Microstructure and Mechanical Properties of C/SiC Composites Prepared at Low Temperatures

摘要：

　　2D-C/SiC composites with high performance were prepared at temperatures as low as 900 ℃.The flexural strength of the composites reached 329.61MPa,the same level as the composites prepared at 1200℃,and shear strength and fracture toughness were 32.14MPa and 14.65MPa·m1/2,respectively.The microstructure and mechanical properties of the composites after heat-treatment at 1600℃ were also investigated to determine the potential applications at high temperature.
