title = "Dynamic Response of the Polymer Matrix in Carbon Fiber Reinforced Polymer (CFRP) under Femtosecond Laser Irradiation",
abstract = "Femtosecond laser processing is a high-precision method for processing Carbon Fiber Reinforced Polymer (CFRP) composites due to its high peak power and short pulse duration, resulting in low damage. This method holds great potential for application in the aerospace industry. This paper investigates the ultrafast dynamic response mechanism of the polymer matrix (resin matrix) within CFRP composites under femtosecond laser irradiation using a numerical model. The computation of the evolution of electron density in the resin material under femtosecond laser irradiation and the analysis of trends in instantaneous local optical property changes are presented. The prediction of ablation morphology of the resin matrix under different fluences is also included. This study offers guidance for femtosecond laser surface cleaning of CFRP composites.",
