Abstract

A carbon fiber composite propeller for a ship comprises a metal hub and four carbon fiber composite blades installed on the metal hub. The metal hub and the carbon fiber composite blades are assembledthrough installation clamping grooves and installation protrusions, and adhesive layers are additionally arranged so that the metal hub and the carbon fiber composite blades are fixedly connected; each carbon fiber composite blade is formed by compositing a prefabricated body and a resin matrix, wherein the prefabricated body is formed by stacking and pasting joint-laying fabrics layer by layer on a mold of the prefabricated body. The prepared carbon fiber composite propeller has the advantages of being high in size precision, high in strength, good in rigidity, light in dead weight, low in noise, resistant to corrosion, resistant to microbial adhesion and the like, and meanwhile has good fatigue performance and impact resistance.

Description

technical field [0001] The invention relates to the technical field of marine propellers, in particular to a carbon fiber composite propeller for ships and a preparation method thereof, in particular to a marine propeller made of carbon fiber composite materials. Background technique [0002] At present, with the development and growth of the shipbuilding industry, the science and technology involved are of great significance to safeguarding the national maritime rights and interests, accelerating marine development, and ensuring the safety of strategic transportation. [0003] Propellers (especially large marine propellers) are one of the core components of a ship's power system, and their manufacturing quality directly affects the performance and propulsion efficiency of the entire ship. With the in-depth research and exploration of scholars at home and abroad, the design and manufacturing technology of marine propellers has made significant progress. The manufacture of l...
