Top side of the carbon plate - three layers of unidirectional carbon cloth in one direction and three in other direction - alternating. Makes very rigid plate. Tape makes the handling and cutting easy. Cured under full vacum on polypropylene sheet (very shiny and requires no wax). Nylon cloth was used as peel ply - on top of the nylon were many layers of toilet paper to absorb the extra resin. I used very slow hardener and heated the layup at the beginning of the curing (put a pot with hot water on top of the bag), to make the resin very thin and get most of it out.
