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.

Keeping the fibres away from the perimeter is good advice. Like everyone said cutting Kevlar is difficult. My best method may not suit everyone but I use a box cutter with a brand new blade and trim the part just when it's gone past the green stage. It may require opening the vac bag etc but it beats all the other futile attempts at a fully cured part.
