过去 60 年来，已经开发出多种类型的陶瓷纤维。其中，碳纤维已发展成为涉及纤维增强塑料和轻质耐热复合材料的巨大市场。此外，SiC基纤维的许多改进也已实现。具有优异耐热性的 SiC 多晶纤维（Hi-Nicalon S 型和 SA 纤维）已被开发出来，并且其许多应用也已得到检验。还生产出了一种坚韧的导热碳化硅基陶瓷（SA-Tyrannohex），该陶瓷由高度有序、密堆积的六角柱状纤维结构组成。最近，利用含有低分子量添加剂的前体聚合物，可以将其转化为目标功能材料，还开发了具有梯度表面层的优异功能陶瓷纤维。本章描述了这些纤维材料的代表性特性及其预期应用。
Many types of ceramic fibers have been developed over the last 60 years. Of these, carbon fiber has grown into a large market involving fiber-reinforced plastics and lightweight heat-resistant composites. In addition, many modifications of SiC-based fibers have been achieved. SiC-polycrystalline fibers (Hi-Nicalon Type S and SA fiber) with excellent heat-resistance have been developed and their many applications have been examined. A tough, thermally conductive SiC-based ceramic (SA-Tyrannohex) composed of a highly ordered, close-packed structure of hexagonal columnar fibers has also been produced. Recently, using a precursor polymer containing low molecular weight additives, which can be converted into an objective functional material, excellent functional ceramic fibers with gradient surface layers were also developed. In this chapter, representative properties of these fibrous materials and their expected applications are described.
