Dynel is good stuff, and often recommended for wooden boat decks (over marine plywood). I used a lot of it on a sailboat.
It does really absorb a lot of epoxy, and also tends to float up in the epoxy, so not the choice for light weight unless you are vacuum bagging, IMO.
Mike- where did you find dynel tube? I hardly see the cloth for sale any more; I recall I had to go to Defender years ago. Nowadays there are more online suppliers for composite supplies.

About the toughness- I never found it really tough, but I'd done some work (unwillingly) with Kevlar, so perhaps my frame of reference was different.
