specific Embodiment approach 1

[0005] Specific implementation mode one: (see Figure 1-Figure 2 ) This embodiment consists of at least three inflatable expansion tubes 1 and several heat-curable support rods 2. The inflatable expansion tube 1 is composed of an inner lining layer 1-1 and a heat-curable layer 1-2. The heat-curable layer 1-2 Set on the outer surface of the inner lining layer 1-1, the inner lining layer 1-1 is a polyimide plastic film or rubber film, the heat-curable layer 1-2 is a pre-impregnated epoxy resin fabric; the heat-curable support rod 2 Fixedly connected between every two inflatable expansion tubes 1, the heat-curable support rod 2 is a carbon fiber rod pre-impregnated with epoxy resin. The epoxy resin prepreg requires less energy for curing, and has the advantages of excellent mechanical properties, good insulation performance, and good corrosion resistance after thermal curing. The thermally curable layers 1-2 and thermally curable support rods 2 described in this embodiment Epoxy...

specific Embodiment approach 2

[0006] Specific implementation mode two: (see Figure 1-Figure 3 ) The difference between this embodiment and the first embodiment is that it adds a rigid connection sleeve 3 and a pin 4, and the rigid connection sleeve 3 is set on the outside of the inflatable expansion tube 1 and fixed on the inflatable expansion tube 1. The heat-curable support rod 2 The connection of the rigid connection sleeve 3 is fixed with a support rod installation tube 3-1, and the support rod installation tube 3-1 is provided with a radial pin hole 3-1-1, and the plurality of heat-curable support rods 2 The two ends of each are respectively placed in the support rod installation tube 3-1 on the rigid connection sleeve 3 and glued together, and the pin 4 is placed in the radial pin hole 3-1-1 on the support rod installation tube 3-1 and passed through The ends of the struts 2 can be cured with heat. Other compositions and connections are the same as in the first embodiment. Due to the addition of t...

Abstract

The present invention relates to one kind of inflating expanded truss for outer space use. The inflating expanded truss includes at least three inflating expanded pipes and several thermosetting support rods. Each of the inflating expanded pipes consists of one inner lining layer and one outer thermosetting layer. Each of the thermosetting support rods is connected between two inflating expanded pipes. After being launched to preset space orbit, the inflating expanded pipes are inflated and the truss structure is expanded to fixed shape and hot cured via absorbing sun radiation, so as to obtain designed rigid truss. The present invention needs no outer space assembling and has the advantages of small folded volume, high expanding reliability, light weight, etc and thus wide aeronautic and astronautic application foreground.

Description

technical field [0001] The invention relates to a truss technology applied in space. Background technique [0002] The advent of the space station marks a new stage in the large-scale development of space resources by mankind. This kind of space building that can be used by many astronauts to live and work for a long time is like an artificial heavenly palace. It relies on the transporter to provide daily necessities, so that it is no longer a dream for human beings to live in space; It is an ideal auxiliary platform for various research work such as scientific research, space production and on-orbit service. At present, mechanically unfolded rigid truss structures are widely used in space. It is very difficult to construct super-sized truss structures in the weightless environment of space. On the space orbit, astronauts need to go out of the cabin for assembly many times, so the cost is high and the risk is high. Contents of the invention [0003] In order to solve th...
