I have found that cutting Kevlar by all the normal means is extremely difficult.  Worse than that trimming and finishing edges of vacuum bagged parts containing kevlar has never been satifactory.  Kevlar edges always seem to get fuzzy and never look right.  Does anyone have some advice on a) cutting kevlar to produce a clean edge and b) (most importantly) trimming and finishing kevlar edges?


Thank you.

Kevlar is nothing short of a nightmare to trim. You have the same chance of sanding a burlap bag to a high gloss finish as you would with kevlar.

When you embed kevlar try never to have it reach the perimeter where you will actually do the trimming of you carbon panel.

If you do get fibers exposed the only way I have found to push them down is to wet them with resin and then use plastic sheet over the area and tape down firmly with clear packaging tape. Build up resin over the area once cured and you have removed the tape. (light scotch bright first, but do not expose the fibers) Carefully flat out the resin. If you break through your toast again and will have to do the whole thing over again.

If anyone knows how to cut kevlar or better yet drilling a clean whole through it I would really like to know how myself.
