碳纤维复合靶板抗破片冲击性能研究
Study on Anti-Fragment Impact Performance of Carbon Fiber Reinforced Plastics
摘要
Abstract
In order to explore the anti-penetration property of carbon fiber composite materials,a series of experiments need to be carried out.In experiments,8 g cubic steel fragments penetrated carbon fiber reinforced plastics whose thickness are 5,10 and 15 mm respectively.The velocity of fragments was obtained,the situation of target was observed,fragments and carbon fiber were recovered.The numerical simulations were carried out according to the situation of experiments.The process of fragments penetrating carbon fiber composite target was explored,and the failure mechanism of carbon fiber composite target was also explored.The relationship between the failure mode and velocity of fragments could be described as follows:when the fragment velocity exceeds the ballistic limit,the main form of target damage is fiber shear failure;when the fragment velocity is lower than the ballistic limit,the damage forms of the target include fiber shear failure,fiber tensile failure,matrix cracking and fiber layer delamination,and their proportions change with the fragment velocity.关键词
