Effect of Laser Parameters on Surface Morphology and Material Removal Mechanism of Ablation Grooves in CFRP Composites Using Finite Element Simulations.

Based on Figure 9 , it can be found that as the laser pulse frequency increases from 50 kHz to 150 kHz, the depth of the heat-affected zone in the cross-section of the ablated material gradually increases, and the maximum can reach 16.13 μm, but the width of the heat-affected zone shows an overall trend of decreasing and then increasing, and the minimum width of the heat-affected zone is about 33.05 μm.

When the laser pulse frequency increased from 50 kHz to 150 kHz, the width of the grooves showed an increasing trend, but the ablation phenomenon also became more serious.
