I smiled when I realised what that little room at the back of your workshop is.. a sort of poor-mans autoclave (oven, really, no above atmospheric pressure).. After installing the giant autoclaves at Premium Aerotek in Germany, my Dad went on to work with the teams doing exactly what you're doing - but on a giant scale - building carbon fibre Airbus airframes (A350 XWB).. laying out, bagging etc. The only difference is their layouts went on 70ft long, 22ft wide skids to be dragged into the giant 25m x 8m autoclave, making it expensive and annoying if the bagging failed! So thanks for surfacing some fond memories :)
Hey just a head up from another DIY Carbon Guy, since you infuse upwards with the resin below the part look at the MTI Valves for the resin intake line. They will keep the part under vacuum pressure and you wont have to bother regulating resin flow to avoid pooling, and the parts wont lose as much vacuum when the resin inlet line is opened to ambient air.
Holy sh!t there are some serious "tricks of the trade" being given away here, this is amazing! Thanks for sharing! 👍
Makes me want to try my hand at it! Also love to watch time lapses, but i have a question for the ballooning of epoxy, what if you were to lay the part flat? Would that not eliminate the gravity issue?
Truely impressive, AJ! Thanks for taking the time to upload.
Fantastic instructional content! Do you think you could do a video of the process of making the mold for this hood or any other large bodywork?
I will eventually.
@@ajhartmanaero I need a crowl hood carbon fiber for a 1993 GMC Sierra how much do you charge or how do you 21:34 suggest so I can make it
@@ajhartmanaerodo you do work for others? If so I have some items for a drag car I would love to see if you could help. Thanks either way
If I had this level of skill and access to all of these tools and materials, I'd probably be driving a full carbon fibre Acura TL 😂
Facts
You and I both lol cf TL with cf wheels too 😂😂
Amazing job! Just a question: Why don’t put in vacuum bagging for a perfect bond of the two parts in the end? Thanks, you are great!
No hard rule against it. But generally vaccum bagging is needed for lamination with minimal epoxy (weight savings). Clamps do a good job for glueing parts together.
Using vacuum bags for glueing parts requires more effort, creates extra mess and a ton of wastage for no additional strength or weight savings!
Then again, what do I know 🤣
For intact result
Have you ever made carbon fiber, inner fender wells for like an old Chevelle?
awesome video, i would of liked to see the hood latch stuff added and maybe some more of the "side" structure. but this was awesome. any final product footage ?
Lovely finish, thought the seem line between the two halves would be more obvious, but that is great looking bonnett
Love the content! Quick technical question… I’m not sure if this has been answered somewhere already but figured I’d ask. When it comes to the rigidity portion of carbon fiber panels, I recall years ago that some manufacturers would use aluminum/titanium rods as support and to add rigidity. Would doing something like that be beneficial or would it be best to just sticking with all carbon fiber with just carbon fiber reinforcement in those high stress areas? Thank you in advance!
Don't know if you still need an answer to this question, but it entirely dpeends on why you'd need reinforcement.
If you're looking for rigidity as you said, you will need some sort of brace that would span your contact points which you want to remain rigid. More layers of carbon will not offer this rigidity. Watch any video of someone lifting a fully carbon hood, it bends, carbon is incredibly flexible along it's flat axis, even with thick layers of epoxy.
What kind of clear coat are you using in the mold prior to Layup? Duratek? By the way your videos are THE BEST composite videos on RUclips please don’t ever stop making them
Is the clear coat you spray in the outer mould a urethane clear coat? Maybe a gel coat clear? And it becomes part of the final part? I couldn’t tell if it was still tacky when laying the first layer. Great video though!
Wow, that was great. Was that 2k automotive clear you sprayed? I have a autobody background, so I’m big on prep. The clear coat doesn’t have to be prep or scuffed for the epoxy/cf to stick, after it was cured? Have you ever used clear gel coat or is that what it is. Great video man.
I believe in mold clear by duratec
@@rohanpuri1989 what? I have the same question about what was used for that coat
I have the same question. If it is gelcoat I dought it is UV resistant. Would be curious what clear was used.
@@danielh4759 pretty sure its gonna be sunshield by duratec
Curious to know the answer to this as well. Just started my Composites class at DATC
Brilliant video! Thanks for taking the time to make it!
Would you mind if I asked what knife you are using the cut your carbon as it seems almost effortless in comparison to scissors?
yep
Really awesome work, I would love to see your moulding process
Keep up the good work
How do you match the weve of the carbon waying laying the two halves over eaach other?
Top secret. But have been thinking of doing a video on how I do it.
@@ajhartmanaero please do!
@@ajhartmanaero yes!
Awesome! What Carbon thickness do you use for hoods?
7
Can you make me a custom carbon fiber hood & trunk?
Seen a few of your videos and blown away by the work you guys do!!!
Would love to know if you guys do custom carbon fiber hoods for random cars (ones not already on your website)?
We do not. Wayyyy to time consuming to do the molds.
Again a great video! What spray tack do you use? Thanks! 🤙🤙🤙
Awesome stuff! What was the final weight of the hood pls? And how much heavier would have been if the bottom part - the reinforcement was of fiberglass?
Iv done a few just covering the bonnet with carbon fibre then clear coat UV finish. Best way is resin base coat wait till tacky then roll from one side to the other. Don’t try the spray glue way
Following your work from Japan Congratulations!
My favourite youtube channel, so much good infos to work with composite. Great job🤝
GREAT VIDEO AND EDUCATION. I NEED TO START SIMPLE AT FIRST. THEN BUILD FROM THERE, THANKS FOR SHARING I LEARNED SO MUCH!!!!!
IM GLAD YOU LIKED THIS VIDEO ENOUGH TO PUT THIS ALL IN CAPS LOCK
So dope, I love love love the process
3:37 at 0.5 speed got me 💀💀🤣🤣
That looks nice. I have a question I bought a carbon fiber hood but the holes for it to get bolted to the car are closer and don't match with the cars hinge
Hi, really nice job! A question, what kind of glue do you use to weld the both parts together?
What's the weight difference between carbon fiber and the oem (metal) one?
Thanks for all these videos you published. I have noted that in making the hood in some cases you apply a clear coat on a mould before putting the first carbon layer for infusion and in some cases you dont. Is it really neccessery to apply clear coat? Does the applying a clear coat makes the outside surface more shine or? Thank you in advance for your answer!
I use to make carbon fiber bonnet 15-20 years ago. there wasnt many people doing it back then. i used 1.5m roll widths so you dont see joins
Love to see your work but it seems like there are no videos where you instruct on the layout.
Love your videos and quality. My question is what is the blue tape you use to keep the weave from getting messed up when cutting the carbon and also when making a Chevron seam in the middle of the hood?
blue tape is just blue tape. I did a video on how I do the center weave.
Great series. What glue do you use to bond the hood components together. I believe some people use methylmethatrolate
As usual the video was great. Could you break down what you have in you vest?
Several people commented on my vest. Might be worth a video soon.
Do you have a video on the mold process? I think that would be a really dope and informative one
Yes. A few videos ago we did a mold.
How long does it take you to make just one hood? And appoximatley how much are you paying for all the materials. Im looking to make a boat in future out of csrbon fiber and i would like to have a good idea of the time and cost.
I have a plastic boat that is made with upper/lower clamshell style pieces.
Id like to split it and use it as a mold to make a CF version.
Im wondering if i could do it for under a grand. I have service truck worth of tools but no vac or other related stuff.
I use the boat for river adventures and its setup to row. Id want to incorperate some keel sheilding for landing and dragging/rock protection. I currently use hdpe patches that take hours to make.
Boat is 10'x4'x36" & weighs about 140lbs from factory with foam blocks inside. Wondering where it would sit if made from CF.
Wow I didn't know clear coating prior laying up was possible!
may i know what product you use to demold? so resin wont stick to the mold or in the other video to the glass? also i see you used 2 pieces... is the line between both sheets visible?
thanks
superb. Can u please tell exactly what type of carbon fiber you used
That’s fantastic! Have you got a link to the clear coat you use to spray into the mould before the carbon goes in? I alway post-lacquer my stuff but this looks much better!
Clear coat weighs more
Did you ever figure it out? I’m also looking to buy lol
Nice but is there a way to get a bigger width so you don’t have to have the seam in the middle of the hood?
Yes. There is 60" wide carbon.
A.J what kind of spray do you use GeForce saying down the carbon fiber? I would like to try this process myself. Thank you
love the videos. Im going to attempt a hood for car soon. Do you need hood pins if Im using a factory latch. And do you have any recommendations on a vacuum pump. I have one from harbor freight. Not sure if its adequate. Thanks again
What's the surface of your workbench if you don't mind me asking? I'm making a table to cut my fabric on and have been trying to find a material I can use that's large enough
Thanks for the great video!
So you basically only have two layers?
Do you think it would survive at high hood temperatures?
Never an issue yet
There is a significant price difference between a fully CF hood and a single layer CF over a fiberglass or ABS skeleton
They aren’t marked up at all
Thanks for sharing, seems difficult, Nice work
Amazing that so little fiber and resin can create a strong piece
What carbon fiber fabric do you use. it looks like it dosent frey at all
now this is the real carbon fibre making... not the wrap, paste and go kind. i feel like I want to order from this guy, but Iam far across the ocean in Malaysia.
just subbed! had a question. How did you go about making your molds for the carbon fiber?
Stay tuned. Editing a mold video right now and will be out soon. But simply put the molds are orange tooling gelcoat and fiberglass.
very nice work! can you sent me a link were i can buy the carbon fiber roles?
How does your resin stood up for 40mins+? Doesn't it dry quick? What's your method for your resin to stay dense for quite a time?
I need a carbon fiber hood for my 01 firebird. I want to try this so bad
What product do you use to bond the two together please?
So cool to see stuff like this. Whats the weight difference between this and the stock hood?
This was 11lbs. Oem aluminum is 23 and oem steel is 36 or there about if I remember right
what is the purpose of that white “core” stuff?
wondering if isnt better to use the same resin instead of panel bond to glue both parts together.
This is the 2nd video of yours I’ve watched (subscribed now), and I’m curious of something. Wouldn’t you want the first layer to be as close to a single sheet as possible so you don’t have split lines or potentially mismatched strand orientation to the customer facing “show” side. I understand that some shapes make this impossible (likely). Just my curiosity.
Yeah. There is 60” wide carbon if you wanted to use that.
what was the little spray can you used just spray glue or something else, also it said on screen that you used clear coat i thought you had to use gel coat did you use any release stuff as well or just straight up clear coat onto bare mold
first video of your's i watched and i subscribed now excelent work. But i have a question what is that component that you use to bond two pieces together
thanks.
3m panel bond
You make it look so easy. When if most definitely isn’t!
What are the particularly difficult parts? I actually want to know. Planning an attempt for the near future for one of my cars.
I want to learn how to make my own carbon fiber bonnet (hood) am i wrong by saying i can do it in reverse to the way you am doing it to use the outer skin or would i just completely mess it up doing it that way ?
Would you be willing to share your strategy for making pleats in the butyl tape, in regard to the frequency and length of them versus the amount of bagging material? Or do you just sort of eyeball it?
On something this relatively flat, just a few random ones roughly eyeballed. More pleats is always better than not enough.
hello very good job!
question with what do you cut the carbon can you show the tool you use?
THANKS
Dremil if gone off or sharpened scissor when in cloth
I hope the speed of those cars justifies their obnoxious spoilers
It does.
Much respect - craftsmanship ! Make any parts for 996's ?
What would be a reasonable price for one like this I have a 2013 Subaru BRZ limited
Very very neat work
I loved this and the result was amazing
Tell me pleas at 18:47 what kind of glue you used??
Could you make a video of all the products you use and why 🙏🏽 please ❤
What is your "clear coat" ?? Is it resin OR a paint? Thanks form New Zealand. Love watching your vids. Thanks for sharing. 10/10
Clear coat is a spray paint to make the surface look shinny and clear
15:33 would it be better if the part is horizontal as opposed to vertical so you dont have to fight gravity?.. love the content
I used to do large stuff flat and never noticed a difference. I always try to infuse uphil simply cause it’s easier for air to float up ahead of the resin front.
hello good day, what core material did you use in the hood and how thick is it? thank you.
It looks simple, but it's expensive.
looks good
Is this more an diy set up or mass manufacturing be similar but just a better set up for cost / time saving for maximum profit ?
Awesome!!!
How do you get giant rolls of carbon fiber fabric?
that was impressive!
Nice video nice to see how Something is builded.
But for what you wear this vest ??
Best wishes from Germany
It holds all my tools.
OK that make Sense 😊
What's the strongest resin to that bonds to carbon fiber and can stand the stresses and temperatures placed on it in the automotive industry?
What type of clear coat did you apply?
Great video as always
no lung protection for carbon fiber dust, for the beginning???
Awesome! Would the resin flow better if the part were horizontal as opposed to vertical?
the orientation is not critical. the vacuum sucks the resin in every direction and is the driving force.
I’m confused what did you put before the clear coat ? To make it come off with the hood ?
really nice! Can you make car door which have window glass frame??
first time seeing, that clearcoat is applied as first one and ther tride...
Why not clearcoating final part?
What kind of tape are you using in the center of the outer shell's first layer?
Thinking about it I think my eg civics "carbon fiber" hood is a fiber glass hood with the carbon fiber on top lol
Most likely it is. I did a video a few years ago showing how to tell the difference.
I ain't to mad it came with the car and it's chipped and cracked so I wanna do something with it I've seen people doing stuff with chopped carbon fiber and gilding foil
Looks awesome 😊
What is put on the bags used for pulling vacuum? I can never find anything that deals to the bag
hi, did you making Mitsubishi EVO 10 hood?? and postage to Malaysia Kuala Lumpur. i to buy.
Man, you are good. Do you make a hood for the 2018 Range Rover SVR?
I don’t. Sorry.
Beautiful results.
Slick technique! Do you do E82 135i hoods…? Nice job…💪🏻🏁
Thanks. I don’t have a mold for E82’s so can’t do those.
@@ajhartmanaero Oh I see, maybe something to think about in the future. Lot of guys out there that would buy your hood & parts. For the E92 as well…👌🏻🏁
Gotta ask, why the tactical vest?
So what's your price and do you do foxbody mustang hoods
