提出了一种空间再入环境模拟实验方法，以研究碳/碳化硅复合材料及其性能。通过控制热环境和应力环境，模拟了再入大气层的环境。热环境设有高焓燃烧室，温度范围为600°-1800 ° C，氧分压为10-30 kPa。该应力环境可实现加载和旋转两种效果，最大扭矩为150 N·m，最小转速为32 rpm。通过这种方法，可以在再入过程中对碳/碳化硅复合材料进行多用途测试，例如热连接、应力氧化、蠕变和摩擦行为。
An experimental simulation method of space re-entry environment was presented to investigate a carbon/silicon carbide composite and the effect on its properties. The re-entry environment is simulated by controlling the thermal environment and the stress environment. The thermal environment is provided with a high enthalpy combustion chamber with a temperature range of 600°–1800°C and a partial pressure of oxygen of 10–30 kPa. The stress environment can realize both loading and rotating effects with a maximum torque of 150 N·m and a minimum rotation velocity of 32 rpm. Multipurpose testing of a carbon/silicon carbide composite during re-entry can be achieved by this method, such as hot joining, stress-oxidation, creep, and friction behavior.
