Transmission shafts are the key parts in the deployable mechanism of antenna of satellite.They are long and thin, and endure the load of torture.The shafts must be very light.Steels were used to be used, but the mass is too large.Because of the merits of the composites,such as low density, high ratios of strength/ density and stiffness/ density, good fatigue durability, low thermal dilation and integration, they are suitable to be the material for the Transmission Shafts of satellite.This paper describes the research of material and process design to make the shafts.
