Abstract Radar absorbing structures (RASs) contain a glass or aramid fiber-reinforced polymer (GFRP or AFRP) with carbon nanomaterials mixed with matrix. The main problem encountered by composite RASs is a non-uniformity in the performance due to agglomerated nanomaterials. In this study, RASs were developed that contained an AFRP with MWCNT-anchored para-aramid fibers to improve the performance uniformity. The topography of the MWCNT dispersion on the composites was analyzed by SEM. The reflection loss (RL) in the X-band range, dielectric properties, electrical properties and performance uniformity of the RAS composites were investigated. Finally, the optimum MWCNT concentration and incorporation method are presented.

使用多壁碳纳米管锚定芳纶纤维提高吸收性能均匀性的复合 RAS

摘要 雷达吸波结构 (RAS) 包含玻璃或芳纶纤维增强聚合物（GFRP 或 AFRP）以及与基体混合的碳纳米材料。复合 RAS 遇到的主要问题是由于纳米材料团聚导致的性能不均匀。在这项研究中，开发了包含 AFRP 和 MWCNT 锚定对位芳纶纤维的 RAS，以提高性能均匀性。通过SEM分析了复合材料上MWCNT分散体的形貌。研究了 RAS 复合材料在 X 波段范围内的反射损耗 (RL)、介电性能、电性能和性能均匀性。最后，给出了最佳的 MWCNT 浓度和掺入方法。
