Abstract: To solve the contradiction between capability of bearing outer loading and mass coefficient in solid rocket motor, three kinds of cases were made differently with F12 fiber/4304 epoxy ,S-2 glass fiber/4304 epoxy, and their interweave fibers /4304 epoxy .By the torsion and axial compression experiments, the shearing and axial compression properties of the three kinds of cases were obtained, and their weight was measured at the same time. The results indicate that by using interweave fibers composite case , capability of bearing outer loading and request of mass coefficient can be met in solid rocket motors at one time.
