I make a lot of carbon kevlar panels and parts for rally car and always have the same problem 
when trimming & drilling parts.

When I cut the finished part to size I always get a fluffy dry cloth frayed edge not a sharp clean edge 
like when I make carbon parts. Why is this.
Even if I drill a hole right in the middle of a part it has a frayed edge.

My process is hand lay up 1x Carbon Kevlar, 2x Diolen, 1x carbon kevlar using epoxy resin and then vac bag.

Any help appreciated.

You're using a material that is renowned for its abrasion resistance, and then surprised when it doesn't abrade cleanly...

So are you saying this is a normal finish for Kevlar?

Here are some pictures of what I am working on, I don't know the science behind the products etc I just 
put stuff in a mould.

Cut with angel grinder and then use finer grids (at least 400) to wet sand it.
