Hi everyone, I have 2 questions about cutting CF preperg:
1) what would be the best way to cut complex shapes out of an uncured CF prepreg sheet? I have access to kevlar scissors and an electric shear, but they aren't ideal when I'm trying to cut inclusions within the fiber (let's say like cutting a donut in the fiber - cutting a hole in the middle is difficult with shears). Is there anything like a boxcutter for CF prepreg?
2) For post cure cutting of a laminate/part, what would be the best or least damaging way to cut its shape, without compromising on structural properties? Currently using a dremel saw max with a diamond blade, does a decent job but my part delaminated under loading, so was wondering if there was anything better (like water jet maybe?)
Thanks!

what hanaldo says, Ive literally just been cutting some plies out for an intricate job and used the smae stanley blade for both cutting the lightweight 240gsm and the heavy duty 650gsm prepreg.
Just watch your fingers!!!
