C/SiC Ceramic Matrix Composites

C/SiC Ceramic Matrix Composites can replace refractory metals and high temperature alloys with at least 50% weight reduction, and as finite-life high-temperature anti-erosion structural materials, they can greatly save liquid rocket fuel and coolant, and improve thrust and damping performance. As a limited-life high-temperature anti-erosion structure material, it can greatly save liquid rocket fuel and coolant, and improve thrust and damping performance; C/C composites can be used as limited-life high-temperature heat-resistant structure material, which can greatly improve the safety and maneuverability of hypersonic vehicle. Safety and maneuverability, according to the assessment, under certain conditions, the line ablation rate of C/SiC Ceramic Matrix Composites is about half lower than that of C/C; polymer composites can be replaced as lightweight, high strength and long life space structure/functional materials, greatly improving thrust and damping performance. It can replace polymer composites as lightweight, high-strength and long-life space structure/functional materials, and greatly improve the stability of irradiation resistance and space environment performance.

Features of C/SiC Ceramic Matrix Composites:

(1) Lightweighting to improve the thrust of rocket engines focuses on increasing the operating temperature of engine components and reducing structural weight. The use of higher performance high temperature resistant lightweight composite materials (C/SiC Ceramic Matrix Composites) can reduce the mass share of the engine structure and improve the payload mass.

2) High strength, high modulus, good elongation, improve the self-oscillation frequency and stability of the structure;

3) High heat resistance, good ablative and scour resistance; can reach a temperature of 1650 ℃, flow rate greater than 300m/s above the work at least 1500S.
