Embodiment Construction

[0031] Embodiments of the present invention provide a composite material sandwich structure and a manufacturing method thereof, which can simultaneously meet the requirements of corrosion resistance, light weight, easy molding and impact resistance of the hull.

[0032] The technical solution in the embodiment of the present invention is to solve the above-mentioned problems, and the general idea is as follows:

[0033] A multi-layer structure composed of a surface layer, a first shielding layer, a first structural layer, a sandwich layer, a second structural layer and a second shielding layer is provided. If the surface layer and the first shielding layer are waterproof and anti-corrosion materials, the waterproof and corrosion resistance of the sandwich structure can be improved; if the first and second structural layers are mixed with ultra-high molecular weight polyethylene fibers with lighter weight And carbon fiber, and can be laid on any curved surface, it can have exce...

Abstract

The invention discloses a composite sandwich structure and a making method thereof. By setting a multi-layer structure consisting of a surface layer, a first shielding layer, a first structural layer,a sandwich layer, a second structural layer and a second shielding layer, the composite sandwich structure can adapt ship housing manufacturing, and also can meet the requirements of corrosion resistance, light weight, easy shaping and impact resistance for ship housings at the same time.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a composite material sandwich structure and a manufacturing method thereof. Background technique [0002] Small ship hulls are usually made of steel, aluminum alloy, or composite materials, among which fiberglass composite materials are widely used in small ships due to their excellent corrosion resistance, light weight and easy molding. In recent years, unmanned control technology has begun to involve the field of ships. At present, unmanned ships are mainly used for hydrographic surveys, safety and environment monitoring, customs anti-smuggling, and troop patrols; The needs of monitoring ships are more and more extensive. Since the unmanned ship needs to move alone for a long time, it has high requirements for cruising range, ship maintenance and impact resistance. The traditional metal hull structure cannot meet its weight requirements. At the same time, the comp...
