I am gaining a contract to make 75 36x36 flat pieces of carbon. They need to be 3/32 in thickness. I have found some really thin foam core but I can get some coremat for pretty cheap. These parts are going the be rc chassis’s so they are just going to be waterjet cut out. But they still need to be ridged. Will the coremat make it as ridged as I need it. How many plys of carbon would you suggest too? Just tring to get your experiances without the trial and error to get it exactly how I want
The paper coremat needs the sides to be sealed in a border of cloth and resin otherwise any moisture may swell it up. But test it fully and see for yourself.
You might want to use fiberglass in the center but the company that is paying you should dictate what they want. I hate for you to make all these and then they say they wanted 100% CF!
so the core mat does not full saturate? So I can not just make a sheet and have it waterjet cut out becaues it will leave the side exposed, am I correct
Correct. If you don’t have ave any Perf. paper coremat, I might be able to send you some scrap since you help out on here! 
You only stick it down and not saturate it as then it will get really heavy then!
will the foa core do the same with moisture as the coremat?
I doubt it but with foam core I’d be thinking that the foam core would seperate unless each chassis is individually laided up.
I C , hmmm looks like I got some playing around to do
I know of a member on here that has Tri-axial CF (might be really thick) and the class was getting a donation but we keep missing one another…:rolleyes:
