Ceramic matrix composites (CMCs) generally consist of ceramic fibers or whiskers in a ceramic matrix. CMCs are referred to as inverse composites, which is to say that the failure of the matrix is lower than the failure strain of the fibers, whereas it is the reverse in most polymer or metal matrix composites .
By combining different ceramic matrix materials with suitable fibers, new properties can be obtained and used in interesting technical fields .
In ceramic matrix composites, the ceramic reinforcement essentially provides toughness to an otherwise brittle ceramic matrix. On the other hand, the characteristics which are desired from ceramic matrix composites include high-temperature stability, high thermal shock resistance, high hardness, high corrosion resistance, light weight, non-magnetic and non-conductive properties, and versatility in providing unique engineering solutions .
Reaction bonded silicon carbide (RBSC) ceramics which typically involves α-SiC, β-SiC and Si phases are attractive materials for high-temperature heat exchanger, piping, light armor and optical mirror, due to their low sintering temperature, near-net shaping, full densification .
