easy Comp, representing proper structural layup, in concise and useful little tutorials with slick production. Quality 🏆
Thanks very much. Yes, we try to show a range of ways of doing things. We will, in fact, be returning to some simpler and more entry-level topics over the next few videos but they'll always be showing a process that's used for a good reason, even if that reason is simply to avoid the need for complex tools or equipment. Stay tuned.

Please you do indeed, i've started with Fiberglass and Carbon Fiber just recently, but have been watching your videos for years and they showed that it is alot of work but no magic involved, i have quite a few molds already, the whole vacuuming equipment is coming together piece by piece, until then i am using a food vacuum pump with the tubes and the clothes bags, which both release awesomely haha
Wow man. I know im not going to he doing this any time soon due to financial reasons but when i do ill know whose videos to turn to. Superb explanations and very soothing to watch. Subbed.
meh not really. fiberglass parts are cheap as fuck. Cf is only slightly more expensive to work with. but it looks cool and people are easily fooled. so why not charge out the ass for it? the skills here are very basic. the tools very basic.

Thanks for the amazing content hope you keep making more videos. Wish there was videos many years ago or ways to learn more about composite molding so on. I remember it was hard to find much out there when it came to working with prepreg and doing mould making. When looked around was lack of anyone showing how to do prepreg was like it was a secret so most you would see was doing wet, other than Mclaren F1 or aircraft and few boats.
Hi, yes, that was our experience when we started out too. That's why, - as we acquired knowledge, figured processes out, or developed our own methods - we wanted to share them with others.
So there's a couple videos on older (~2014 ish) formula 1 turbocharger intercooler tubing and what they where doing was the smooth side of the part was on the inside of the tubing. I think this was to preserve airflow and avoid turbulence losses. I really wanted to know how they actually molded those parts?
on that particular part there appears to be no undercuts on the larger opening but the throat of the intake would have likely been separate part of the negative keyed into the rest of the negative part. The process would be generally the same as creating the first mold for a standard part as seen in Easy Composites "Fibreglass/FRP Split-Mould Making Guide" or "How to Make a Prepreg Carbon Fibre Mould", except instead of having a split on the outer layer you would split the internal buck to easily remove it. For more complicated internal geometry you would have to include draft angles in the internal buck in order to ease removal as seen in "Making a Carbon Fibre Bike Frame" @32:30 with removing the inserts for the pass through on the frame.
Hi Christian, I'd agree with what Andrew says.The best process for parts that are 'smooth on the inside' would either be a made tool (if the part could be removed from the without becoming stuck) or it could be a male tool in more than one part, i.e. a split male tool, this would be common, or - for really complex shapes like induction shapes with multiple turns, then you could even use a sacrificial core. These wash-out or melt-out cores are a whole complex subject in their own right but in general they are made from a material that can be dissolved with water or melted out (lots to consider in terms of cure temp of the prepreg vs melt temp of the core) which is either cast (into a mould) or CNC machined.

6:31 at glider fuselagebuilding we use fishing line which goes in a zick-zack (Z-shape; x-shape) over the mould surface to hold down the wet carbon fibres.

It's really very difficult to make something like this using a resin infusion process. Nothing is impossible but the practicalities of dealing with dry fabric and then handling the infusion consumables, it just makes it too difficult.
@@easycompositestv indeed it is. The resin needs heated and degassed for a start. The material needs an activator and heat, to create a pre-formed shape. And then the resin needs injected with compressed air pushing it in, with vacuum at the other side helping draw the heated resin to every crevice in the pre-form. That's the "vague" theory used by aerospace to make resin infused carbon parts 👍 (I worked on autoclaves in this way)
@@E9JMX The only things that I find wrong with your reply is #1. The A+B epoxy creates its own heat to cure. #2. You only need vacuum to draw the epoxy into the material. #3. Adding compressed air would add air to the mix. Keep in mind I used to do these processes when making carbon fiber prosthetics. Adding to the fact that we both understand manufacturing, our products might require different processes. Just throwing my two cents in.
Hi guys...thanks for all the tutorials. Actually i was looking to make carbon fibre wheels ...could you guys make a tutorial for that too if possible? Also do you guys ship to India? I really wanted that chemical release agent
Hi Arsh, thanks for your comments. I'm not sure we'll make a video specifically about making carbon fibre wheels because it's unlikely that anyone at the learning stage of the their composites is going to take-on making carbon fibre wheels. However, the process would essentially be a combination of what you see in this video and in our bike frame video, with a lot of extra complexity and really critical calculations and knowledge for safety.
Very good informative video. Makes me want to start my own projects. What would be the easiest car part to start making? Interior trim, outer panels, induction etc etc...
Hi Kevin, I would say that modest sized external components are a good starting point. Interior trim pieces tend to be rather fiddly and have added complexities of mounting lugs etc. If you're thinking of using prepregs, such as shown in this video, then induction components could be a good place to start, or some exterior details like scoops or vents.
Koenigsegg* but yeah it's stupidly hard. And koenigsegg makes sure all the weaves line up then sand down the outer to a perfect matte finish. So if it takes two hours to make this tube for a normal person, you can look at about four to six for koenigsegg.
Hi Chris, the split-mould we used in this video is a prepreg carbon fibre tool. The patterns (for the two halves) were CNC machined from epoxy tooling board like in ruclips.net/video/CWAvo8DIZ9s/видео.html and then the mould halves made from made from XT135 carbon fibre tooling prepreg like in ruclips.net/video/k4GdAuNji5g/видео.html. There are other solutions for making high temperature moulds, such as a hand layup process using high temperature epoxy tooling gelcoat, resin and paste which you can find out about in this tutorial (on our website) www.easycomposites.co.uk/learning/hand-laminating-a-high-temperature-epoxy-mould
Well, of course that's right Roger; advanced carbon fibre composites are definitely not a potential rival for mass produced forms where weight is not critical.
Can you guys also make a video about the stiffness and flexibility of carbon parts? Tensile strength, bending torsion etc. according to the number of different layers and production types. That might be very useful information for us before we start production. By the way, great quality content, thank you
Yes, we're planning this right now. You probably noticed we have our universal test rig so we can perform any kind of tests like this. We'll do something comparing different materials and forms quite soon.
Those bags can also be re-used as a cost-saving measure. I use them about 20 times when using pre-preg at 400 degrees Fahrenheit for 30 minutes. You can seal one end of the bag with a thermal sealer. The high temp tape used to seal the bags can also be reused at about the same rate. I should keep in mind that our setups are a bit different than yours. The general idea is still the same.
Hi Tony, nice advice. I posted (a little further down) too about the possibility of reusuing consumables. We've never found it practical to re-use tape unless it can be left in situ but I guess that's what you mean. Thanks for the post.
More great instruction! Thank you! At risk of sounding ungrateful... Any chance you will show how you made the mould for that tube? Please keep the videos coming!
Check the bike frame video - looks to be the same process using tooling prepreg (it has an integral black gel coat. Easy Composites high temp epoxy gel coat is grey, so this is not a wet lay carbon mould.)
Hi Vinn, yes, as the others have posted it's a prepreg carbon fibre tool. The patterns (for the two halves) were CNC machined from epoxy tooling board like in ruclips.net/video/CWAvo8DIZ9s/видео.html and then the mould halves made from made from XT135 tooling prepreg like in ruclips.net/video/k4GdAuNji5g/видео.html
I'm very keen on his stuff now. Almost as accessible as fiberglass for the previous generation. I have a similar question to Jason's. Can some sort of balloon be used in an internal mould? Not many unlikes but it does seem you may be ruining someone's business model, that has no barrier to entry. It seems that's now in the design itself if we want to be productive so we can't just copy someone's steel or alloy product and make any money like that. I think that's just progress. I think this is great. Just looking at what else is around before I subscribe. I think you might be a first mover here. Nice timing, while so many are stuck at home.
The moulds you need for a pressurised bladder need to be incredibly strong (usually billet aluminium) in order to resist the deflection of the 'unbalanced' pressurised bladder. Therefore they tend to be very expensive to produce. An internal vacuum bag setup like this exerts equal pressure on the inside and outside of the mould, allowing much lighter, more cost effective composite moulds to be used.
We probably won't make a video on this exact mould but we have covered the process (pretty-much) in two of our other videos. The split-mould we used in this video is a prepreg carbon fibre tool. The patterns (for the two halves) were CNC machined from epoxy tooling board like in ruclips.net/video/CWAvo8DIZ9s/видео.html and then the mould halves made from made from XT135 carbon 10:00 28/04/2020fibre tooling prepreg like in ruclips.net/video/k4GdAuNji5g/видео.html.

Could I ask that you maybe do a video on making a 1:32 scale model car, perhaps use a scale die-cast car as the basis of the mold, I have seen a few resin cast cars but after watching video it dawned on me that carbon fibre in single layer coukd be mush more durable as a slot car and I think a lot lighter than resin cast

Is there a reason to use vac instead of just pressurizing a bladder inside the mould?
In vac, the atmospheric pressure push the mold together. When bladder tries to open the mold, so you would need stronger mold to hold
@@LestaAZL I was wondering this same exact thing. Thanks for the logical response.

Thanks Justin, we appreciate the support. Keeps us going with them.
I can and will make anything and everything from carbon fibre.
This is awesome! I’m still trying to do the basics
This reminds me of my days working on the B-2 bomber. Days I'd rather forget. lol
Very good informative video. Makes me want to start my own projects. What would be the easiest car part to start making? Interior trim, outer panels, induction etc etc...
Hi Kevin, I would say that modest sized external components are a good starting point. Interior trim pieces tend to be rather fiddly and have added complexities of mounting lugs etc. If you're thinking of using prepregs, such as shown in this video, then induction components could be a good place to start, or some exterior details like scoops or vents.
now we know how hard can it be, when you want to make a Koenigzegg
For sure, this is labour intensive work!
Koenigsegg* but yeah it's stupidly hard. And koenigsegg makes sure all the weaves line up then sand down the outer to a perfect matte finish. So if it takes two hours to make this tube for a normal person, you can look at about four to six for koenigsegg.
Brilliant as usual guys
Thank you! Appreciated.
cost of carbon fiber pieces: 10%, cost of materials.... 90% PITA tax
Great video and yeah it's good to hear that you are back with some interesting projects
Thank you Saiyashwanth, I'm pleased you find this interesting.
This looks exhausting and expensive.
Exactly why carbon parts are expensive
nice material
Life is good.
Bro we’re able to build complex carbon Fiber parts so easy… LIFE IS GOOD.
Your videos are excellent.
Glad you like them!
That is one sexy end product. Wow.
Thanks for the comment, glad you enjoyed the end result!
I'm so glad I found u guys
I would love to see a cideo of how you made the mold.
Love your vids
Hi Chris, the split-mould we used in this video is a prepreg carbon fibre tool. The patterns (for the two halves) were CNC machined from epoxy tooling board like in ruclips.net/video/CWAvo8DIZ9s/видео.html and then the mould halves made from made from XT135 carbon fibre tooling prepreg like in ruclips.net/video/k4GdAuNji5g/видео.html. There are other solutions for making high temperature moulds, such as a hand layup process using high temperature epoxy tooling gelcoat, resin and paste which you can find out about in this tutorial (on our website) www.easycomposites.co.uk/learning/hand-laminating-a-high-temperature-epoxy-mould
I love watching a Pro creating perfection
This channel make me want to make hypercar company.
Amazing video.
Thanks a lot; maybe you should go for it!
Your videos are always top notch 👌 thank you for it
Thanks, we appreciate you comments and support :)
This is so labour intensive it will never replace traditional metal methods except for absolutely weight critical applications.
Well, of course that's right Roger; advanced carbon fibre composites are definitely not a potential rival for mass produced forms where weight is not critical.
Never is a long time and there are always smart people looking to save a it of it.
this is extremely satisfying.
I don't know why I'm watching this. But I enjoyed it.
What a great tutorial / demo!
Wow, I’ve been wondering how to do this for such a long time. This video is content gold!!
Thanks a lot, glad you enjoyed it and it helped you to understand the process.
EASY COMPOSITES Ltd™ My new "drug of choice"
these videos are really fun
Haha, then you think like us!
Can you guys also make a video about the stiffness and flexibility of carbon parts? Tensile strength, bending torsion etc. according to the number of different layers and production types. That might be very useful information for us before we start production. By the way, great quality content, thank you
Yes, we're planning this right now. You probably noticed we have our universal test rig so we can perform any kind of tests like this. We'll do something comparing different materials and forms quite soon.
@@easycompositestv Perfect, i am looking forward to your test datas
Those bags can also be re-used as a cost-saving measure. I use them about 20 times when using pre-preg at 400 degrees Fahrenheit for 30 minutes. You can seal one end of the bag with a thermal sealer. The high temp tape used to seal the bags can also be reused at about the same rate. I should keep in mind that our setups are a bit different than yours. The general idea is still the same.
Hi Tony, nice advice. I posted (a little further down) too about the possibility of reusuing consumables. We've never found it practical to re-use tape unless it can be left in situ but I guess that's what you mean. Thanks for the post.
Five Star Tutorials !!!! ... THANK YOU
Thanks Shawn, glad you liked it.
More great instruction! Thank you! At risk of sounding ungrateful... Any chance you will show how you made the mould for that tube? Please keep the videos coming!
Yes please I second that.
Check the bike frame video - looks to be the same process using tooling prepreg (it has an integral black gel coat. Easy Composites high temp epoxy gel coat is grey, so this is not a wet lay carbon mould.)
Hi Vinn, yes, as the others have posted it's a prepreg carbon fibre tool. The patterns (for the two halves) were CNC machined from epoxy tooling board like in ruclips.net/video/CWAvo8DIZ9s/видео.html and then the mould halves made from made from XT135 tooling prepreg like in ruclips.net/video/k4GdAuNji5g/видео.html
I'm very keen on his stuff now. Almost as accessible as fiberglass for the previous generation. I have a similar question to Jason's. Can some sort of balloon be used in an internal mould?
Not many unlikes but it does seem you may be ruining someone's business model, that has no barrier to entry. It seems that's now in the design itself if we want to be productive so we can't just copy someone's steel or alloy product and make any money like that. I think that's just progress. I think this is great. Just looking at what else is around before I subscribe. I think you might be a first mover here. Nice timing, while so many are stuck at home.
The moulds you need for a pressurised bladder need to be incredibly strong (usually billet aluminium) in order to resist the deflection of the 'unbalanced' pressurised bladder. Therefore they tend to be very expensive to produce. An internal vacuum bag setup like this exerts equal pressure on the inside and outside of the mould, allowing much lighter, more cost effective composite moulds to be used.
that mtn bike is some serious work.
It was an excellent work, thanks for sharing us those valuable info's in details 👍
You're very welcome, glad you liked it.
Great video ! How about doing another one on making the mold ? Looks like a really nice mold.
We probably won't make a video on this exact mould but we have covered the process (pretty-much) in two of our other videos. The split-mould we used in this video is a prepreg carbon fibre tool. The patterns (for the two halves) were CNC machined from epoxy tooling board like in ruclips.net/video/CWAvo8DIZ9s/видео.html and then the mould halves made from made from XT135 carbon 10:00 28/04/2020fibre tooling prepreg like in ruclips.net/video/k4GdAuNji5g/видео.html.

Well done guys. I learned and am greatful. Keep them coming.
Thanks a lot, we'll do our best to keep them coming.
Could I ask that you maybe do a video on making a 1:32 scale model car, perhaps use a scale die-cast car as the basis of the mold, I have seen a few resin cast cars but after watching video it dawned on me that carbon fibre in single layer coukd be mush more durable as a slot car and I think a lot lighter than resin cast
Wow just wow. Who the hell knew it was something you just cut like a fabric
