Abstract

The invention discloses a composite material sandwich plate for a floating body structure and a floating body. The composite material sandwich plate for the floating body structure comprises a first high-alkali-resistant glass fiber cloth layer, a second high-alkali-resistant glass fiber cloth layer and a core layer, wherein the first high-alkali-resistant glass fiber cloth layer is fixedly arranged on the upper surface of the core layer; the second high-alkali-resistant glass fiber cloth layer is fixedly arranged on the lower surface of the core layer; a plurality of cavities are formed inside the core layer; the cavities are filled with light-weight plastic foam bodies. The sandwich plate provided by the invention is formed by gluing three plate elements with different performances and different thicknesses. The surface layer is the high-alkali-resistant glass fiber cloth mainly used for bearing tension and bending moment; the core layer is a grid structure type core layer made of regenerable bamboo plywood rich in resources; the grid structure type core layer is filled with the plastic foaming bodies and is mainly used for bearing shearing force. The composite plate has the characteristics of light weight, floating performance, splicing performance and high durability; the modular design is realized; the production cost is reduced.

Description

technical field [0001] The invention particularly relates to a composite sandwich board and a floating body for a floating body structure, and belongs to the technical field of machinery. Background technique [0002] The floating structure is a floating marine structure that is independent of the land and is composed of several modules to form a large-scale floating structure to meet political, military and economic purposes. It is not affected by water depth and has a flexible arrangement. It forms a composite structure system together with mooring devices and marine protection facilities such as breakwaters. It is one of the necessary conditions for the development, utilization and protection of marine resources in my country. Ordinary composite sandwich panels are usually laminated with metal material panels and composite material core panels. They have the advantages of high strength and high toughness. They have been widely used in ship structures, but they have poor c...
