Hy guys,

I was wondering did anyone maybe sucessfully made carbon moulding paste for high temperature moulds to use with pre preg? Like chopped fibers, some fillers (aluminium?) and high temp. epoxy? Or maybe just mix "virgin" chopped fibers and high temp epoxy to fill all the grooves and stuff?
It would go on EC high temp gelcoat and little print through is not a big problem because I will spray clear coat later on so surface finish doesn't have to be perfect. 

I have fairly complex plug to make mould of and would highly benefit if I can use paste instead of fabric to make mould. Actually I would cover it with paste, get it as square as possible and than cover with fabric to add stability.
I would like to avoid fiberglass paste because it would be multiple - run mould that requires dimensional stability and object is long and not very wide (approx. 130x10x4cm)

Also, if this is not possible, does anyone have experience with carbon non wovens as first or first few layers on complex moulds?
