Carbon fiber reinforced aluminum matrix composites （Cf/Al） have many advantages, such as high specific strength, high specific stiffness, low coefficient of thermal expansion and high thermal conductivity. In view of the application re- quirements in space environmnet, the researches of Cf/Al composites are summarized, with the structural strength and stiffness of Cf/Al composites chamber components discussed. Researches show that the Cf/Al composites have a longitudinal modulus of 230GPa and a bending strength of 1400MPa, and excellent space irradiation resistance. The structural strength and stiffness of the cylinder chamber component made of Cf/Al composites are 3 and 3.5 times higher than those of Mg component with a twice wall thickness. Cf/Al will provide a technical support for the miniaturization and light weight design of the new generation spacecrafts.
