ABSTRACT:
A method for cutting epoxy/carbon fiber composites of carbon fibers in epoxy resin uses a diffraction-limited neodymium (Nd) yttrium-aluminum-garnet (YAG) laser operated in a high peak power Q-switch mode at high pulse rates. The fiber composite is cut with minimal heat affected zone. Selective and multiple wavelength processing are applied for increased coupling efficiency with the epoxy and carbon material components of the composite.
