Composite Questions, Mark 2

Sign in to disble this ad
Again I research the merits of composite materials, and I believe I have something (again):

Mixing graphite (powder) with epoxy resin is nigh useless - it's basically granules suspended in a resin - no added stability. However, fibers mixed with the resin is another story. From what little information Steinberger World (the most authoritative Steinberger site on the internet, surpassing even the official site) gave me, I gathered this was how Ned did it in 1979.

However, one thing I DON'T understand: when you cut the body (or mold it, really), what happens when the fiber mixture is cut? Are fibers exposed, and the structure weakened when they're cut into curves, like what happens when you try to do something similar to a rib of celery (there is absolutely no better analogy than the celery)?

This, aside from the general difficulty surrounding finding the graphite and kevlar fibers, making the mold, and actually putting all of this together, may be my only problems with going with a woodless option (and there are many reasons to do this).
