摘要
SiC吸波纤维作为一种理想的高性能结构吸波复合材料的增强体,具有极其重要的应用价值。而要使普通先驱体法SiC纤维具备较好的吸波性能,必须对SiC纤维的电磁性能进行改性。介绍了SiC纤维电磁性能的几种改性方法,比较了各种方法的优缺点,分析了目前我国SiC纤维电磁改性研究中的不足。
As an excellent reinforcement material of high property structural radar absorbing composites, SiC fibers exhibit very important military values. But the electromagnetic properties of common SiC fibers fabricated with precursor polymer route should be modified if we want to use them as reinforcement material with good radar absorbing function. The modification means of the electromagnetic properties of SiC fibers were explained detailedly in the essay, and their advantage and disadvantage were compared. Then the shortcomings of the modification research of electromagnetic properties of SiC fibers at home were analyzed
