摘要
采用箔-纤维-箔方法制备了SiC纤维增强β21S复合材料(SiC_f/β21S),其中箔材采用冷轧+退火处理的方法获得,纤维布采用数控纤维缠绕机获得。采用有限元分析软件对纤维布与箔材的复合过程进行了计算,确定了较佳的制备工艺参数。在较佳的工艺参数条件下制备SiC_f/β21S复合材料,其中热等静压工艺参数为830℃、860℃/120MPa/2h,然后在不同温度条件下,进行0h、9h、25h、49h的真空热处理,对SiC_f/β21S复合材料的纤维/基体界面和基体微观组织进行了分析,研究了界面反应层的微观组织演变和动力学长大规律。采用箔-纤维-箔方法与热等静压成型工艺相结合的方法,在最佳工艺参数条件下制备了SiC_f/β21S复合材料蒙皮结构,并对其组织和性能进行了测试分析。
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 var- ied 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.
