摘要：

为了获得一种轻质、高强且整体性良好的泡沫夹芯复合材料,并探究泡沫填充对中空复合材料弯曲性能的影响,将环氧泡沫填充至玻璃纤维间隔织物/环氧树脂复合材料中制备出一种泡沫夹芯复合材料,并对泡沫填充前后的复合材料的弯曲性能进行了测试。实验结果显示,泡沫夹芯复合材料的弯曲刚度可达14.92×10⁶N·mm²,其经向抗弯刚度提高了66.93%,纬向提高了106.08%。由此可知,环氧泡沫的存在可以明显地提高材料的抗弯性能。为揭示环氧泡沫在复合材料弯曲性能中的作用机理,结合显微镜图对泡沫填充前后复合材料的弯曲破坏模式进行了分析。结果表明,环氧泡沫在夹芯复合材料中不仅能起到传递载荷的作用,还能与柱纱发挥协同支撑作用,并能通过变形和破裂来吸收载荷和能量,致使复合材料抗弯性能显著提高。

Abstract:

In order to obtain a foam core composite material with light weight, high strength and good integrity, and examine the effect of foam filling on the bending properties of the composite material, a kind of foam core composite material was prepared by filling epoxy foam into the composite of glass fiber spacer fabric/epoxy resin, and the bending properties of the composite material before and after filling of foam were tested. The experimental results show that the bending stiffness of the foam core composite material is up to 14.92×10⁶N·mm², the warp-wise stiffness increases by 66.93%, and the weft-wise stiffness increases by 106.08%. It can thus be seen that the epoxy foam can significantly promote the bending performance of the material. In order to reveal the mechanism of epoxy foam in the bending properties of the composite material, and the bending failure modes of the material before and after filling of foam were analyzed through microscope images. The results show that the epoxy foam can not only transfer the load, but also play a synergistic supporting role with the column yarn, absorb load and energy through deformation and rupture. Therefore, the bending performance of the composite material is significantly improved.
