Abstract

The invention relates to a low-temperature-resistant flexible rope for a high-altitude / space vehicle. The flexible rope comprises a load-bearing part, a heating fabric layer and a heat-insulating film layer, wherein the load-bearing part comprises central load-bearing woven fiber ropes and a first filling agent arranged among the woven fiber ropes; the heating fabric layer comprises electric heating materials and a second filling agent arranged among the electric heating materials, and the heating fabric layer covers outer sides of the woven fiber ropes; and the heat-insulating film layer covers the outer side of the heating fabric layer and is bonded to the heating fabric layer through an outer adhesive layer. According to the low-temperature-resistant flexible rope, problems about load bearing and heat insulation of high-strength ropes in high-altitude extremely-low-temperature environments are effectively solved, the reliability of the flexible rope under the extremely-low-temperature working condition is improved, the service life of the flexible rope under the extremely-low-temperature working condition is prolonged, the flexible rope is excellent in abrasion resistance, the inside heating efficiency of the rope is high, the whole structure of the flexible rope is easy to manufacture technically, and the extremely-low-temperature-resistant load-bearing performance is guaranteed powerfully.

Description

Technical field [0001] The invention relates to the technical field of low-temperature bearing ropes, in particular to a low-temperature resistant flexible rope for high-altitude / space vehicles and a manufacturing method thereof. Background technique [0002] High-altitude / space vehicles, such as space stations, spacecraft, stratospheric airships, high-altitude balloons, etc., have application advantages in many fields such as intelligence reconnaissance, communication relay, and climate observation. High-strength flexible rope is a necessary part of high-altitude / space vehicle, which plays a role of force transmission and fixation. However, due to the low temperature of the high-altitude / space environment, conventional ropes are easily brittle during the load transfer process, which causes the ropes to be easily broken and damaged under high-strength loads and cause safety accidents. Therefore, the research on the high-altitude / The development of space vehicles is of great sig...

AI Technical Summary

Problems solved by technology

However, due to the low temperature of the high-altitude / space environment, conventional ropes are prone to embrittlement in the process of load-bearing force transmission, resulting in the ropes being easily broken and damaged under high-strength loads and causing safety accidents. The development of space vehicles is of great significance

At present, the commonly used thermal insulation rope structure is a peripheral overall heating mode, and the flexibility of the rope after loading is reduced. The load-bearing rope is directly separated from the heating component, the energy consumption rate for heating is high, and the on-site assembly, docking and mounting process is complicated. Ropes and heating components are prone to cross interference
