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,residual 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 proposed.This paper has certain implications for the theoretical study of ultrashort pulsed laser processing of CFRP.
