Aramid/Kevlar

Post by Scott » Tue Apr 10, 2012 8:32 pm

This Spring/Summer I'll be laying some new glass down on the top of my boat and over the transom and maybe inside over the breasthook if I get good enough at it. I'm going to use 354 Aramid. I'm using it over glass because it handles force better. I'm over powering the Tuffy with a lighter 2 stroke, short shaft Mercury 650.

Has anyone lain this down? Should I use slow, med or fast curing epoxy?

Kevlar is not something you want as an outer layer. It does not sand, it just fuzzes up. You will want to lay glass OVER the Kevlar.

To be honest with you, ... Kevlar wont do anything for your transom. It's for impacts, so it would actually be better used on the bow at the waterline if used at all. For these small boats, ... Kevlar and Carbon don't do anything for support or strength. Carbon, can have some benefits in your transom, if it is laid up between layers of plywood. Such as, Plywood > Carbon > Plywood and such.
