英文摘要	Carbon fibre reinforced SiOC composites (denoted as C-fibre/SiCfillers/SiOC) were prepared by slurry coating and polymer infiltration pyrolysis (PIP) process. Low viscosity liquid polysiloxane (PSO) and SiC powder were combined at a 1 : 1 weight ratio to produce a blend (S-PSO), which was employed as matrix source. Heat treated carbon fibre fabric was adopted as the reinforcement. The lamination process was determined on the basis of cure and rheology investigations on S-PSO. The effects of PIP cycles and temperature of heat treatment of the carbon fibre on the mechanical properties of C-fibre/SiCfillers/SiOC were examined. The results indicate that composites using carbon fibres annealed at 1700 degrees C as reinforcement reached a maximum flexural strength of 300 MPa after six PIP cycles. The resistance of the C-fibre/SiCfillers/SiOC composite to oxidation was also evaluated. Without any protective coatings, the composite retained 60% of its strength after oxidation at 800 degrees C for 3 h in a static air environment.
