介绍了用Nd：YVO4皮秒脉冲激光系统切割碳纤维增强塑料的实验研究。采用单因素试验设计，研究了激光功率、切割距离和切割速度对脉冲激光与材料相互作用的影响。采用响应面中心组合设计法对工艺参数进行优化。通过光学显微镜观察，对切缝宽度、锥角、材料去除率、热影响区等进行了讨论。采用皮秒脉冲激光、纳秒脉冲激光和常规切割三种不同的切割工具对试样进行切割，并进行拉伸强度和弯曲强度测试。此外，还分析了热影响区对静强度的影响。
An experimental investigation of carbon fiber-reinforced plastics cutting with an Nd:YVO4 picosecond pulsed system was presented. One-factor experimental design was used in order to explain the influence of cutting parameters including laser power, hatch distance and cutting speed on the pulsed laser-material interaction. The process parameters were optimized by using central composite design of response surface methodology. The results in kerf width, taper angle, material removal rate, and heat-affected zones were discussed through the micrographs observed with optical microscope. Specimens were cut with three different tools: picosecond pulsed laser, nanosecond pulsed laser, and conventional cutting, and the tensile strength and bending strength tests were conducted. Furthermore, the effect of the heat-affected zones on the static strength was also analyzed.
