Damage Mechanism of Short Carbon Fiber Reinforced SiC-Based Composite

Abstract:

Article Preview

Short carbon fiber reinforced silicon carbide (SiC) composites were prepared with boron (B) and carbon (C) as sintering additives via pressureless sintering at 2150°C. The damage mechanism of fiber was investigated as following: (1) The carbon fiber was seriously physically damaged in the process of material mixing; (2) The chemical damage of the carbon fiber was happened in the reaction with matrix as the high sintering temperature; (3) Numerous cavities exist between the carbon fiber and the matrix leads to the weak interfacial strength.
