Embodiment Construction

[0020] The invention is described in further detail below with reference to the accompanying drawings. This fiber layer weaving technology including the intermediate layer weaving technology is clear to those in the field.

[0021] figure 1 The three-layer schematic diagram of the basic structure of the fiber woven layer is given, figure 2 The process flow chart is given, see figure 2 , Fix the mold 22 on the mold support 21, heat up the outer mold 27, prepare the braiding machine 23, the braiding machine 25, the fiber spindles and the intermediate layer 24, figure 1 The fiber layer is wrapped on the core mold 22 and dipped through the dipping tank 26, together with the intermediate fiber, enters the outer mold 27 under the traction machine 28, heated and solidified, and the product comes out from the right end to 6 meters in length or design requirements After the length of the cutting machine 29 automatically cuts, it becomes the product. In the weaving process, two or more ...

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 field of construction water supply and drainage, sewage discharge, optical fiber, cable, highway and railway underground construction, water conservancy irrigation, chemical industry, and mining fluid transportation pipeline technology, specifically a fiber woven pultruded pipeline and a production method. [Background technique] [0002] With the development of China’s economy, the safety requirements for municipal engineering, building water supply and drainage, power system, chemical industry, communications, water conservancy and irrigation are also increasing. Therefore, it is more important to choose a better pipeline. For a long time, the pipeline uses metal. Made of materials, such as steel pipes, iron pipes, etc., traditional metal pipelines are easily rusty due to their high energy consumption during the production process, multiple procedures, and metal conductivity in harsh environments such as humidity, di...
