Submarine pressure shell and preparation method thereof

Abstract

The invention discloses a submarine pressure shell which comprises a steel skeleton and a shell body, wherein the steel skeleton is fixed on the inner surface of the shell body; the shell body is formed by compounding a lining layer, a reinforcing layer and an outer protection layer sequentially from inside to outside; the reinforcing layer is formed by winding a bamboo skin sheet with adhered amino resin for multiple layers; and the lining layer and the outer protection layer are both formed by compounding bamboo fiber nonwoven fabric and epoxy vinyl ester resin. The invention also discloses a preparation method of the submarine pressure shell. The preparation method comprises the following steps: pretreatment of the bamboo skin sheet, resin preparation, thickness design, preparation of midship-stern shell body, preparation of a midship-bow shell body, connection of the steel skeleton and connection of the midship-stern shell body and the midship-bow shell body, wherein the steps are all carried out in a condition that the ambient humidity is lower than 40% RH. The submarine pressure shell prepared in the invention is green and environmentally friendly, light in weight and low in cost, and increases the travel speed and endurance mileage while the deformation resistance is strong and the damping property is good.

Description

technical field [0001] The invention belongs to the technical field of underwater ships, and more specifically relates to a pressure-resistant shell of a submarine. In addition, the invention also relates to a preparation method of the submarine pressure shell. Background technique [0002] Submarine is one of the important ships in naval operations. It can move flexibly underwater and is used to attack warships on the opponent's surface and submarines in the water. It can also attack important military targets on land. It can also undertake mine-laying when necessary. , Reconnaissance and transportation of soldiers and important military supplies. Submarines have good concealment and surprise attack capabilities, and can continue to sail for a long time and long distances in the water. There are three types of submarine structures: single hull, double hull, and single-double mixed hull. The single hull is a pressure-resistant hull, and the double-hull is a non-pressure-re...

AI Technical Summary

Problems solved by technology

[0003] At present, submarine hulls are generally made of high-strength steel such as HY-80 and HY-100, but the manufacturing process of steel consumes a lot of energy and emits a large amount of harmful gases, causing serious air pollution

Moreover, the steel itself has a large mass, which limits its driving speed
