摘要
Abstract
3D fabric composites exhibit promising application potential in the field of impact-resistant aerospace structures.This study conducted over 30 ballistic impact tests using a titanium alloy cylindrical projectile and 3D fabric composite plates,with projectile velocities ranging from 160～280 m/s.Various impact test results such as re-bound,embedding,and penetration were obtained,along with different damage forms of the composite target plate.Based on these test results,the impact properties and damage mechanisms of three different structural composites(3D 4 direction braided,3D 5 direction braided,and 3D orthogonal woven)were analyzed.It is indicated that after being impacted by the projectile body,all three structures exhibit similar damage patterns characterized by local fi-ber fracture and matrix cracking at the point of impact without any lamination.The damage region of the 3D 4 direc-tion braided structure is a sharp angle cross shape,while the damage spread along the braided direction.The dam-age region of the 3D 5 direction braided and 3D orthogonal woven structure are diamond-shaped,while the damage spread along the 90°and 0°direction.Comparing the three structures of specimens in this paper,it is found that the ballistic limit of 3D orthogonal woven structure is highest while its corresponding damage area is smallest.关键词
