摘要: 为探究聚酰亚胺纤维铺层角度对复合材料抗高速冲击性能的影响,制备了一系列不同铺层方式的聚酰亚胺纤维增强双马树脂基复合材料层合板,研究了铺层角度对复合材料损伤形貌、弹道极限速度和击穿吸能的影响。结果表明:不同铺层角度层合板内纤维各向异性越大,层合板变形量越大;[0/90]铺层具备最优抗高速冲击性能,非击穿情况下,[0/90]铺层的弹道吸能比[45/0/-45]铺层的弹道吸能效率提升61%,击穿情况下,[0/90]铺层击穿吸能比[30/0/-30]铺层击穿吸能提高68%;铺层角度影响冲击载荷在不同层间沿纤维轴向的传递,[0/90]铺层可以避免纤维横向剪切破坏,因此具备最优抗高速冲击性能。

Abstract: In order to investigate the effect of ply angle on anti-high speed impact properties of polyimide fiber reinforced composites, a series of polyimide fiber reinforced bismaleate composites laminates with different ply angle were fabricated. The effects of ply angle on the damage morphology, ballistic limit velocity and breakdown energy absorption of composites were studied. The results demonstrate that the greater the fiber anisotropy in laminates with different ply angles, the greater the deformation of the composite laminates; meanwhile, the results also indicate that [0/90] ply has the best high-speed impact resistance. Under non-breakdown condition, the ballistic energy absorption efficiency of [0/90] ply is 61% higher than that of [45/0/-45] ply, and under breakdown condition, the breakdown energy absorption efficiency of [0/90] ply is 68% higher than that of [30/0/-30] ply. Furthermore, the laying angle affects the transmission of impact loads along the fiber axial direction among different layers, [0/90] laying can avoid the transverse shear failure of fibers, so it has the best high-speed impact resistance performance.
