It's hard for composite material to avoid being damaged due to impact during its use and the damage is also hard to be discovered by appearance of composite material.Main forms of damages include matrix crack,fiber breakage and inter-layer stratification.Among them,inter-layer stratification and matrix crack are most common and most dangerous forms of damages.This paper analyses and researches the pro-cess of damage of composite layer plate by impact with finite element software and expounds visualized pro-cessing of the result.
