Carbon Fibre Sheet 2mm (all carbon 3k)

What price for 3 mm and 1.5 mm that size.
you say carbon throughout are the unner layers woven or unidirectional, at that price it sounds like woven a it pricey for unidirectional internal content carbon.

Eddy not so sure water jet is such a good idea I was going to cut my carbon in a water bath until I said this to the people that manufactured the carbon for me, they warned me against that as water can get into the carbon through the edges thus lowering the strength of the carbon.
they cut with a Cnc and an industrial dust extraction system, I will be doing similar but with the Cnc in an enclosure with a vacuum cleaner for the dust extraction.

Most people I know who cut their own multicopter/drone frames or helicopter frames from carbon do so with abrasive/rasp/diamond coated type cutters and do so in water baths, I've never heard of them having frame failures because of water absorbtion when cutting the frames. If you're worried about water ingress down the fibres then why not dry out the cut carbon in a warm place overnight (the wife's airing cupboard) before using it as a precaution?



If you look at Haydn's channel you'll see the things he makes on his CNC router.

Ah I see.
the idea of a water bath was literally that, a tray filled with water the carbon would be submerged in the water for while cutting then the water drained off and the carbon removed, dried and cleaned. My comments were from the manufacturer who comes from an arospace background so a small loss of strength is a big thing for them.
i see on the video that his water bath is not so much a waterbath as a cutting in a water jet with the outflow of water being collected in the bath and then drained into a large water container in this case a fish tank it looks like he has a small tank ata he'd to the spindle and the water is fed to the cutter by gravity I may be wrong on that.
I have a fealing that modifying the waterbath to be similar to haydn's might just work.
