In this study, glass fiber/epoxy resin/multi-walled carbon nanotubes (MWCNTs) were used to fabricate hybrid composites with biaxial warp-knitted fabrics. The biaxial warp-knitted fabrics were grafted with various amounts of MWCNTs and the hybrid composites were fabricated using the resin transfer molding (RTM) method, subsequently. The fabricated samples were subjected to compression after impact and Charpy impact tests. The hybrid composites exhibited higher compression after impact modulus and strength with 26 % and 17 % compared to the samples without nanotubes, respectively. Moreover, the MWCNTs integrated specimens showed 17 % improvement of Charpy impact strength against specimens without carbon nanotubes in 0 ° degree direction. Fracture surface analysis revealed lower number of cracks and shorter crack propagation lengths in the MWCNTs reinforced specimens. The improvement in mechanical properties of the hybrid composites can most likely be attributed to an increase in interfacial adhesion due to the presence of the carbon nanotubes.

在这项研究中，玻璃纤维/环氧树脂/多壁碳纳米管（MWCNT）用于制造双轴经编织物的混杂复合材料。用各种数量的MWCNT接枝双轴经编织物，然后使用树脂传递模塑（RTM）方法制造混合复合材料。在冲击和夏比冲击试验之后，对制成的样品进行压缩。与没有纳米管的样品相比，杂化复合材料在冲击模量和强度后分别显示出更高的压缩率，分别为26％和17％。此外，MWCNTs集成的样品相对于没有碳纳米管的样品在0°方向显示出夏比冲击强度提高了17％。断裂表面分析表明，在MWCNTs增强的试样中，裂纹数量较少，裂纹扩展长度较短。杂化复合材料的机械性能的改善很可能归因于由于碳纳米管的存在而增加了界面粘合性。
