Mechanical response and damage evolution of CFRP laminates under coupled thermal-impact loading

This study investigates the mechanical properties and dynamic damage characteristics of CFRP laminates under coupled thermal and impact loads. Through thermal environment simulation, impact loading, and multidimensional data acquisition, experimental data on velocity, acceleration, stress-strain, and energy absorption were obtained. The results show that the heat-impact coupling effect significantly degrades the material’s mechanical performance. This study provides a research foundation for enhancing the structural performance of CFRP under thermal shock, and lays a scientific basis for its engineering application under complex service conditions.
