Mechanical Properties of Short Carbon Fiber-Reinforced SiC-Matrix Composites and Correlation to Fibers

摘要：

　　PAN and Pitch short carbon fiber-reinforced SiC matrix composites were fabricated by using a melting infiltration technique.The microstructure of the resulting composites was characterized by scanning electron microscopy.The flexural strength of the composites was measured at room and high temperatures.The thermal conducitivity of the composites were evaluated.Effects of fibers on mechanical properties and thermal conductivity were assessed.The experimental results showed that the silicification of fibers during siliconizing was prevented due to the presence of barrier layer on the surface of fiber.Also,flexural strength and thermal conductivity depended on fibers used and content of fibers.
