Experimental and numerical method were employed to determine impact resistance of the 30 layer-aramid fabric compositeby. Firstly, the multi-layer fabric composite was fabricated and specimens were prepared according to theexperiment requirement. Secondly, the bullet impact experiment was implemented to obtain mechanical performance of the composite, such as interface delaminate, fiber fracture. Thirdly, the FEM model was set up in Abaqus, and Hashin criterion and Cohesive element were adapted to simulate behavior of composite failure and interface delamination. The information of displacement, strain field, velocity of the bullet were obtained. Finally, FEM simulation result was compared with experiment result, ballistic performance of the composite under impact load was analyzed, which contributed to engineer application.
