Continuous fiber reinforced pipe and continuous fiber reinforced pipe connection structure

Abstract

The invention relates to the field of composite high-pressure pipelines, and aims to provide a continuous fiber reinforcement pipe convenient to connect and good in end reinforcement effect and a continuous fiber reinforcement pipe connecting structure. The continuous fiber reinforcement pipe comprises a main pipe, a spigot connected with one end of the main pipe and a bell connected with the other end of the main pipe, wherein the main pipe comprises a main outer layer, a main reinforcement layer and a main inner layer, the spigot comprises a spigot outer layer, a spigot reinforcement layer and a spigot inner layer, and the bell comprises a bell outer layer, a bell reinforcement layer and a bell inner layer; the main outer layer, the main inner layer, the spigot outer layer, the spigot inner layer, the bell outer layer and the bell inner layer are formed by solidifying thermoplastic plastics, and the main reinforcement layer, the spigot reinforcement layer and the bell reinforcement layer are formed by winding continuous fiber impregnated belts. The continuous fiber reinforcement pipe and the continuous fiber reinforcement pipe connecting structure are convenient to connect, axial force will not damage the pipeline connecting position, and the end reinforcement effect and the anti-internal-pressure capacity of the continuous fiber reinforcement pipe are good.

Description

technical field [0001] The invention relates to the field of composite high-pressure pipelines, in particular to a continuous fiber reinforced pipe and a connection structure of the continuous fiber reinforced pipe. Background technique [0002] The invention of Chinese patent application number: 201310023074.2 discloses a continuous fiber reinforced thermoplastic composite high-pressure pipe with an inner wall and an outer wall, and an intermediate layer is arranged between the inner wall and the outer wall; the inner wall and the outer wall are respectively made of thermoplastic resin materials; A continuous fiber resin reinforced layer formed by thermoplastic compounding of fiber resin layers; each fiber resin layer is made of a strip material pre-impregnated with continuous fiber or continuous fiber bundles and thermoplastic resin materials; the fibers in each fiber resin layer are glass fiber, aramid fiber, or carbon fiber. The traditional continuous fiber-reinforced t...
