so this isnt your typical car carbon fibre questions.

The "lost foam" method is good for one offs or if you want no joins. You in effect carve yourself a plug out of styrofoam (it must be styrofoam).  Then using epoxy based resins you lay over your layers of carbon and wet it out in the same technique you would do for simple wet lay techniques. You then lay up ideally some coating resin like found in the bonnet skinning kits to build up resin to give you a surface you can sand smooth. once the thing is properly cured, you pour acetone into the middle through a hole and the acetone will dissolve the foam. You can then just pour out the liquid leaving a hollow carbon shape.

You cant use polyester resin as it will dissolve the resin.  Also you must ensure the epoxy is cured before you play with acetone as uncured epoxy can be broken down with acetone.


You wont get far using kitchen scissors to cut carbon! they will snag easy and blunt real quick.  decent carbon shears cut through carbon real easy.
