Abstract

A disclosed lightweight multi-functionalization interlayer-structure plate comprises an upper panel, a lower panel and a multihole core plate arranged between the upper panel and the lower panel; the upper panel is provided with multiple electric connectors; and the multihole core plate is inside provided with multiple reinforcing frames and a heat pipe, each reinforcing frame is inside provided with a cable, and each cable is fixedly connected with one electric connector. The invention also provides a corresponding manufacture method. The lightweight multi-functionalization interlayer-structure plate integrates an electronic system in a spacecraft supporting structural plate so as to weed out electronic equipment cabinets and cable connection, enables installation space of spacecraft loads, such as antennas, optical cameras and the like to be maximized, and lightens the satellite integral weight and accelerates assembling of the whole satellite.

Description

technical field [0001] The invention relates to a light-weight multi-functional interlayer structural plate for satellites and a manufacturing method thereof, belonging to the technical field of aerospace engineering. Background technique [0002] The honeycomb sandwich structure is a special type of composite material that uses carbon fiber or glass fiber sheet as the skin and honeycomb material as the sandwich layer. It has the advantages of light weight, high strength and high rigidity. Therefore, it is often used as a structural part with large size and high strength requirements. The structural plate for satellite platform is one of its typical application products. The traditional structural board is to embed heat pipes in the structural board to realize the combination of machine and heat. However, considering the requirements of each functional module of the satellite subsystem in terms of power supply, communication, and data storage, the electronic system (includin...
