  • In order to meet the requirements of light weights, high specific strength and high specific moduli for a space payload, the advantages and disadvantages of the engineering materials used in the supports of the space payload were analyzed, and the feasibility of the application of the carbon/epoxy composites to the suppors structures was explored. The design methods of the carbon/epoxy composites were introduced by the actual application in space fields. Finally, a carbon/epoxy composite structure was designed and fabricated to support a 80 kg weight payload and to undergo both sine and random vibration tests. Experimental results indicate that the structure can resist the acceleration of the random vibration tests in a structural basic frequency of 103.6 Hz successfully, while the mass has reduced almost 30% as compared with that of the structure made by Al alloy materials. It is shown that the carbon/epoxy composites can be used as the support structures of the space payloads.
