为研究高速冲击条件下TC4/PEEK/Cf层板破坏失效行为和机理，采用空气炮高速冲击实验探索了纤维取向对层板抗高速冲击性能的影响，并建立了误差有效控制的有限元模型。使用验证后的模型对不同变量下层板冲击实验进行算例丰富。实验和模拟结果表明：TC4/PEEK/Cf层板高速冲击下损伤模式主要是金属/复合材料界面分层、复合材料内部层间分层、金属塑性变形、复合材料撕裂断开等。通过对比不同纤维取向层板高速冲击破坏特征发现，TC4/PEEK/Cf层板抗高速冲击性能与纤维铺放角度有关。层板整体耗散冲击能量的性能随纤维交叉角度增大而提高，纤维单向铺放层板的弹道极限和能量耗散率最低，0°/90°纤维取向层板的弹道极限和能量耗散率最高，抗冲击性能最优。
Abstract
In order to study the failure behavior and mechanism of the laminates under high speed impact condition, the influence of fiber orientation on the high speed impact resistance of the laminate was explored by using air cannon high speed impact test, and the finite element model with effective error control was established. The model verified by optimization is used to calculate the impact test of the laminates with different variables. The experimental and simulation results show that the main damage modes of TC4/PEEK/Cf laminates under high speed impact are metal/composite interface delamination, internal lamination of composite, plastic deformation of metal and tearing and disconnecting of composite materials. By comparing the characteristics of high-speed impact failure of TC4/PEEK/Cf laminates with different fiber orientations, it is found that the high-speed impact resistance of TC4/PEEK/Cf laminates is related to the fiber placement angle. The impact energy dissipation performance of the laminates increases with the increase of the cross angle of the fibers, the ballistic limit and energy dissipation rate of fiber one-way laminates are the lowest, the ballistic limit and energy dissipation rate of 0°/90° fiber oriented laminates are the highest, and the impact resistance is the best.
