In this study, aramid fiber (AF)/phenolic resin prepreg was fabricated by impregnating low content carbon nanotube (CNT)‐reinforced phenolic resin with aramid fabric through a two‐roll pressing process. Both non‐functionalized and carboxylic‐functionalized CNTs (CNTs and CNTs‐COOH) were used for comparison study. For each of the formulations, composite laminate was made by a hot‐pressing process with a number of the prepregs stacked together. Mechanical properties and ballistic performance of the laminates and material failure mechanisms were evaluated and analyzed. Both non‐functionalized and CNTs‐COOH can effectively improve the mechanical and ballistic performance of the laminates. With CNTs‐COOH reinforcement, better results were achieved. As compared with the laminate without CNT reinforcement, 1.0 wt% CNTs‐COOH‐reinforced laminate showed 19.41%, 22.29%, and 45.83% improvement in tensile, flexural, and adhesion shear strength, respectively. The ballistic test results showed that the V50 and the specific energy absorption (SEA) were increased by 5.77% and 13.44%, respectively. The correlation between mechanical and ballistic performance of the composites was analyzed and conducted.

通过双辊压制工艺碳纳米管增强酚醛/芳纶织物复合材料具有优异的机械和防弹性能

在这项研究中，通过双辊压制工艺用芳纶织物浸渍低含量碳纳米管（CNT）增强酚醛树脂来制备芳纶纤维（AF）/酚醛树脂预浸料。非官能化和羧基官能化 CNT（CNT 和 CNT-COOH）均用于比较研究。对于每种配方，复合层压板都是通过热压工艺将许多预浸料堆叠在一起制成的。对层压板的机械性能和防弹性能以及材料失效机制进行了评估和分析。非功能化和CNTs-COOH都可以有效提高层压板的机械和防弹性能。通过CNTs-COOH增强，取得了更好的结果。与没有 CNT 增强的层压板相比，1.0 wt% CNTs-COOH 增强层压板的拉伸强度、弯曲强度和粘合剪切强度分别提高了 19.41%、22.29% 和 45.83%。弹道测试结果表明，V50和比能量吸收（SEA）分别提高了5.77%和13.44%。分析并进行了复合材料的机械性能和弹道性能之间的相关性。
