| 摘 要： | 将三维间隔连体织物泡沫夹层结构平压、剪切和三点弯曲载荷作用下的力学特性与三维间隔连体织物复合材料、传统泡沫夹层结构复合材料进行了对比分析，在此基础上，考察了芯柱高度、泡沫密度对复合材料平压、剪切、三点弯曲性能的影响。结果表明，三维间隔连体织物泡沫夹层结构复合材料承受平压载荷时，芯柱和泡沫存在协同效应；平压载荷作用下主要发生芯柱断裂破坏；随着芯柱高度增加，平压、剪切强度均减小；随着泡沫密度增加，平压强度近似呈指数增长。

| Abstract: | The mechanical characteristics of the foam filled 3-D spacer fabric composites under flatwise compressive,shear and three points flexural loads were compared with 3-D spacer fabric composites and foam sandwich composites,and the effects of pile height and foam density on the mechanical properties were investigated.The results indicate that there are synergy effects between pile and foam under flatwise compressive strength and fabric piles fractured under flatwise compression.The flatwise compressive and she... |
