Preparation of Cf/SiC Composites by Liquid Silicon Infiltration

摘要：

　　The Cf/SiC made from carbon fiber preforms infiltrated by phenol resin,pure carbon slurry and aqueous C/SiC slurry showed different binding strength between carbon fiber and SiC matrix,thus influenced the fracture behavior of the composite.The fracture toughness of the Cf/SiC composites with the value of 9.82MPa·m1/2,improved remarkably compared with reaction-bonded silicon carbide (RBSC).But the flexural strength was less than 100 MPa,because of the existence of considerable amount of pores in C/SiC composites.
