Integral forming method of easy-to-demold composite material storage tank

Abstract

The invention discloses an integral forming method of an easy-to-demold composite material storage tank, and relates to the technical field of composite material forming. The integral forming method comprises the following steps: preparing a sealed airbag which is made of a high-temperature and high-pressure resistant material according to the size of a to-be-formed composite material storage tank; sealing the sealed airbag after fully filling the sealed airbag with a compressed gas, and using the sealed airbag which is fully filled with the compressed gas as a mold of the composite material storage tank; coating the surface of the sealed airbag with a demolding agent or paving and adhering demolding cloth; completing fiber pavement of the composite material storage tank by adopting a filament winding method; solidifying the composite material storage tank on which filament pavement is completed by adopting an autoclave-vacuum bag method; carrying out gas bleeding and decompression on the sealed airbag, enabling the composite material storage tank to be separated from the sealed airbag, completing a demolding process, and obtaining an integral composite material storage tank. The integral forming method of the easy-to-demold composite material storage tank, disclosed by the invention, has the advantages that the technology is simple, the integral performance of the composite material storage tank can be increased, demolding is convenient, and the cost can be obviously reduced.

Description

technical field [0001] The invention belongs to the technical field of composite material forming, and in particular relates to an integral forming method of a composite material storage tank which is easy to demould. Background technique [0002] At present, in the production of composite material storage tanks at home and abroad, especially FRP storage tanks, the method of making the inner liner first and then winding the entire storage tank on the inner liner is generally adopted. When making the inner liner, the head and the cylinder are made separately first. Butting together, the lining is prone to a series of problems such as stress concentration, which affects the overall performance of the storage tank, and the process is complicated, which greatly increases the production time. Contents of the invention [0003] In order to solve the above problems, the present invention provides an integral molding method of a composite material storage tank that is easy to demo...
