can you laser cut carbon fiber

Hi everyone,

I’m testing a YiHai 1500W fiber laser to cut carbon fiber sheets, but facing issues: edges charring, resin smoke, and potential delamination. How do I balance power and speed to avoid thermal damage? Does YiHai’s pulse modulation or air-assist calibration help reduce resin overheating? Also, any tips for securing thin carbon layers without warping during cutting? Worried about nozzle contamination from debris—are there specific filters or settings to protect the laser head? Your expertise could save my project (and the machine)!

Thanks,
Bluces
 
Is this okay?
Drop power (start ~300W), boost speed (try 8m/min), enable pulse (2000Hz/<50% duty) + max air assist (8Bar, nozzle close!) – kills charring/delamination/smoke.
