  • 摘要: 采用热压一次成型的工艺制备了曲面碳纤维增强树脂复合材料点阵夹芯结构,进行了三点弯试验探究了结构的弯曲破坏载荷与破坏模式。结果显示:结构的载荷位移曲线分为4个阶段,分别为线性阶段、损伤起始阶段、损伤演化阶段和失效阶段;破坏模式主要为面板压溃与节点失效。通过ABAQUS显示求解器建立了有效的弯曲和模态振动模型,得到弯曲破坏过程的失效模式、载荷位移曲线及结构振动模态与固有频率。讨论了不同参数(几何参数和材料性能)对弯曲和振动性能的影响,比较了不同边界条件对固有频率的影响。结果显示:相对密度(面板厚度、芯子直径)的增加会使结构的弯曲破坏载荷和固有频率增大,而芯子倾角ω的增大会使弯曲破坏载荷与固有频率的减小;材料的比刚度越大,固有频率越高。
