Abstract

The invention relates to a glass fiber reinforced plastic finned tube and a production method. The glass fiber reinforced plastic finned tube is characterized by comprising a first long fiber weaving layer, a third long fiber weaving layer and a middle layer between the first long fiber weaving layer and the third long fiber weaving layer, wherein the middle layer is formed by longitudinal fiber layers. The tube is cylindrical, the outer wall of the tube is provided with spiral corrugated fins, and the inner wall of the tube is a smooth surface. The production method comprises the following steps of: a weaving process, a gumming process, a finning process, a curing process, drawing and cutting into finished products. Compared with the prior art, the invention has the advantages that the advantages of lightness and high strength of a fiber composite material are utilized, the weaknesses of insufficient annular strength and rigidity of a general pultrusion tube are overcome, the defects that longitudinal strength of a winding tube is insufficient, more workers are needed, and the process is fussy are solved, the continuous production is realized, and the production efficiency is high.

Description

[technical field] [0001] The present invention relates to a fiberglass reinforced pipe related to continuous drawing and weaving, and relates to the technical fields of drainage, sewage, optical fiber, cable, underground construction of roads and railways, water conservancy irrigation, chemical industry, and mine fluid transportation pipelines, including new materials, specifically Said to be a kind of FRP reinforced pipe and production method. [Background technique] [0002] With the development of my country's economy, the safety requirements for municipal engineering, power system, chemical industry, communication, and water conservancy irrigation are also increasing. Therefore, it is more important to choose a better pipeline. For a long time, the pipeline is made of metal materials. Such as steel pipes, iron pipes, etc., due to the high energy consumption and many processes in the production process of traditional metal pipes, as well as the metal conductivity, easy to r...
