i am no chemist, but i was told by someone that i trust that the reason kevlar fuzzes up when you sand it is because there is only a mechanical bond, whereas carbon and glass have the mechanical and chemical bond.

You ALMOST got it correct ...
When you place a cotton T-shirt in water, Ya get a WET
cotton T-shirt ; the water actually permeates the cotton
fibers.
When you place a carbon in water, Ya get a WET
carbon ; the water actually permeates the carbon
fibers.
NOT SO with Kevlar,when Ya place Kevlar in water
the water dos NOT permeate the actual fibers.
It's kinda like placing a plactic comb in water, Ya
get water dripping down the sides of the plactic, but
it doesn't soak through.
That's One reason Kevlar doesn't work for Squat for a bond
on Nomex-Honneycomb !

BTW, the glass fibers in that mix i suggested ...
DOES make it structural.
