Abstract

The invention provides a shape memory resin matrix composite material inflating support ring with an auxiliary unfolding device and an inflating unfolding method of the shape memory resin matrix composite material inflating support ring, belongs to the field of shape memory resin matrix composite material inflating support rings, and aims at solving the problem which exists in the unfolding process of the shape memory resin matrix composite material inflating support ring. The shape memory resin matrix composite material inflating support ring with the auxiliary unfolding device comprises an isolation layer added at the outer side of a force bearing layer, and the isolation layer is made from aramid fabric; auxiliary inflating support tubes are arranged at the outer side of convex angles and the inner side of concave angles of a Z-shaped folding state of a body, and are straight tubes made by adopting a flexible thin film material, the two ends of each auxiliary inflating support tube are bound at the corresponding two sides of the bending position of the body, and the distance between the two ends of each auxiliary inflating support tube and the body bonding position is smaller than the length of the auxiliary inflating support tube; all the auxiliary inflating support tubes are communicated a through flexible inflating conduit, and the body and the inflating conduit are provided with independent inflating end openings respectively. The shape memory resin matrix composite material inflating support ring with the auxiliary unfolding device is used for an inflating folding type space-borne antenna.

Problems solved by technology

[0002] Shape-memory resin-based composite materials can be folded arbitrarily after heating and softening. After cooling and solidification, they have the advantages of high rigidity and are not easily deformed by the space environment. At present, they have been used to make inflatable support rings. The space-borne flexible reflector antenna is made of shape-memory resin. It can be folded on the ground and compressed into a smaller volume, which is convenient for transportation. It can be heated and softened again when it is launched into a designated space area, and then inflated to expand, and then cooled and solidified to form a structurally stable antenna; During the ground folding process, the shape-memory resin-based composite inflatable support ring should be Z-folded around the central cylinder to form a shape close to a star, and then folded around the central cylinder and tightened and compressed. The folding range is large, close to 180 The crease is difficult to fully expand when entering the space and inflated, and it is heated and softened before inflating. After softening, it has a certain viscosity and the bend is prone to adhesion, which further affects the unfolding effect and even leads to failure.
