Quasi-static Impact behavior and Energy Absorption of 3D Integrated Cellular Woven Composites
The quasi-static impact behaviors of 3D integrated cellular woven composites were tested on the RGM- 2000A electronic universal testing machine. The load- displacement curve and energy-displacement curve were obtained and the impact resistance of the composites with different cellular shape was analyzed. It was found that load-displacement and energy-displacement curves are both sensitive to the shape of cross- section. The existence of cellular in the structure influences the ability of impact resistance to a certain degree. Under quasi-static perforation, matrix cracking is the damage mode at the front side, the fiber breakage and pull-out can be found on the back side. Furthermore, delamination mainly appears at the connecting area of the cellular and non- cellular portions, and facings of the composites owe higher delamination resistance because no delamination is found in the perforation test. Higher delamination resistance can be realized by larger density of the vertical yarn and higher crack resistance of the composites can be induced by larger yarn density.
