Hi..
I'm new to making composite parts and after some advice..This is the first mold I've made.. Its been cleaned up since this picture was taken.. 
It's a deep Box shaped mold and have concerns about the best way to lay the carbon fiber cloth In it without getting creases. 
With something like this would it be viable to cut the cloth into multiple sections to get it in tidy.. Or would it go in, in one piece and be manipulated into place once its wetted out? 
Any advice would be appreciated..

Your best chance to avoid bridges is to cut the carbon into sections. You can use scotch tape to develop your patterns and then transfer the pattern over to poster board as templates to cur your cloth.

This is too deep to do it without cutting. Even if you could get it down, the fibre alignment would look terrible. I would go for 3 to 4 pieces: one along the length, and one for each side. If you want smaller pieces, you could split the one along the length into smaller pieces, preferably at one of the lower corners.

Certainly not. You could vacuum bag almost everything.

I would look potentially at a stabilised cloth such as our ProFinish Carbon Fibre 2/2 Twill 3k 210g.  You can cut the fabric with very little fraying and neat crisp cut lines.  You could almost make a paper template  as if you were making it from paper or card, with overlaps etc then cut the ProFinish cloth from the template and even pre-fold and crease the fabric so it fits in nicely. You might find a spray tack useful if it keeps springing away from the mould faces or tries to lift up.
