在这一章中，我们讨论了CMC中界面的作用，特别强调了纤维/基体界面的力学，因为它与称为韧性的有点难以捉摸的性质有关。第五章讨论了界面的一般特征及其在复合材料中的重要性.现在，我们看看在CMC中定制该界面的主题，以期在这些材料中获得增强的断裂韧性。我们给出了一些CMC中的界面结构的例子，简要回顾了不同类型的CMC中的韧性问题，然后详细分析了纤维增强陶瓷基复合材料的增韧机制，因为增韧在CMC中的重要性。
In this chapter, we discuss the role of interface in CMCs with special emphasis on mechanics of the fiber/matrix interface as related to that somewhat elusive property called toughness. We discussed the general features of interface and its importance in composites in Chapter 5. Now we look at the subject of tailoring this interface in CMCs with a view to obtaining an enhanced fracture toughness in these materials. We give some examples of the interface structure in some CMCs, briefly review the topic of toughness in different types of CMCs and then analyze in some detail the toughening mechanisms in fiber-reinforced ceramic matrix composites because of the importance of toughness enhancement in CMCs.
