SiC-SiC_f CMC manufacturing by hybrid CVI-PIP techniques: process optimisation

摘要

SiC-SiC_f ceramic matrix composites (CMC) are candidate structural mateial for fusion power reactor applications because of their favourable thermo-mechanical and low-activation properties. Among their different manufacturing techniques, present, the most employed ones are chemical vapour infiltration (CVI) and polymer infiltration and pyrolysis (PIP). These two techniques are based on the common principle of filling the porosity among the fibres with SiC resulting from precursor decomposition.
