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.

Same cutting disc here. 1mm thick and i tend to use angel grinder for all but smallest cuts. 

I start with 400 wet for kevlar hybrids (for rough trim you can also use 320 sanding tools like Permagrid but it helps if you only work in one direction)  and i find that finishing edges with 800 is good enough in my bookSmile 

Coarse paper like 80/120 will leave exposed fibers hanging.
