超短脉冲激光加工芳纶纤维增强树脂基复合材料
Ultrashort Pulse Laser Processing of Aramid Fiber-reinforced Polymer Composites
摘要
Abstract
Aramid fiber-reinforced polymer(AFRP)is a high-performance fiber-reinforced composite with high specific strength,high modulus and light weight,and is widely used in aerospace,military equipment,automobile manufacturing and other fields.The characteristics of AFRP anisotropy and inhomogeneity lead to problems such as delamination,linting,and excessive heat-affected zone during processing,and the existing processing technology cannot reach the processing accuracy required for application in the aerospace field,which constitutes the technical bottleneck of current precision processing AFRP.This paper reviews the research status of AFRP processing,compares and discusses the advantages,disadvantages and shortcomings of traditional machining,abrasive waterjet processing,continuous laser and long pulse laser processing and ultrashort pulse laser processing,discusses the feasibility of using femtosecond laser fine processing to overcome this technical bottleneck according to the principle of femtosecond laser"cold processing",and gives the corresponding research content and related technical approaches.This paper points out the direction for precision machining AFRP,which has obvious research significance and potential application value.关键词
