Abstract

An intelligent bamboo-shaped releasing mechanism made of a shape memory polymer composite material aims to solve the problem that when a traditional space expansion mechanism releasing mechanism is unfolded, impact is generated, and accordingly atmosphere environments are polluted. The diameter of an inner lower straight tubular section is smaller than that of an inner upper straight tubular section, an outer sleeve intensifier is sequentially composed of an outer upper straight tubular section, an outer taper tubular section and an outer lower straight tubular section from top to bottom, the diameter of the outer lower straight tubular section is smaller than that of the outer upper straight tubular section, the outer sleeve intensifier is arranged on an inner sleeve driver in a sleeving mode, an inner upper straight tubular section is located in the outer upper straight tubular section, an inner taper tubular section is located in the outer taper tubular section, an inner lower straight tubular section is located in the outer lower straight tubular section, the upper end face of the inner upper straight tubular section is lower than that of the outer upper straight tubular section, the lower end of the inner lower straight tubular section is exposed out of the outer lower straight tubular section, the inner wall of the inner sleeve driver and the inner wall of the outer sleeve intensifier are each coated with a thermoelectric film, and the inner sleeve driver and the outer sleeve intensifier are both made of the shape memory polymer composite material. The mechanism is used for space expansion mechanisms in the field of aerospace.

Description

technical field [0001] The invention relates to a polymer composite material release mechanism, in particular to an intelligent bamboo-shaped shape memory polymer composite material release mechanism. Background technique [0002] The release mechanism of polymer composite material has played a release role in space deployment mechanisms such as artificial satellite antennas, solar energy deployment battery arrays, space deployable hinges, and rocket separation. The release mechanism of the traditional space deployment mechanism is mainly an explosion bolt, which ensures sufficient and reliable explosion separation while ensuring sufficient mechanical strength, and under ideal conditions, there should be no explosion fragments. The application of the explosion bolt in the release of the space deployment mechanism has a system It is complex, heavy, and relatively low reliability. When the space is released and the structure is expanded, an impact occurs, and the explosion fra...
