Research progress on meso-structure and mechanical properties of SiCf/SiC textile composites

SiCf/SiC textile composites have enormous development potentials in the field of aerospace hot-end component owing to their strong structural design, low density, excellent mechanical properties, high-temperature resistance and oxidation resistance. However, there are few researches on the preparation technology, performance and meso-structure of SiCf/SiC textile composites. In the long run, it is still the research direction that must be carried out in country’s aviation engine manufacturing. In this paper, the research status of SiCf/SiC textile composites in recent years is introduced from three aspects: meso-scale structure, mechanical properties and numerical simulation. The research status of SiCf/SiC textile composites in recent years is summarized, and the basic research of domestic and foreign applications is comprehensively compared. Although the domestic preparation technology has made great progress and reached the international advanced level, it is still in its infancy in terms of component assessment and verification and application. Only by optimizing on the basis of the comprehensive balance of reliability, durability, process and performance, and realizing the synergy of materials and processes, structure and design, can breakthroughs be made in the future development of aeroengines.
