Cobweb capture structure based on intelligent composite materials

Abstract

The invention provides a cobweb capture structure based on intelligent composite materials. The cobweb capture structure includes a cobweb structure woven by warps made of a shape memory polymer composite material and wefts made of a linear fiber driver and high-temperature nylon, and having a closed end and an open end. The open end and the weft at the middle of the cobweb structure are the linear fiber driver. The wefts at the other positions of the cobweb structure are the high-temperature nylon. The linear fiber driver is thermally-treated wound high-temperature nylon having a surface coated with silver paste. Each warp is uniformly covered with electric heating sheets spaced apart from one another in the longitudinal direction. Each warp at the open end of the cobweb structure is connected with an auxiliary cable. Adjacent warps and wefts are independent of each other. The cobweb capture structure based on intelligent composite materials according to the present invention can be autonomously driven and reused, has certain rigidity, and can racemize and orbit transfer a captured object.

Description

technical field [0001] The invention belongs to the field of aerospace, and in particular relates to a spider web capture structure and a capture method based on intelligent composite materials. Background technique [0002] At present, among the many satellites launched by humans, most of them have ended their service, but due to the immature early technology, it is impossible to realize the recovery and destruction of satellites. On February 10, 2009, the American communication satellite "Iridium 33" collided with the Russian abandoned satellite "Cosmos 2251". These fragments have lost the restraint and drive of the satellite, posing a huge threat to satellites and space stations of various countries. However, not only satellites collided, many satellites were also hit by other space materials and produced a large amount of space debris. [0003] Space debris, commonly known as space junk, is the waste produced by human space activities, generally consisting of debris an...

Problems solved by technology

However, due to special reasons, when the satellite loses its ability to control itself or the ground cannot get in touch with the satellite, the out-of-control satellite becomes a greater hidden danger in the low-Earth orbit. At present, some rope net structures take it into the cemetery orbit after capture to reduce the near-Earth orbit. space pressure in earth orbit

[0005] In order to solve the problem that the existing rope net structure basically relies on the driving effect of the mass block, the springback effect of the mass block and the net, the spin of the net cannot be captured smoothly when the spin is unfolded, and the net is affected by external forces and deviates, which leads to malfunction and cannot be adjusted. Weaknesses such as capturing objects for derotation processing, which cannot be reused, and cannot perform orbit transfer tasks, etc., provide a self-driven, reusable, with a certain degree of rigidity, and can perform derotation processing and orbit transfer on captured objects.
