Fiber-woven pultrusion pipeline and production method

Abstract

The invention relates to a fiber-woven pultrusion pipeline and a production method, wherein shape of a pipe is like a cylinder; an inner wall and an outer wall of the pipe are smooth surfaces; inside diameter of the pipe is 20-400 mm; size and thickness of the pipe are determined according to a design requirement; the pipe is woven by a plurality of long fibers to form fiber layers; each fiber layer is provided with a layer of resin materials, and is formed by heat curing; and the fiber layers are composed of a plurality of fiber-woven layers. The production method comprises the following steps: weaving by a plurality of layers; dipping with glue in vacuum; solidifying; dragging; and cutting finished products. Compared with the prior art, the advantage that fiber composites have light weight and high strength is played, the defect that transverse strength and rigidity of normal pultrusion pipes are poor is overcome, and the problem that longitudinal strength of fixed length winding pipes is poor, labor force is more, and processes are fussy also are solved in the invention. Large-size fiber-woven pipelines are pulled and extruded under a state that moulds do not move at the first time; the pipelines can be produced continuously; and production efficiency is high.

Description

[technical field]

[0001] The invention relates to the technical fields of building water supply and drainage, sewage, optical fiber, cable, underground construction of roads and railways, water conservancy irrigation, chemical industry, and mine fluid delivery pipelines, specifically a fiber braided pultruded pipeline and a production method. [Background technique]

[0002] With the development of our country's economy, the safety requirements for municipal engineering, building water supply and drainage, power system, chemical industry, communication, and irrigation are also increasing. Therefore, it is more important to choose a better pipeline. 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, and the metal conductivity and easy to rust in harsh environments such as humidity, dirt, and coastal salt spray in actual use , Short life, high facility maintenance costs an...
