Abstract

To accomplish “Zero CO2 Emission society” development of alternative energy and reduction of energy dissipation are both necessary. SiCf/SiC composites are considered as enabling technology for both new advanced energy system and high efficiency system. A novel challenge, employing in situ fiber crystallization method, has been made in order to develop a new concept of SiC/SiC composites. The optimization of SiC/SiC fabrication process has been carried out through the observed microstructural defects. Worn behaviors and erosion resistance will be also discussed. The depending issues of prototype process were rather serious in this fabricating concept therefore the process optimization has been done on following issues. (1) Non-uniform fiber deformation caused by non-uniform PyC coating. (2) Excess pressure and stress concentration influencing fiber deformation ratio around 2.44. (3) Easy fiber detachment due to the weakened bonding energy and generation of aperture between fiber and interface. (4) Serious fiber volume contraction around 24.5% during the crystallization process in high temperature. (5) Generated pores due to interface cleavage.
