Repeatable and flexible capture structure based on dielectric elastomer and shape memory polymer and method for capturing space debris

Abstract

The invention provides a repeatable and flexible capture structure based on dielectric elastomer and shape memory polymer and a method for capturing space debris. According to the repeatable and flexible capture structure based on the dielectric elastomer and the shape memory polymer and the method for capturing the space debris, the problems that traditional aerospace machines and motor driving capture structures are complex and large in weight are solved. The repeatable and flexible capture structure based on the dielectric elastomer and the shape memory polymer is mainly composed of the unfolding structure of a shape memory polymer composite material sheet layer, namely a three-wing type unfolding beam, and the dielectric elastomer. The structure constituted by the shape memory polymer composite material sheet layer is used for driving and controlling the capture structure to the designated spot, and the structure constituted by the shape memory polymer and the dielectric elastomer is used for capturing the space debris. The repeatable and flexible capture structure based on the dielectric elastomer and the shape memory polymer is simple in structure and high in reliability, and is applied to repeatable and flexible capture structures.
