摘要整理
激光辅助自动纤维铺放（AFP）技术可实现热塑性复合材料的原位固化，工艺参数对复合材料性能有显著影响。本研究系统调查了激光辅助AFP工艺参数对连续碳纤维增强聚苯硫醚（CF/PPS）复合材料性能的影响规律。采用四层CF/PPS预浸料在不同工艺参数组合条件下进行铺放，对复合材料的表面形貌、孔隙率、结晶度和层间剪切强度（ILSS）进行了表征。研究结果表明：增加激光温度和压实压力能显著改善复合材料表面的树脂分布状态。当工具温度为120°C时，复合材料的最高结晶度达到46%，而工具温度为40°C时仅为18%。随着压实力从500 N增加到2000 N，复合材料的孔隙率明显降低。通过双缺口拉伸剪切试验评估了ILSS性能。结果表明复合材料的力学性能主要受孔隙率控制，而结晶度的影响相对较小。该研究为激光辅助AFP工艺的参数优化提供了重要参考。
