Carbon fiber reinforced aluminum matrix composites (Cf / A) l with high specific strength, high specific stiffness, low thermal expansion, good dimensional stability and other excellent performance. According to the application requirements of space environment, the research results of Cf / Al composites are summarized, and the structural strength and structural rigidity of Cf / Al composites are analyzed. The results show that the composite has a longitudinal elastic modulus of 230GPa and a flexural strength of 1400MPa, which possesses excellent environmental performance in irradiation-resistant space. The structural rigidity and structure of the magnesium alloy pod, which is twice as thick as the wall thickness of the composite cylindrical pod member, High strength 3 times and 3.5 times. Carbon fiber reinforced aluminum composites provide technical support for the miniaturization and lightweight design of a new generation of spacecraft.
