Abstract The thermal stability of the HPZ fibre in a chemical vapour infiltration (CVI)-processed SiC matrix composite was studied. The mechanical properties and fracture behaviour of the untreated and SiC-coated fibres after thermal exposure at different temperatures and atmospheres were characterized. The results show that, below 1000 °C, the strength degradation is negligible. However, severe degradation occurs at temperatures above 1000 °C due to the evolution of CO, SiO, and other gaseous species. Also, pyrolytic C-coating is needed to tailor the interfacial bond strength in the HPZ/SiC composite.
