I know this is from 2 years ago. But you could drill a tiny holes or multiple in the mould. Cover the mould surface holes with wax (small amount). Then once cured blow air or water in to the holes to pop the part out.
Hey Thanks! Carbon fiber the actual material resistant to high temp, petrol, gas. The resins or adhesives are the more sensitive to ethanol and heat. You have to use the right stuff for the job. I’m using prepreg carbon fiber which is resistant to heat up to 130c. Resistant to ethanol but in time the ethanol slowly brakes down the resin. I used petrol resistant clear coat for the protection. 👍
Hi, did you have any issues with the resin de laminating from the epoxy gel? Iv thought about doing this buy easy composites always said it won't work. And reason you didn't use the uni mould. Coupling coat?
Hi! The reason I used it. It was cheaper, works better in cold environment. It works perfect if you let the gel coat fully dry. Only baked the part at 90 degrees for 8 hours. It was just a test piece 🤟
@@zrcarbon9937 nice, I made one like that now and took it to 120deg. Was all good. I applied onto tacky gel tho and had a couple of repairs. Will try onto fully cured gel next time.
the only problem is you use unimold system which is up to 90 C but the actually pre peg should be sit on 120 C for 2 hours att he end of the heat cycle. still thought good results. You need 2 parts mould for your engine head cover, as there are some parallel sides. I am assuming the pre peg is not from Easy composites ?
He used high temp gel coat eg160. Good up to 160c. The normal resin can probably handle oven temp up to 130. It did not cause any issues here. But to be safe he could have used the high temp laminating resin aswell. If he is using 210 twill is probably from easy composites. They are pretty much the only suppliers of xc110 in Europe and UK.
Hi! Yes I did remove it. Unfortunately I lost the footage between making the mould and laying the carbon fiber. My next video will be very detailed. Definitely watch out for it! 🛠👍🏻
@@zrcarbon9937 i will for sure :) is this how the size difference is created so the cover sits so snug? Because making a mould generally means you’re duplicating the exact shape of the product yet you created a perfect cover :)
Next time ,debate and remove film then put back in oven , ramp up to cure temp, then the parts should fall out. Large difference in cte of part in relationship to e glass mold.

This turned out better than expected! Well done!

Thanks for the advice.
I’ll use this method next time for something else 🛠️🤘
Hello. at what temprature did you bake the prepreg in? because you used unimold tooling resin on the mould.
Hi!
I used 90 degrees for 12h.
Clutch and valve cover COVER, gotcha.
I really enjoy these videos. Question : How does carbon fiber hold up to oil, high temperature , and gas ?
Hey
Thanks!

@@zrcarbon9937 thanks for the response. I'm going to try and make some covers for my 2007 vtx 1300c engine build.
Definitely give it a try! 🛠🏍🤟
the best question is how long can it hold 😂
@@itzerisadomeeiot4980 Time will tell my friend 👍
Thats look so awesome dude 😍
Thanks so much! More is coming soon!🤟

hello. Does high temperature epoxy give good results with polyester fattening resin for high temperature mold?
Hey
I had no issues with the two components being used together for HT moulds
Thanks for watching 🛠🤘
So does that wax sheet stay in the mould or does that come out after the fiber glass backing goes on?
Have you ever made a flag pattern or other designs/logos into your carbon fiber designs? Would be cool to see if you haven't already tried that.

Como pides la cera calibrada o en qué plataforma de Amazon o AliExpress lo podría conseguir?
Hi
I bought the wax from easycomposites.co.uk
@@zrcarbon9937 thks! Bro
VIP👍
Thanks so much! I appreciate it 🛠🤘
Deberías implementar el uso del PVA (alcohol polivinilico) para evitar que se adhiera la pieza final al molde
I used chemical release agent.
Hello which gelcoat and which laminating polyester resin do you use?
thanks mate
by the way cool video!
Hey!
I was using easy composite products, high temperature gelcoat and tooling resin.
Thanks for the compliment!
@@zrcarbon9937 Thanks! 💪🏻
Have you removed the wax sheet at some stage? I don’t see the sheet when you’re laying the carbon pieces inside of the mould

Yes, you’re exactly right
where'd you get that pump? I need one !
Hey
Did you mean the vacuum pump?
Easy composites
www.easycomposites.co.uk
So these are just covers for actual aluminium parts. I was expecting to see some real lightweight cf stuff.
Just covers awwww how cute I thought there was serious carbon fiber business a foot damn.
Where did you get that wax??? Thanks!!!
Easy Composites
Hi , what's the name of the yellow material?
Yes I'm interested too
Where did you get the wax from?
Hey
I sourced the wax from easy composites
@zrcarbon9937 thanks!!!

hye.. can you share tooling resin mixing ratio
Hey
I used 2% for that layout. The weather was little too cold. During the summer I use 1% hardener. 🛠️🤘
2:57 what is the pasta lasagna looking sheet he uses to mold
Hey
Called Wax sheet.
You’re using your scissors upside down my friend
