铜基复合材料在火箭发动机上的应用，比铝基复合材料更有限，铜有两种性能吸引火箭发动机部件用它作为基材：与氧的相容性和高的导电性。与氧的相容性是气流循环发动机的氧化剂PMDs所必需的。在气流循环里，氧涡轮泵壳体和导管将直接与高温富氧气流接触。这些应用场合也需要高 Copper-based composites are more useful in rocket engines than aluminum-based composites. Copper has two properties that attract rocket engine components as substrates: compatibility with oxygen and high electrical conductivity. Compatibility with oxygen is required to circulate the engine’s oxidizer PMDs. In the gas flow cycle, the oxygen turbine housing and conduit will be in direct contact with the high temperature oxygen-enriched gas stream. These applications also need high
