Abstract: In the process of manufacturing, using and maintaining, 3-Dimensional (3-D) braided composites may subject to low-velocity impact from other objects, which will cause the damage of structure and decrease of load capacity. In this paper, low-velocity impact tests were conducted on 4-directional, 5-directional and 6-directional(4-Dir, 5-Dir and 6-Dir) glass/epoxy 3-D braided composites using Instron Dynatup 9250 drop weight impact test setup. Impact resistance characteristics were studied and the relationship between braided structure and the characteristics were established. Test results showed that braiding structure influenced the impact property evidently. Compared with 4-Dir and 5-Dir structure composites, 6-Dir braided composites needed more load and energy when main damage occurred. The damage of it continued shorter time and absorbed less energy. The major failure modes of 3-D braided composites included matrix cracking, fiber breakage when it was not being penetrated.
