PERFECT MOULD. Carbon Fibre Mold. Fuel Flap with Aluminium Metal Powder [PREPREG] (Fiber)

- CARBON (FIBRE) Fuel/Gas Flap Mould Making Using Aluminium Metal Powder to reach higher temperatures! PREPREG
Here iv taken a standard polyester gel coat capable of being post cured at 90 degrees Celsius before warping. By adding Aluminium powder to the mix it can now withstand up 135 Degrees!
Benefits are huge compared to laying up an epoxy mould, main points are the time saved and all round easier to make.

![How To Repair Damaged Carbon Fibre Mould to New PERFECT Mould. [CARBON FIBER REPAIR]](/img/1.gif)
Just me experimenting and filming the process... I'm adding metal powder to increase the temperature the mould can be taken to. Really pleased with these results 😎
Could you explain the theory why adding metallic powder would enhance the thermal performance of the resin.
@@lorenslin1968 This is the description from the manufacturer
"Aluminium powder is very frequently added to resins and gelcoats in order to improve their dimensional stability, particularly for use at elevated temperatures."
Also I tried a mould without metal powder and it warped, but fine with it.
Thanks
bro. you should let us see how you do the full job. we need your knowledge. thanks!
@@ankualex what more do you want to see?
@@CarbonWorkshops did you add the aluminum powder only to the gelcoat or also to the tooling resin?
Cool Video mate😎 Like your alternative ways to make it work. And as we see, great results!
My new favorite channel ! 😊
Super ton travail...j'adore le mélange avec la poudre pour la résistance du gelcoat 👍
Hello, cool videos, I'd like to make a lighter (carbon fiber) cabin air filter tray for my e46 bmw track car. What do you recommend using or doing to make a mold? I'm a newbie and would like to do the easy way like on one of your videos. Thanks!
Nice work
I'm guessing that all the temps shown are in Celsius
What is the significance of the metal powder?
Thanks for these videos, can you do a mould making tutorial?
Iv made lots of them already 👍
Is there a particular reason why you used the GT600 tooling gelcoat from eastcoastfibreglass versus the UG-1 tooling gelcoat from easycomposites?
Also, isn't the service temperature for the Unimold system resins (coupling and tooling resin) still limited to 90C? Or does the fiberglass reinforcement support it enough to go to the higher temperatures?
I guess time and multiple uses will tell whether this type of mold will be durable, but this is super interesting for low run prepreg parts.
Hi, Iv used ug1 and result were not great with prepeg I think because it's vinyester based. But using polyester mixed with aluminium powder works great for me.
And yes uni mould is meant to be max 90deg but I think mainly its because the ug1 gelcoat will soften. Iv not noticed any shrinkage and warping taking it 135.
Have you ever tried to put some aluminium powder into the tooling resin as well?
have you try use aluminium powder direct on carbon fiber fabric and melt it instead of use resin.
will met the carbon filaments?
Not tried that. Could be interesting
Nice. is the "GC50 Polyester Gelcoat" from easy composites compatible with this process? Also Is this a fuel flap replacement or just a cover? thanks!
No not for the process I used which was prepreg. GC50 is good for infusion or wet hand layup
WoW 👍
Первый слой синий это типа самодельный гелькоут
Can you use any colour polyester gelcoat with the alloy powder? I've got plenty of white polyester grlcoat.
I think so yes 🤟
@@CarbonWorkshops cheers mate
why did you mix aluminium powder into the gelcoat?
To increase the temperature the mould can be cured to
Hello, great work! Where can I purchase the yellow filet wax?
Any composite supplier should have it. Or ebay/amazon
Thank you!
Beautiful videos. I would be interested in how to paint the carbon with transparent paint, so that the 3k or 12k model can be seen under the paint...see parts of the beast components.
You put pearl or candy in the clearcoat.
I would experiment with an airbrush first to get the ratios right on a piece of scrap.
is the oven actually needed?
Yes because the prepreg carbon only cures at high temperature. Some other carbon fibre methods would not require a oven.
can you use any polyester gelcoat with the alloy powder ? are you using prepreg carbon to make the part?
Yes you can, and yes prepeg to make the parts
@@CarbonWorkshops ive worked with fibreglass for over 25 years. i know about getting the air out etc. just looking for ways to make moulds for prepreg oven use other than epoxy as its getting too expensive to keep using epoxy etc
@@garrybull4165 my apologies, I deleted last reply I though it was for different video. Yes I can't see why you couldn't go large with this method!
@@CarbonWorkshops thanks. i'll have to give it a go at some point.
was the resin you used polyester?
Hi, thanks for the informative content, some of the best on RUclips. Could I ask though why you chose this method over alternatives like the Easy Composites EG160 high temp epoxy tooling gel coat underneath their EMP160 high temp epoxy molding paste or tooling prepreg?
Im just looking to make my first mould for prepreg and am unsure which way to go.
Hi,
The eg160 moulds are very difficult to make and from experience poor quality. Every mould I have made has chipped or cracked.
Thanks
@@CarbonWorkshops that’s very helpful thank you, I will try your method in that case.
Hello. Can you tell me what the yellow call?
Filleting wax
Are your Temps in Celsius?
Yes
@@CarbonWorkshops That's super handy to know.. Maybe chuck a little c in the notes for the next one. Enjoying the vids btw.
@@M3rVsT4H Please read the description and watch the intro of the video. Both state its in Celsius.
Thanks for watching 👍
That yellow wax is bee wax???!!!
