Abstract

The invention discloses a carbon fiber elbow used for ships, which includes an elbow body and threaded sleeves arranged in two ports of the elbow body, the threaded sleeves are made of polytetrafluoroethylene, and the elbow body is cured by a resin matrix production. When used, this kind of carbon fiber elbow for ships has significant advantages such as high strength, good rigidity, light weight, corrosion resistance and anti-microbial adhesion, smooth inner surface and no scaling, and has good fatigue performance and impact resistance. .

Description

technical field [0001] The invention relates to the technical field of marine fittings, in particular to a carbon fiber elbow used for ships and a manufacturing method thereof, in particular to a carbon fiber composite material elbow provided with a polytetrafluoroethylene threaded sleeve. Background technique [0002] Seawater piping is an important part of electromechanical equipment such as ship power systems and auxiliary systems. Corrosion of ship piping has always plagued ships, and it is one of the most prominent causes of ship failures, seriously affecting the safety of ships. Corrosion in seawater is unavoidable. The ship's seawater piping system is responsible for important tasks such as fire protection, ballasting, cooling, and flushing. According to different functions, the seawater piping system is divided into systems with different functions and distributed in various parts of the ship. Most seawater piping systems are in humid, high temperature In the harsh ...
