Laser drilling and cutting of carbon fiber reinforced polymers: Parameter selection and intelligent optimization – A review

Carbon fiber reinforced polymer are widely used in high-performance fields such as aerospace and automotive industries due to their exceptional mechanical properties. However, due to their anisotropy and heterogeneity, traditional machining methods often result in defects such as burrs and delamination, which increase processing difficulty. Laser processing technology, as a non-contact machining technique, offers numerous advantages in the processing of carbon fiber reinforced polymers. With its high precision and efficiency, laser processing can effectively avoid defects commonly encountered in traditional machining, particularly in reducing thermal damage. This paper reviews the application of laser technology in CFRP cutting and drilling, examining the impact of processing parameters such as laser wavelength, mode, frequency, scanning method, and auxiliary techniques on processing quality. The paper focuses on the critical application of mathematical methods and machine learning algorithms in optimizing laser processing parameters and improving processing accuracy and efficiency, while also forecasting future trends in CFRP processing technology.
