“…In addition, there was no obvious ablation in the CFs in these two zones because of the relatively low temperature. However, in the ablation center of the thermoset composite, the resin and carbon fibers were decomposed or sublimated directly, and there was no clear transition zone [9,10]. These differences will greatly affect the residual strength of the composite after laser ablation.…”

“…Ferrante et al [8] investigated the effect of basalt fiber hybridization on the damage tolerance of carbon/epoxy laminates subjected to laser shock waves and found that such sandwich structures had excellent damage tolerance. Kaludjerovi et al [9] studied the ablation behavior of carbon/epoxy composites under pulsed-wave (PW) laser ablation at different energy densities. The depth and area of the crater-like ablation zone were quantitatively analyzed by ImageJ software, and the ablation area curve under different energy densities was fit.…”

The ablation mechanism and performance of carbon fiber (CF)-reinforced poly aryl ether ketone (PAEK) thermoplastic composites were studied in this paper. The results show that the ablation damaged area is controlled by the irradiation energy, while the mass loss rate is controlled by the irradiation power density. In the ablation center, the PAEK resin and CFs underwent decomposition and sublimation in an anaerobic environment. In the transition zone, the resin experienced decomposition and remelting in an aerobic environment, and massive char leaves were present in the cross section. In the heat-affected zone, only remelting of the resin was observed. The fusion and decomposition of the resin caused delamination and pores in the composites. Moreover, oxygen appeared crucial to the ablation morphology of CFs. In an aerobic environment, a regular cross section formed, while in an anaerobic environment, a cortex–core structure formed. The cortex–core structure of CF inside the ablation pit was caused by the inhomogeneity of fibers along the radial direction and the residual carbon layer generated by resin decomposition in an anoxic environment. The description of the ablation mechanism presented in this study broadens our understanding of damage evolution in thermoplastic composites subjected to high-energy CW laser irradiation.
