Multi-walled carbon nanotubes (MWCNT)/carbon fiber fabric multiscale hybrid materials were prepared by grafting MWCNT on carbon fabric surface via heating grafted method to improve the mechanical and tribological properties of phenolic resin composites. Field emission scanning electron microscopy, Raman spectrometer, and X-ray photoelectron spectroscopy were used to analyze the surface properties of carbon fiber. The results shown that the tensile strength of composites modified by 0.15 wt% MWCNT was 38% higher than that of unmodified composites. The wear rates decreased from 3.31 × 10−14 m3 (N·m)−1 for unmodified composites to 0.68 × 10−14 m3 (N·m)−1 for 0.15 wt% MWCNT reinforced composites. The reason was that the uniformly distributed MWCNT could increase interface interaction and mechanical interlocking between carbon fiber fabric and resin matrix.

多壁碳纳米管/碳纤维织物多尺度杂化材料用于改善酚醛树脂复合材料的机械和摩擦学性能
采用加热接枝法在碳织物表面接枝多壁碳纳米管(MWCNT)/碳纤维织物制备多壁碳纳米管(MWCNT)/碳纤维织物多尺度杂化材料，以提高酚醛树脂复合材料的力学和摩擦学性能。采用场发射扫描电子显微镜、拉曼光谱仪和X射线光电子能谱分析碳纤维的表面性能。结果表明，经 0.15 wt% MWCNT 改性的复合材料的拉伸强度比未改性复合材料高 38%。磨损率从未改性复合材料的 3.31 × 10 -14 m 3 (N·m) -1降至 0.68 × 10 -14 m 3 (N·m) -1对于 0.15 wt% MWCNT 增强复合材料。原因是均匀分布的 MWCNT 可以增加碳纤维织物和树脂基体之间的界面相互作用和机械互锁。
