Research abstract
A processing route to fiber-reinforced, SiC matrix composites which involves resin transfer moulding with a hydridopolycarbosilane preceramic polymer is proposed. This proprietary liquid resin thermosets to a rubbery solid at 200-400 C, permitting fabrication of free-standing, moulded parts. Pyrolysis at 1000 C gives near-stoichiometric SiC with 80-90% ceramic yield. Multiple infiltration, cure, and pyrolysis cycles would be used to prepare composites with less than 10% porosity. Test specimens for bend, fracture toughness, and interlaminar shear testing would be produced. The microstructure, mechanical properties, and thermal stability of the composites would be evaluated.
