Coated carbon fiber
also: CFRP
Never list. At least one laser maker tells owners not to put this in the machine. Quotes below.
Bare carbon mat and resin-coated carbon fibre sheet get different answers. FSL says thin uncoated mat can be cut and coated sheet cannot.

Fumes
Every page read treats lasering as a fume source. Match your machine's exhaust figure to an extractor on the fume and room lookup.
