Preparation method of composite material thruster stator

Abstract

The invention discloses a preparation method of a composite material thruster stator. The thruster stator is divided into three parts including a propeller hub, paddles and a guide pipe, the roots of the paddles are connected with the propeller hub, tip parts of the paddles are connected with the guide pipe, and the overall thruster stator is made of composite materials. All paddles of the stator achieves paving in a stator paddle die in a prepreg and fiber cloth doping manner, transition fibers in certain sizes are led out at the roots and the tip parts of the paddles from the doped fiber cloth and are used for being subject to connection with the propeller hub and the guide pipe and co-curing molding subsequently, continuity of the fibers in the paddles and the guide pipes is guaranteed, and the molded stator is excellent in overall mechanical property. The composite material thruster stator prepared through the preparation method is small in weight, good in strength, high in reliability, reasonable in structure and simple and practical in molding method.

Description

technical field [0001] The invention relates to a preparation method of a propeller stator, in particular to a preparation method of a composite material propeller stator. Background technique [0002] Since the propeller is subject to large thrust and torque, the strength and rigidity of its manufacturing materials are required to be high. Generally, propellers of ship propellers are made of nickel-aluminum-copper alloy materials. Compared with other metal materials, propellers made of nickel-aluminum-copper alloy materials have the advantages of corrosion resistance, easy processing, and the ability to prevent marine organisms from attaching, but they also have many problems, such as high processing costs, easy fatigue, cracks, cavitation, etc. Severe denudation, relatively poor acoustic damping, etc. In order to solve these problems, researchers have carried out extensive and in-depth research. On the one hand, they optimize the performance of the propeller by improving...
