High-strength fiber pipeline and manufacturing method thereof

Abstract

The invention discloses a manufacturing method of a high-strength fiber pipeline. The manufacturing method comprises the following steps: S1, weaving inner layer yarns on the surface of a core mold toform an inner woven layer, wherein the thickness of the inner woven layer is 0.5-1.5 mm; S2, introducing warp yarns into the surface of the inner braided layer, wherein the warp yarns are uniformly and radially distributed on the surface of the inner braided layer; S3, spraying a layer of resin adhesive on the surface of the structure prepared in the step S2 to form a gel coat I; on the basis ofweaving the inner and outer fibers, the middle layer adopts a reinforcing layer in a unit form consisting of a warp yarn layer, a winding yarn layer and a wrapping cloth layer, the pipeline produced in the mode is attractive in inside and outside weaving appearance, wrapping cloth is additionally used for winding extrusion glue, on one hand, the glue is evenly distributed, on the other hand, the formed structural strength is high, the performance of the pultrusion pipeline is guaranteed, and finally the linear speed of the whole production line is not affected in the wrapping cloth mode.

Description

technical field [0001] The invention relates to a manufacturing method, in particular to a high-strength fiber pipe and a manufacturing method thereof. Background technique [0002] Compared with traditional steel pipes, ductile iron pipes, PE pipes and other traditional pipes, glass fiber pipes have great advantages in terms of tensile strength, environmental protection performance, good corrosion resistance, good impermeability, and frost resistance. more competitive in the market. In recent years, the application of glass fiber pipes has become more and more extensive, showing the huge application potential of glass fiber pipes, and the market prospect is very optimistic. [0003] However, most of the domestic manufacturers adopt backward production technology, and there are common disadvantages such as waste of materials, poor production environment, insufficient tensile strength, and low production efficiency. The radial fiber layer and the hoop fiber layer, the fiber...

Problems solved by technology

[0003] However, most of the domestic manufacturers adopt backward production technology, and there are common disadvantages such as waste of materials, poor production environment, insufficient tensile strength, and low production efficiency. The radial fiber layer and the hoop fiber layer, the fiber pultrusion pipe composed of this structure basically has the performance of compressive resistance, bending resistance and internal pressure resistance; however, when the performance index is tested, the inner and outer braids are loose after cutting 8mm shape, which makes it poor in tear resistance, low in impact resistance, and at the same time, the wall thickness requirement of 4mm cannot be met, which leads to a narrow range of use for this type of pipe. Glue is required to ensure the strength of the pipe, but the existing pipe production method is difficult to overcome this problem, resulting in a loose state when the multi-layer fiber structure is combined, making it difficult to produce high-strength pipes. At the same time, in order to match the existing pipe For the existing production process, the change is relatively large, and the improvement of the process leads to a large investment in equipment, it is difficult to achieve modularization, and the production cost of the enterprise is increased.
