Don't know. I've had this Kevlar thread for years, don't remember why I bought it. I smeared the JB Weld on the wood and brass tube, wrapped the thread into the JB Weld then rubbed the JB Weld around the threads. Rock solid.
It's just very difficult to trim post layup and as far as the wetting it's not as spongy as glass... Would be neat to laminate it in between glass layers for strategic support in areas prone to abrasion, flexing, or impact. Composite gliders use thin kevlar weave strips for the hinge material molded into the wings and tails.
