Using hemp fabric instead of fiberglass

What are the mechanical properties of the fiber and how does or compare with graphite, Kevlar, or FG? The fibers by them selves have no strength except in tension. Resin stabilizes fibers to give them strength, for most repair applications one would do on a FG RV just about any fiber will work. I have used old bed sheets and epoxy resin for repairs. Repairs usually fail in the bond line not in the fiber matix. Where would you commerially buy woven hemp?

Bit of googling got this

. I could not find any mechcanical properties for the fiber. What I did find is a lot of pro marijuana sites saying it is 10 times stronger that steel. The use of cellulose and other renewable fibers have been looked at for years and are light and impact resistant but never had the strength of FG epoxy or graphite epoxy for structural use.
