摘要
作为先进复合材料的增强剂,高性能陶瓷纤维日益引起材料研究人员的广泛关注,并导致了纤维制备技术的不断发展。与早期的物理成形技术和化学气相合成技术相比,先驱体转化法具有易于制备细径纤维、组成结构可调的优点,是目前研究与开发的重点,其中溶胶-凝胶法比较适合制备氧化物陶瓷纤维,而有机聚合物转化法则比较适合制备非氧化物陶瓷纤维。
As the reinforcements for advanced composites, continuous ceramic fibers are attracting more and more attentions, which then results in the advancements of processing techniques. Compared with the physical and the chemical vapor techniques, precursor method has become the major route to continuous ceramic fibers, due to its advantage in making thin fibers with adjustable composition and structure. Among the precursors, sol-gel is converted mainly to oxide fibers and preceramic polymer is designed mainly for non-oxide fibers.
