Embodiment Construction

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0036] see figure 1 and figure 2 , a composite material space truss structure, including:

[0037] The wall thickness is a square pipe with a three-layer structure, in which the inner layer 4071 and outer layer 4073 are made of 12K carbon fiber, and the middle layer 4072 is made of 50K large tow carbon fiber.

[0038] The angle between the 12K carbon fiber weaving angle of the inner layer 4071 and the central axis of the square pipe is ±45°, the angle betwe...

Abstract

The invention relates to a composite material space truss structure and a preparation method based on a curing forming mold, relates to the technical field of space stations, and solves the technicalproblems that in the prior art, a truss structure of a space station is formed in a multi-round-pipe mode through equal-tension winding, the structural form is single, the length of the structure is limited by the specification of a winding machine, short-pipe and short-rod splicing is usually achieved through a metal adapter, the damage risk of composite material bonding tapping is increased, andthe effective load is reduced. The composite material space truss structure is technically characterized by comprising a square pipe body with the wall thickness being of a three-layer structure, 12Kcarbon fibers are adopted in an inner layer and an outer layer, and 50K large-tow carbon fibers are adopted in a middle layer. The truss structure has the beneficial effects of avoiding complex splicing and assembling of the short pipes and the short rods, reducing the risk and the weight of the connecting ends, further improving the effective load and improving the truss foundation for a large space structure.

Description

technical field [0001] The invention relates to the technical field of space stations, in particular to a composite material space truss structure and a preparation method based on a solidification forming mold. Background technique [0002] As the basic structure of the space phase station, the truss structure transmits and bears the load, and also provides the installation foundation for various components and other payloads. At present, the truss structure of the space station is in the form of multi-round tubes, which are formed by equal tension winding. Risk of bore damage and reduced payload. Contents of the invention [0003] The present invention aims to solve the multi-round tube form of the truss structure of the space station in the prior art. It is formed by equal tension winding and has a single structural form, and the structural length is limited by the specifications of the winding machine. The short tubes and short rods are often connected by metal adapte...
