Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that the axial fiber of the hollow hollow pipe of composite material formed by unidirectional pultrusion is easy to crack and the torsional strength is not high, and the application range is limited. A multi-layer cable-stayed winding production method for composite hollow pipes that can resist bending and torsion, and a set of corresponding production equipment was invented at the same time

Embodiment 1

[0028] As shown in Figure 1 and 2.

[0029] A kind of multi-layer pultrusion winding production method of composite empty composite profile, it comprises the following steps:

[0030] Firstly, the multi-strand composite material fiber (such as carbon fiber, glass fiber, etc.) is drawn out from the axial constant tension wire rack 1 by a tractor at a uniform speed, and the multi-strand tow is impregnated along the mandrel through the axial dipping tank 2. 7 (can be a circular, elliptical or polygonal structure) arranged in parallel in the axial direction to form an uncured first layer of axial composite material layer consistent with the shape of the mandrel 7;

[0031] Make the above-mentioned first layer of axial composite material tow that is consistent with the shape of mandrel 7 pass through the axial dipping tank, and impregnate the adhesive (can be determined according to the type of composite material tow used, which can be epoxy Resin and (vinyl resin) are driven forw...

Embodiment 2

[0037] As shown in Figure 1 and 2.

[0038]A multi-layer pultrusion and winding production line for empty composite profiles of composite materials, which includes an axial tension wire rack 1, an axial dipping tank 2, a mold heating device 4, a tractor 5 and a cutting machine 6, and the axial constant tension The wire rack 1, the axial dipping tank 2, the mold heating device 4, the post-curing box 10 tractor 5 and the cutting machine 6 are all installed on the frame, and the axial dipping tank 2 and the oblique dipping tank 12 are preferably equipped with Heating the dipping tank of the constant temperature device to ensure that the binder will not thicken, prolong the use time, and facilitate the fiber to have good pultrusion permeability. It is best to have a corresponding glue volume control mechanism at the exit of the dipping tank. Squeeze excess binder on the tow back into the dipping tank and control the glue content. Between the outlet end of the axial dipping tank 2...

Abstract

The invention relates to a production method and a production line of a composite hollow pipe with transverse winding fibers. Transverse winding layers winded on the surfaces of the fibers in opposite positive and negative directions are pulled and extruded in a longitudinal direction. Therefore, the invention enhances the bending resistant capability of the composite hollow pipe, eliminates a lamination phenomenon caused by using a single longitudinal composite hollow pipe, largely enhances the performance of the composite hollow pipe, and widens the application field of the composite hollow pipe.

Description

[0001] Part of the content of the invention has also applied for a utility model patent technical field [0002] The invention relates to a production method and production equipment of a composite material fasting pipe (such as carbon fiber, glass fiber, etc.), especially a production method and a production line of a composite material fasting pipe, specifically a composite material fasting pipe Multi-layer cable-stayed winding production method and production line thereof. Background technique [0003] As we all know, composite material pultrusion molding technology was born in the 1950s, and the process gradually moved towards standardization and normalization in the 1970s. It is an important method for manufacturing composite materials, with specific features: high specific strength, corrosion resistance, and dimensional stability. Pultruded composite profiles can replace metal and non-ferrous metal profiles, and are currently widely used in petrochemical building mate...
