For abrasion resistance carbon is definitely the right material. Neither
is Kevlar. Kevlar fuzzes up and carbon fiber is not flexible enough. Best
to use is a tight weave e-glass cloth and fill the weave with epoxy with a
large addition of powdered graphite. That is a pretty standard bottom for
McKenzie style drift boats.

I'm building a duck hunting layout boat, and it will probably face alot of
dragging across dirt/gravel. I'm thinking of doing the bottom in carbon
fiber.

anyone have a cheap source for carbon fiber?

anyone have a better idea?

Thanks,

Marc
