The low-velocity impact and compression after impact(CAI)properties of three-dimensional(3D)five-directional carbon fiber/epoxy resin braided composites were experimentally investigated.Specimens prepared with different braiding angles were tested at the same impact energy level.Residual post-impact mechanical properties of the different configurations were characterized by compression after impact tests.Results show that the specimens with bigger braiding angle sustain higher peak loads,and smaller impact ...
