摘　　要：为解决当前T字型铺层复合材料抗层间剪切能力弱的问题,通过对复合材料预制件织造工艺进行合理设计,使用SGA598小样织机织造了T字型织物,采用真空辅助树脂传递模塑(VARTM)工艺将其制备成复合材料,并研究其在低速冲击下的抗冲击性能;使用有限元软件ABAQUS建立了几何与材料模型,模拟了不同冲击能量下的冲击响应过程。研究结果表明,T字型加筋板具有较高的抗冲击能力,模拟结果与实验测试结果吻合较好,该有限元模型具有较好的可靠性。In order to solve the problem of weak interlaminar shear resistance of T-shaped laminate composites,the weaving process of composite preform was reasonably designed,and the T-shaped fabric was woven by SGA598 small sample loom.The T-shaped fabric was prepared by vacuum assisted resin transfer molding(VARTM)process,and its impact resistance under low velocity impact was studied.The geometric and material models were established by using the finite element software ABAQUS to simulate the impact response process under different impact energies.The results show that the T-shaped stiffened plate has high impact resistance,and the simulation results are in good agreement with the experimental results.The finite element model has good reliability.
