为了研究异形截面碳纤维复合材料的吸波性能,采用SEM、XRD及XPS等测试技术,对异形截面聚丙烯腈基碳纤维(ICF)和T300碳纤维的表面形貌、组织结构及化学组成进行了研究.结果表明:ICF的截面形状成近似正三角形,截面异形度为13.16%;与树脂基体可以形成较强的界面作用;其力学性能与T300接近,可作为结构材料的增强体使用.分别采用四电极法、网络法和雷达散射截面(RCS)法研究了2种纤维增强的复合材料的电磁性能和吸波性能.结果表明:ICF的电阻率比T300大;在高频电磁波作用下,ICF复合材料的介电常数虚部(ε″)及损耗角正切(tanδ)均比T300复合材料大;其复合材料对频率在16 GHz左右的电磁波的反射率为-8 dB.通过研究,异形截面碳纤维复合材料同时具有承载和吸波的作用,将是一种有前途的结构吸波材料.
