摘要
超短脉冲激光加工作为一种非接触式的特种加工方法,利用高功率密度的聚焦激光束烧蚀碳纤维增强复合材料(CFRP)表面,实现高精密加工,有望解决传统机械加工工艺造成的刀具损坏、残余应力和表面质量差等问题.因此,本文综述了近些年超短脉冲激光加工CFRP的研究进展.首先梳理了超短脉冲激光加工CFRP的加工机理,其中包括了材料去除机理、相互作用过程机理和对激光的吸收与反射机理.其次,着重阐述了热影响区和锥度这两类缺陷,分析了缺陷的形成原因,并提出了相应抑制方法.本文对超短脉冲激光加工CFRP的理论研究具备一定借鉴意义.
Abstract
Ultrashort pulse laser processing,as a non-contact specialized processing method,uses a focused laser beam with high power density to ablate the surface of carbon fiber reinforced composites(CFRP)to achieve high-precision processing,which is expected to solve the problems caused by traditional machining processes such as tool damage,re-sidual stress,and poor surface quality.Therefore,the research progress of ultrashort pulsed laser processing of CFRP in recent years is reviewed.Firstly,the structural characteristics and material properties of CFRP are introduced,followed by an overview of the CFRP processing mechanism,which includes the material removal mechanism,the interaction process mechanism,and the laser absorption and reflection mechanism.Secondly,the two defects of the heat-affected zone and taper are expounded,the causes of defects are analyzed,and corresponding suppression methods are pro-posed.This paper has certain implications for the theoretical study of ultrashort pulsed laser processing of CFRP.
