The SiC fiber reinforced β21S composites (SiCf/β21S) were prepared by foil–fiber–foil (FFF) method. The foils were obtained by cold rolling and annealing treatment, and the fiber cloth was obtained by computer controled filament winding machine. The consolidation process of FFF was calculated by finite element analysis software, and the optimum process parameters were determined. SiCf/β21S composites were prepared under the optimum conditions, the hot isostatic pressing process parameters were 830℃ , 860℃ /120MPa/2h, and then heat treated in vacuum environment at varied temperature for 0h, 9h, 25h, 49h. The microstructure of SiCf/β21S composites and metal matrix were analyzed after the vacuum heat treatment, the microstructure evolution and kinetics of interfacial reaction layer were investigated. The ribbed skinning part of SiCf/β21S composite was fabricated by the combination of foil–fiber–foil method and hot isostatic pressing process. The microstructure and properties of SiCf/β21S composite part were tested and analyzed.
