Abstract
An erosion-resistant and ablation-resistant material suitable for oxygen-enriched environments, including modified high-temperature resistant phenolic resin: 30-50 parts; carbon fiber: 2-5 parts; aramid fiber: 1-5 parts; silicon carbide: 0-30 parts ; High temperature resistant oxide filler: 10-25 parts. The anti-scouring and ablation-resistant material of the invention has excellent anti-scouring and anti-ablation properties, high strength, good oxidation resistance, and can meet the working requirements of the air-breathing rocket engine whose working time exceeds 400s.
Description
technical field [0001] The invention relates to an erosion-resistant and ablation-resistant composite material used in an oxygen-enriched environment, such as an air-breathing engine shell and an engine nozzle, and belongs to the field of rocket engine thermal protection. Background technique [0002] Anti-erosion and ablation-resistant materials are commonly used in rocket engines, including the nozzle and metal casing of the engine. During the working process of the rocket engine, high-temperature gas of several thousand degrees will be produced, accompanied by a large amount of metal particles such as: magnesium, aluminum, boron, etc., the gas and particles will cause severe ablation and erosion of the metal wall, in order to prevent the metal shell of the engine from Body burn-through requires a layer of anti-scouring and ablation-resistant materials to be attached to the inner wall of the engine to protect it. At present, the commonly used thermal insulation materials ...
