    摘要:

    为了探究复合材料层合板在实际应用中因承受冲击载荷而造成的结构安全问题,本研究采用实验和仿真相结合的方法,首先探究冲头形状对复合材料层合板损伤机理的影响,然后结合不同冲击能进一步揭示层合板的承载力和能量吸收变化规律。结果表明,相同冲击能下,层合板的损伤范围和承载力随着圆锥头、半球头、平头依次增加;相应的层合板的临界穿透能量随着圆锥头、半球头、平头依次增大;冲头形状和冲击能对层合板的吸能能力有较大的影响。

    Abstract:

    In order to investigate the structural safety of composite laminates due to impact loads in practical applications, the influence of the impactor shape on the damage mechanism of composite laminate was analyzed simultaneously by experiment and simulation.Subsequently, the variation pattern of the load-bearing capacity and energy absorption of the laminate was further revealed considering different impact energy.The results show that under same impact energy, the damage range and bearing capacity of laminates present incremental change when impacted by conical, hemispherical and flat impactors.The critical penetration energy of laminates increases along using conical, hemispherical and flat impactors. The impactor shape and the impact energy have a greater influence on the energy absorption capacity of laminates.
