[Material selection and structural design of simulated space module for field].
OBJECTIVE
To select the suitable material for the structure of simulated space cabin to meet the special requirements which the unitary metallic material cannot do.


METHODS
The structural material was selected through comparison between the mechanical properties of fiber reinforced plastics (FRP) and a few conventional metallic materials. The content and arrangement of the fibers in the composite material were suitably designed according to load condition and structural shape of the cabin.


RESULTS
High strength and high stiffness, light weight, anti-fatigue and shock proof were achieved for the whole module structure. It meets the medical and hygienic standard for hazardous gases.


CONCLUSIONS
The structural design of fiber glass reinforced plastics composite module was proved to be successful. It reduced the weight of the module body, and increased the strength and toughness of the whole module.
