Abstract

The invention provides a high-carrying-capacity embedded frame composite material structural slab which comprises a carbon fiber embedded frame, outer stressed skins, an aluminum honeycomb core and metal embedded parts, wherein the carbon fiber embedded frame comprises a hollow part, a frame with a U-shaped groove section and reinforcing ribs; the reinforcing ribs are connected with the frame with the U-shaped groove section; the aluminum honeycomb core is connected with the hollow part; the metal embedded parts are embedded in the U-shaped groove; and the outer stressed skins are arranged above and below the carbon fiber embedded frame respectively and are in cementation connection with the carbon fiber embedded frame. The high-carrying-capacity embedded frame composite material structural slab has the advantages of light weight and high carrying capacity; and the wide application of the structural slab provides the following benefits: the launching cost is reduced, the capability of a spacecraft for carrying high-capacity conduit heads is improved, and the perform of the spacecraft is improved.

Description

technical field [0001] The invention relates to a composite material structural board, in particular to a composite material structural board with a high bearing capacity embedded frame. Background technique [0002] The aluminum honeycomb sandwich structure plate is a common structure in the structure of artificial satellites, and is usually used as the main load-bearing component to install instruments and equipment such as stand-alone machines and loads on the satellite. The embedded frame can further improve its bearing capacity, making the whole board have higher strength and rigidity. [0003] In the past, the embedded frames of the aluminum honeycomb sandwich structural panels were mostly made of metal materials. While obtaining sufficient carrying capacity, the weight is relatively large, which cannot meet the requirements of light weight, high specific stiffness and high specific strength of the satellite structure at the same time.
