研究了激光切割碳纤维复合材料(CFRP)过程中碳纤维的铺设方向和树脂含量对激光能量传递方向以及切割质量的影响。根据复合材料混合定律设定材料物理参数，建立了碳纤维铺设角度为0°、45°、90°，树脂含量由30%增至50%的单层CFRP三维有限元模型。数值模拟结果表明，激光多向切割单层CFRP时，烧蚀前沿的能量传递方向由激光切割方向主导；随着纤维铺设角度的增大，传递方向的角度增大；稳定切割时能量传递主要沿纤维铺设方向。随着纤维铺设角度的增大，切缝倾角增大，表面碳纤维烧蚀宽度几乎不变，温度场变宽，最高温度降低。切割不同树脂含量单层CFRP时，热影响区宽度和最高温度随树脂含量的增加都呈近似线性变化。与试验结果相比，数值模拟结果中的表面碳纤维被烧蚀宽度的平均误差为10.66%，热影响区宽度的平均误差为13.09%。

The effects of carbon fiber orientation and resin content on the laser energy transfer direction and cutting quality during laser cutting of carbon fiber reinforced plastics (CFRP) are studied. According to the mixture rule of composites, the parameters are set, and the three dimensional finite element models for single-layer CFRP with carbon fiber orientations of 0°, 45°, and 90°, and resin contents of 30% to 50% are established. The numerical simulation results show that, during the multi-directional laser cutting of single-layer CFRP, the energy transfer direction is mainly dependent on the laser cutting direction, and the angle of transfer direction increases with the increase of fiber orientation angle. As for the steady cutting, the energy transfer is mainly along the fiber orientation direction. With the increase of the fiber orientation angle, the dip angle of kerfs increases as well, the width of burned carbon fibers on the surface does not essentially change, the temperature field becomes wider, and the maximum temperature decreases. When the single-layer CFRP with different resin contents are cut, the width of heat affected zone and the maximum temperature both have approximately linear relationships with the resin content. Compared with the experimental results, the average errors from numerical simulations for the burned zone width and the heat affected zone width on carbon fiber surface are 10.66% and 13.09%, respectively.
