The influence of the impact energy on the impact damage of the carbon fiber fabric reinforced epoxy composites laminates was investigated. Impact tests on the carbon/epoxy composite laminates with the size of 600 mm×700 mm were conducted with different the impact energy levels from 5 J to 65 J at the room temperature, respectively. After the impact test, the impact crater depth and the matrix length was measured on the tested specimens. The calipers and three-dimensional microscope was used to
