摘要
纤维增强复合材料(FRPs)因其优异的力、热、电磁、化学等性质被广泛应用于航天、航空等领域。作为一种各向异性、非均质的难加工材料,纤维复合材料的传统加工方式存在精度、损伤及效率等问题,为其激光加工技术的快速发展提供了机遇。综述了激光加工技术在实验研究、理论与仿真等基础研究方面的进展,分析研究热点和发展趋势,指出纤维复合材料超快激光加工存在的问题及挑战;报告了纤维复合材料在激光切割与制孔、激光铣削、激光表面处理和连接技术、激光辅助成形等方面的研究及应用进展;针对航天器(特别是空间飞行器)先进制造应用,提出了纤维复合材料产品激光宏观加工和激光微细制造技术的潜在应用方向,展望了实现应用所需发展的工艺装备,以期为后续该类材料产品的激光加工应用提供参考。
Fiber Reinforced Plastics/Polymers(FRPs)are widely used in the aeronautic and astronautic industry due to their excellent mechanical,thermo-physical,electromagnetic and chemical properties.As a class of multiphase-mixed hard-to-machining materials with anisotropy and inhomogeneity,their machining problems related to machining precision,processing defects,productivity,etc.have promoted the development of laser processing of the materials.Progresses in the fundamental research on laser processing of FRPs by experimental and theoretical approaches are reviewed,with special attention paid to the research hotspots and development trends.The existing problems and challenges in current research on ultrafast laser processing of FRPs are discussed.Progresses in research and applications of FRPs,such as laser cutting and drilling,laser milling,laser surface treatment and connecting,and laser-assisted forming,are reported.For manufacturing of astronautic products(especially the spacecraft)from FRPs,the potential applications related to laser macro processing and laser micro manufacturing technologies are proposed.The equipment needed to realize the applications are also discussed.
