And if the cable is exposed in the space environment for a long time, the cable is inconvenient and even dangerous in use and operation due to potential influences on the use safety caused by factors such as high-low temperature alternation, large irradiation dose, abrasion and the like, so that in some high-strength cables and application scenes related to outer space operation, a substitute of the steel cable is necessary to be searched.
In order to solve the above problems, studies have been made on using fiber ropes instead of steel wire ropes. For example, organic fiber materials such as ultra-high molecular weight polyethylene (UHMWPE), aramid, polyimide and the like are widely used in the fields of bulletproof protection such as military, public security, frontier defense, armed police and the like and civil fields such as high-performance rope nets and the like due to the advantages of low density, extremely high specific strength and specific modulus, good chemical stability, corrosion resistance and the like. However, although the organic fiber rope has higher tensile strength, the rope is soft and is not suitable for long-term outer space environment operation, so the rope made of the organic fiber rope has the defects of rigidity and irradiation resistance, and the rope net does not have the use requirement in high-performance rope nets such as aerospace and the like.
