Abstract

The invention discloses a carbon fiber composite propeller for ships, which includes a metal hub and four carbon fiber composite blades installed on the metal hub, and the metal hub and the carbon fiber composite blades are assembled through installation card slots and installation protrusions. An adhesive layer is added to make the two fixedly connected; the carbon fiber composite blade is composed of a preform and a resin matrix. The carbon fiber composite propeller prepared by the invention has the characteristics of high dimensional accuracy, high strength, good rigidity, light weight, low noise, corrosion resistance and anti-microbial adhesion, etc., and 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...
