The compatibility of SiC fibers with aluminum was investigated. The SiC fibers made from an organosilicon polymer was used in the present study. The fiber specimens were aluminum-coated by vacuum evaporation and heat treated at temperatures 673 to 873 K for 90 ks, or 973 to 1373 K for 1.8 ks in an argon atmosphere. Then, the fiber specimens were tensile tested at room temperature.For the solid state aluminum, the SiC fibers showed no loss in tensile strength after the heat treatments at 673 to 773 K, but showed a slight degradation in tensile strength after the heat treatment at 873 K. For the liquid state aluminum, the SiC fibers showed a noticeable degradation in tensile strength after the heat treatments at temperatures higher than 973 K. However, the degradation in tensile strength was decreased in the solid and the liquid state by alloying Si with aluminum.
