Abstract:
In order to validate the effects of restraint layer material on mechanical properties of spacesuit joints,application and development trend of typical restraint layer materials were studied.Based on the design requirement of restraint layer material for spacesuit joint functional analysis,choosing polyamide fiber and polyarylester fiber with same weaving process,two kinds of restraint layer fabrics were obtained.Effects on spacesuit joint performance were studied by comparison test on material mechanical properties and typical joint mobility with both fabrics.The results indicate that the characteristic of polyarylester with high strength and low elongation has advantage on compression and ergonomic support.The high modulus of polyarylester can provide creep resistance for spacesuit joints in the condition of periodic inflating and working,which can perform structure stability in life cycle.The high stiffness of polyarylester can reduce the thickness of fabric,which can improve hysteresis and reduce joint resistance on spacesuit joints but also interfere smoothness in the process of joint motion.The results can provide references for the design on spacesuit joints and the selection on restraint layer materials.
