Recent Advances in Interface Engineering for Enhancing the Performance of Ceramic Matrix Composites

Due to their exceptional thermal stability, oxidation resistance, and mechanical strength, ceramic matrix composites (CMCs) are required in high-temperature, chemically aggressive, and mechanically demanding environments, where traditional materials often fail. These attributes make CMCs well-suited for demanding applications in aerospace, energy, and industrial sectors, where they withstand extreme heat, mechanical stress, and chemical exposure, playing a crucial role in areas such as aircraft engines, space exploration, and energy conversion systems. Therefore, the paper reviews recent progress in interfacial modification strategies for CMCs, summarizing key findings via a comparative analysis of experimental results and a meta-analysis of relevant literature. The results indicate that innovative interface engineering techniques like fiber coating, interphase tailoring, chemical vapor infiltration, and thermal treatment under controlled atmospheres, notably enhance the thermal resistance and fracture toughness of CMCs. In addition, it scrutinizes the existing limitations of current engineering strategies and provides valuable insights into future trends in interface engineering for CMCs.
