Ablation behaviors of carbon reinforced polymer composites by laser of different operation modes

Abstract: a b s t r a c tLaser ablation mechanism of Carbon Fiber Reinforced Polymer (CFRP) composite is of critical meaning for the laser machining process. The ablation behaviors are investigated on the CFRP laminates subject to continuous wave, long duration pulsed wave and short duration pulsed wave lasers. Distinctive ablation phenomena have been observed and the effects of laser operation modes are discussed. The typical temperature patterns resulted from laser irradiation are computed by finite element analysis a… Show more

“…surface fabric layer without obvious change to the main body of the laminate [4]. The interaction between the long pulse Laser and the CFRP composite laminates is further investigated in the present work to reveal the drilling procedure of the specimens by the pulsed infrared wave Laser of duration about 200ns.…”

“…The failure mode is dependent on laser powers, material properties, structural features and environmental parameters. The thermal deformation induced by the thermal stress through non-uniform temperature distribution is the main failure mode of structures under low-power CW laser irradiation [19]. The laser also reduces the stiffness and strength of a target when temperature is below the melting point of a material [20].…”
