Selective processing of CFRP by two-color double-pulse femtosecond laser
Abstract:
This paper employed a two-color double-pulse femtosecond laser (TDFL) technology for surface processing of carbon fiber reinforced polymers (CFRP). By exploring the changes in ablation thresholds for resin and carbon fiber under varying wavelengths and pulse numbers, optimal wavelength combinations were identified. Adjustments to processing parameters and pulse delay enabled precise removal of the CFRP surface, targeting resin while causing no damage to the underlying carbon fibers. After laser treatment, the CFRP surface showed modifications in surface roughness and wettability, improving adhesive bonding with binders or coatings.
