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.

You can cut kevlar with a decent pair of composite scissors its a slow process, an inch at a time but it does work. If you wet sand edges with 1200's you can get nearly as good a finish as with normal carbon. For drilling I clamp the part between two pieces of perspex, grind the drill bit at a similar angle to that required for sheet metal ie quite steep/pointed.

Thanks for the tips. What is perspex?
