Introducing MAX phases into SiC matrix composites: A review of preparation processes and performance improvement

Non-oxide continuous fiber-reinforced SiC matrix composites, with low density, high specific strength and modulus, are ideal for applications in thermal protection, braking systems, engines, and nuclear fusion reactors. However, the related properties of CMCs-SiC applied in these fields still need further improvement. Altering the interphase and matrix structure without changing the fiber is key to enhancing the performance of CMCs-SiC. Due to the unique composition and lattice structure, MAX phase modified CMCs-SiC composites have attracted extensive attention. However, the research of MAX phase modified CMCs-SiC composites is non-systematic and still need optimization. This review discusses the basic properties and fabrication processes of MAX phases, and their application in different structural units of CMCs-SiC. Introducing MAX phases into the material significantly improves composite properties, showing great promise for thermal protection and structural applications. Finally, we provide a perspective on the future directions of research in this field.
