The properties such as dent depth, residual compressive strength and compressive failure strain of 3 groups of T800 carbon fiber composite laminates with the same layer ratio and different thicknesses were tested. The results show that there inflection points are existed both in impact energy-dent depth curves and dent depth-residual compression strength curves. The inflection points of the 3 groups are at the depths of 0.70 mm, 0.76 mm and 0.45 mm respectively, which are less than the depth of dent (1.3 mm) corresponding to barely visible impact damage (BVID). With the same ply ratio, the greater the thickness of composite laminates, the better the impact damage resistance.
