How many layers for 3cm flat sheet?

I can only imagine infusion would be pretty useless for this as vacuum will have hard time pushing down that thick of a sheet so I'm thinking wet lay up and put something really really have on top to compress. What say you? Also, most importantly, how many layers do you think i'm gonna need to build that kind of thickness? Regards, Stan

I.e., shredded CF with Resin stuffed into a metal mold, and precision cut pieces of very fine weave prepreg CF for the top and bottom layers. Use high pressure "workshop hydraulic press" and heat the mold with an oil heating system. I'm working on such a setup to make CF / Carbon Nanotube rifle-scope mounts. They will have molded in threaded Titanium studs for the assembly screws.. Dravis, That was my first idea but making forged carbon cases is not as easy. At least for me. I've no idea about the technology and I will surely need a very good press to compress the two pieces of mould. Possibly hundreds of killograms. And it would be very expensive to make the moulds since I it is essentially a two piece mould. Making the case from layers is much more simple. Doesn't look as good as forged carbon (I have a forged carbon Audemars Piguet) but still looks nice. Looks different Regards, Stan
