Preparation of Carbon Fiber Reinforced SiC Matrix Composites by PIP Process

The precursor infiltration pyrolysis technology for preparation of ceramic matrix composites (CMCs) is both flexible and tailorable to shape and engineering requirements. During sintering process, PCS experienced an organic–inorganic transformation and acted as the bonding material between Carbon fiber. Compare to PCS, the ceramic conversion rate of PCS-DVB increased to 70-75%, the main reaction zone temprerature reduced to 400-800°C, which is in favor of protecting carbon fiber.
