Fine reinforcing phase ceramic composite

WebApr 1, 2024 · Ceramic matrix composites (CMCs) are designed to overcome the main drawback of monolithic ceramics, namely their brittleness, and are constituently expressed as a continuous phase, or matrix, a distributed phase, commonly referred to as the reinforcing fibers, and also an interphase layer or coating layer between them. WebOne of the most interesting groups of materials, characterized by a combination of the properties of ceramics and metals that can potentially be used as a phase reinforcing the ceramic matrix, is the MAX phases [7,8,9,10,11]. The MAX phases constitute a large group of anisotropic crystalline materials.
