: Like Lee said, felt is a waste of epoxy...unless you vacuum bag it. Kevlar
: also "floats". It's much less dense than epoxy, and you'll
: actually end up with a pool of epoxy under the felt, with the epoxy
: floating over it, not quite saturated. You continue to add saturation
: coats and the kevlar continues to rise higher. A definite candidate for
: vacuum bagging.

: You'll have high abrasion resistance, but your impact resistance comes from
: teh glass and birch. The kevlar will flex without deforming, past a point
: where your glass and wood will have cracks. If you want impact resistance,
: go all kevlar, or plan on the glass providing that protection.

: I want to build my own kevlar boating helmet!

I'm in the middle of a helmet building project. going to make a helmet with slight shape of a cowboy helmet as I am a rodeo boater! If you want to bounce any ideas off me go for it.
