Problems solved by technology

[0004] However, in the truss structure, if the carbon fiber composite material integral multi-way joint is used, due to the interference between the length of the joint and the length of the branch pipe, most of the branch pipes cannot be inserted into the corresponding branch pipe joints

Embodiment Construction

[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] attached figure 1 There are five types of multi-way joints for carbon fiber composite materials, mainly including four-way joints, five-way joints, six-way joints, seven-way joints and eight-way joints.

[0021] attached figure 2 It is a schematic diagram of the composition of the carbon fiber composite material six-way joint. A carbon fiber composite multi-way joint, the multi-way joint includes a main pipe joint 1 and four branch pipe joints 2, the main pipe joint 1 and the branch pipe joints 2 adopt a two-petal structure, the The branch pipe joints 2 are distributed on the side wall of the main pipe joint and communicate with the main pipe joint 1 as required, and one of the branch pipe joints 2 is arra...

Abstract

The invention discloses a carbon fiber composite multi-way connector. The multi-way connector comprises a main through pipe connector and a plurality of branch through pipe connectors, wherein the main through pipe connector and the branch through pipe connectors all adopt a two-segment structure; the branch through pipe connectors are arranged on the side walls of the main through pipe connectorto communicate with a main through pipe as needed; the level surface and the vertical surface of an axis of each branch through pipe connector pass through the axis of the main through pipe connectorand are mutually perpendicular; an inclined angle is formed between the two adjacent branch through pipe connectors on the same side; a reinforcing plate rib is arranged at the connecting position ofevery two branch through pipe connectors and the connecting position of each branch through pipe connector and the main through pipe connector; and an annular strengthening layer is arranged at the periphery of each branch through pipe connector. According to the carbon fiber composite multi-way connector disclosed by the invention, the problem that when a complex truss structure is assembled, thebranch through pipe cannot be inserted into corresponding connectors at two ends can be solved; and besides, through annular strengthening of the main through pipe connector and the branch through pipe connectors, complex load requirements of the multi-way connector in a truss structure can be met.

Description

technical field [0001] The invention relates to the field of pipeline joints, and is mainly used in complex truss structures in the fields of aviation and aerospace, and in particular relates to a carbon fiber composite material multi-way joint. Background technique [0002] Aerospace vehicles have higher and higher requirements for lightweight and high-strength materials, and carbon fiber composite materials have a wider range of applications due to the above characteristics, and truss structures are one of them. [0003] The truss structure has the advantages of high net space value, easy to expand or assemble in space, and is limited by the size of the carrier's load compartment. It is especially suitable for applications in large-span or even super-long-span structures, such as solar UAV truss fuselage, airship support structure and satellite support structures. The narrow truss structure is a bar system structure composed of straight bars and joints. In practical engi...
