In this study, the main goal of this study was to understand the effect of carbon nanotube (CNT) additives on the elastic behaviors of textile-based composites. The materials have three phases: carbon fiber fabric, epoxy matrix, and carbon nanotubes. Different weight fractions of CNTs were used (0% as a reference, 0.3%). Mechanical tests were performed, such as tension and three-point bending beam tests. In addition, the composite material damages were examined in detail. The experimental results show that the samples with CNT carried 9% and 23% more axial tensile force and bending capacity on average than those with NEAT. Besides, it was understood that adding 0.3% by weight of MWCNT increases the tensile modulus by approximately 9%. Finally, the mechanical tensile and bending tests are supported by analytical solutions successfully applied in the literature.
在本研究中，主要目标是了解碳纳米管（CNT）添加剂对纺织基复合材料弹性行为的影响。这些材料有三个相：碳纤维织物、环氧基体和碳纳米管。使用了不同重量分数的碳纳米管（0%作为参考，0.3%）。进行了拉伸和三点弯曲梁等力学测试。此外，还详细检查了复合材料的损伤情况。实验结果表明，含有碳纳米管的样品平均比不含碳纳米管的样品多承受9%和23%的轴向拉力和弯曲能力。此外，据了解，添加0.3%重量的多壁碳纳米管可使拉伸模量提高约9%。最后，力学拉伸和弯曲测试得到了文献中成功应用的解析解的支持。
