Research on the Performance of Carbon Fiber Reinforced Inorganic Polymer Composite

Abstract

This paper introduced a novel carbon fiber reinforced inorganic polymer non-sintering ceramic composite. It is composed of a low temperature curing material system, and can be manufactured by a traditional process for resin matrix composites. According to relevant test standards, the performances including the mechanical properties, the coefficient of linear expansion and the ablation ration were studied. The results show that the tensile strength is more than 150MPa, the bending strength is more than120MPa, the average coefficient of linear expansion is less than 0.213×10-6/°C(between room temperature and 800°C), the ablation ratio is less than 0.0715mm/s, the mass retention ratio after ablation at 1000°C for 600s is less than98%. The composite could be used for the micro ablative in large area thermal protection such as national defense, aircraft and so on.
