Carbon fiber composite high-pressure hydrogen storage tank and manufacturing process thereof

Abstract

The invention discloses a carbon fiber composite high-pressure hydrogen storage tank and manufacturing process thereof. The carbon fiber composite high-pressure hydrogen storage tank comprises a tank body, a gas guide opening is formed in one side of the tank body, a reinforcing part used for improving the strength of the tank body is arranged in an inner cavity of the tank body, the side end of the reinforcing part is fixedly connected with the inner wall of the tank body, and the tank body and the reinforcing part are both made of carbon fiber composite materials. According to the carbon fiber composite high-pressure hydrogen storage tank and a manufacturing process thereof, a manufacturing process of the carbon fiber composite high-pressure hydrogen storage tank is further disclosed. The inner cavity of the tank body of a hydrogen storage tank provided by the the carbon fiber composite high-pressure hydrogen storage tank is provided with the reinforcing part for connecting and supporting the two ends of the inner wall of the tank body, and the inner wall of the tank body is provided with a reinforcing ring along the circumferential direction, so that the overall strength and rigidity of the hydrogen storage tank are improved, and the hydrogen storage tank is safe and reliable under high pressure.

Description

technical field [0001] The invention relates to the technical field of hydrogen energy, in particular to a carbon fiber composite material high-pressure hydrogen storage tank and a manufacturing process thereof. Background technique [0002] The storage of hydrogen is one of the key links in the application of hydrogen energy. In order to store hydrogen efficiently and stably, it is necessary to store more hydrogen in the same storage space, that is, to store hydrogen at a high density, and to ensure stability and security. [0003] The existing types of hydrogen storage tanks are mainly divided into pure steel metal cylinders (Type I), fiber-wound cylinders with steel liners (Type II), fiber-wound cylinders with aluminum liners (Type III) and fiber-wound cylinders with plastic liners (Type III). Type IV) 4 types. Type I and Type II bottles have low hydrogen storage density and poor safety performance, making it difficult to meet the requirements of vehicle hydrogen storag...

AI Technical Summary

Problems solved by technology

However, Type IV bottles still have many problems such as how to seal the plastic liner and the metal bottle mouth, and whether the plastic liner can still meet the use requirements during the entire life cycle of the gas cylinder.
