Effect of Infiltration Temperature on the Composition and Mechanical Property of RMI C/C-SiC Composite

Abstract:

C/C-SiC composites were prepared by reactive melt infiltration process at different temperatures. The composition, microstructures and mechanical properties of the composites were investigated. The results showed that infiltration temperature could affect composite’s properties through regulating the chemical composition and interfacial bonding strength of the composites. The C/C-SiC composite prepared at 1650°C exhibited the relatively highest performance with density of 2.24 g·cm^-3 and SiC content of 31.44 vol.%. The flexural strength and the fracture toughness were 238MPa and 10.04 MPa·m^1/2, respectively.
