摘要：
As the 3D woven composites have broad application prospects in aerospace and high-speed train body structures, exploring their strain rate effects is fundamental to enhancing their out-of-plane impact resistance during service. This paper conducts experiments on the impact behavior of 3D woven composites under different strain rates in three directions and validates the established mesoscale finite element model. By comparing experimental and simulation results, it is found that the peak stress and maximum strain during impact compression show significant strain rate effects in all three direc...
