Ultra high temperature ceramics carbon matrix composite

PIP is also a practical process to prepare ultra high temperature ceramic matrix composite, yet it has the same drawbacks of time-consuming and high cost. During the PIP process, a carbon fiber preform is infiltrated with a precursor solution and the preform filled with precursor is then cured. Finally, in an inert atmosphere, the cured preforms were pyrolyzed to form the ultra high temperature ceramic matrix (Sato et al. 1999). The precursors of the ultra high temperature ceramics are expensive and difficult to synthesize (Zhao et al., 2010). In addition, lots of cycles are usually needed to density a composite (Kohyama et al., 2000). 

The ceramic matrix of the ultra high temperature ceramic matrix composite is formed by the reaction of infiltrated metal with carbon in the porous C/C preform. The Gibbs free energies of the carbonized reaction at different temperatures are... 

RMI is an economic andqnicklabricationprocess for ceramic matrixcomposite. Recently, continuous carbon fiber reinforced ZrC, HfC and TiC composite have been successfully fabricated by RMI, which attracts much attention due to the promising applications in fabrication of ultra high temperature ceramic matrix composite. Even though great achievements have been reached, substantive further investigations should be made.
