摘要
综述了用先驱体法制备陶瓷纤维、陶瓷基复合材料等的特点及其研究进展 ,针对制备陶瓷基复合材料基体的有机聚合物先驱体 ,提出了先驱体必须满足的理化特性和结构特征 ,同时还针对先驱体法高气孔率及高收缩率的不足 ,提出了 3个解决办法 。
The characteristics and development of ceramic fiber and ceramic matrix composites(CMCs) prepared by polymer precursor pyrolysis have been reivewed. By analyzing the requirements for ceramic matrix oriented precursors, suitable physical/chemical properties, and the structural characteristics were proposed. The disadvantages of precursor pyrolysis(high porosity and large shrinkage) were also discussed. Accordingly to overcome these drawbacks, three methods(synthesizing new precursors with high ceramic yields, adding inert filler, and adding active filler) were proposed. The characteristics and applications of active filler controlled precursor pyrolysis were introduced in detail.
