So the process is pretty straight forward. Use fabric or paper and some sort of phenolic resin. Most of the DIY recipes suggest automotive/marine fiberglass resin. Slather up your paper or fabric in the resin, make a sammich, and clamp/weight it down to ensure it's flat. What they don't mention is the types of fabrics that can be used. I've seen denim, linen, canvas, and even old T-shirts used. What I haven't seen is something like Cordura used. I have a few of yards of 1000d Cordura that I picked up a couple summers ago to have my motorcycle jacket fixed. I have enough left over to make another jacket or some pants and a LOT of micarta. I'm only wondering if the Cordura will melt into something nasty when it comes into contact with the resin, or if it'll be too brittle to shape.
