The disadvantages of kevlar are poor compressive qualities, it is stretchy (particularly grade 29), the fibers absorb moisture, very difficult to work with (difficult to cut and drill through, even when cured).
Being so nasty to work with is what makes it great at what it does best. I've used it on boat keels and areas where abrasion resistance is desireable.
I think epoxy/glass is the answer. It's cheap and extremely strong. |
