| 摘 要： | This paper studied the impact resistance of 3D integrated cellular woven composite panel under persudo-static impact, comprised the test result with property of typical 3D woven composites, analyzed some parameters that maybe affect composites＇ impact resistance and at last used SEM to observe the damage process and mechanism of samples. The result shows that the impact resistance of 3D integrated cellular woven composites is much better than the performance of typical 3D woven composites; it is an active method to improve the impact resistance of composites that developing preform with cellular on the basis of typical 3D woven structure; for different 3D integrated cellular woven structure, the value of absorbed-energy is increasing with the hollow percentage; tiny deformatlen will not emerge on samples until the acting force gets to 85% of the maximum; similar with typical 3D woven composites, the delaminated phenomenon of 3D integrated cellular woven composites is also unapparent during impact process.

| Abstract: | This paper studied the impact resistance of 3D integrated cellular woven composite panel under persudo-static impact, comprised the test result with property of typical 3D woven composites, analyzed some parameters that maybe affect composites' impact resistance and at last used SEM to observe the damage process and mechanism of samples. The result shows that the impact resistance of 3D integrated cellular woven composites is much better than the performance of typical 3D woven composites; it is an active method to improve the impact resistance of composites that developing preform with cellular on the basis of typical 3D woven structure; for different 3D integrated cellular woven structure, the value of absorbed-energy is increasing with the hollow percentage; tiny deformation will not emerge on samples until the acting force gets to 85% of the maximum; similar with typical 3D woven composites, the delaminated phenomenon of 3D integrated cellular woven composites is also unapparent during impact process. |
