The damage processes of composite laminates under impact loading and static loading after impact were analyzed based on the three-dimensional (3-D) progressive damage theory and whole-process analysis method. The influence rules of impact energy on the damage and residual strength of T300/BMP-316 composite laminates with different layer parameters and dimensions were researched. Results show that there is a threshold of impact energy for the composite laminates. The residual strength of composite laminates will decrease rapidly if impact energy exceeds the threshold value. The threshold value of impact energy for T300/BMP-316 composite laminates is between 5.0J and 5.5J. During the impact process

the dropping velocity of impactor is fluctuating

and layer parameters can influence the dent depth of the surface of composite laminates.
