Description
Technical Field
The utility model relates to a braided composite pipeline structure.
Background
With the gradual development of carbon fiber raw materials, the carbon fiber is applied to the existing plastic polymer pipeline production, so that the impact resistance of the pipeline is increased, and the process has become a brand-new development direction of the industry.
At present, the surface of the existing plastic polymer pipeline is directly woven and attached to the carbon fiber layer, but only one layer is often attached to the surface of the existing plastic polymer pipeline. Because friction force can be generated between layers when the layers are attached, the friction force can enable the carbon fiber material to generate angle bending and position moving conditions, and therefore the structural strength and the processing efficiency of subsequent products are affected.
But the multilayer structure can obviously replace the structural strength of the final product, especially the mode of combining the transverse direction and the longitudinal direction, so that the axial rigidity can be improved, and the reversing strength and the torsion resistance can be improved.
Therefore, how to solve the connection strength between the multi-layer carbon fiber materials and reduce the friction force in the processing process is one of the technical bottlenecks of the multi-layer composite pipeline reinforcement mode at the present stage.

The utility model aims to provide a woven composite pipeline structure, which solves the problems of low bonding strength and low structural strength of products in the prior art.
The woven composite pipeline structure comprises a pipeline layer of a base layer and a reinforcing layer covered on the surface of the pipeline layer, wherein the reinforcing layer comprises a parallel reinforcing layer positioned at the middle part and a woven reinforcing layer positioned at the outer part;

In order to ensure that a certain amount of epoxy resin is attached, the epoxy resin material on the surface of the carbon fiber material is attached by electrostatic adsorption or melt impregnation. Through the mode of adhering to epoxy, the frictional force condition in the follow-up multilayer winding process can be effectively reduced to better promote the structure reinforcing effect of multilayer reinforced structure.
Further, the powdered epoxy resin is filled between the braided reinforcing layer and the parallel reinforcing layer, and the powdered epoxy resin is melted and filled in the gaps after subsequent heating.
In order to ensure the reinforcing capability of the composite material, the number of the parallel reinforcing layers and the number of the woven reinforcing layers are at least one, and the theoretically best number of the parallel reinforcing layers is about 3, and the woven reinforcing layers are about one.
Further, the braided reinforcing layer is attached to the surface of the pipe layer by a rotary braiding apparatus, which may be either a conventional braiding apparatus or a winding apparatus with a rotary function.
The product can be applicable to the dimension specification that the outer diameter range of the pipeline layer is 2-100mm.
Furthermore, no staggered structure is generated among the carbon fibers in the parallel reinforcing layer, and the included angle between the carbon fibers in the parallel reinforcing layer and the central line of the pipeline layer is 0-5 degrees.
Further, the carbon fibers in the braided reinforcing layer are in a staggered relationship, and the carbon fibers are staggered, wherein the included angle between the carbon fibers and the central line of the pipeline layer is 30-55 degrees, and 210-235 degrees.
The beneficial effects are that:
in the structure, the outside is provided with a high-strength fiber reinforced braiding layer (the fiber in the direction of +/-45 degrees can be preferential), the middle is provided with a high-modulus fiber reinforced pultrusion layer (the fiber in the direction of 0 degrees can be preferential), and the structure can ensure that the composite material shaft tube has excellent axial rigidity, hoop strength and torsion resistance through the design of the constituent units. Wherein the parallel reinforcement layers provide axial stiffness and the woven reinforcement layers provide torsional resistance and hoop strength. According to the actual use requirement of the product, the number of layers, fiber orientation and thickness of the multi-layer structure can be further optimized and combined to prepare the high-rigidity and high-strength composite material shaft tube.
Meanwhile, the mode of adopting the epoxy resin as the intermediate connector can reduce the friction force of the carbon fiber layers in the winding process and can increase the connection strength between the carbon fiber layers as much as possible.
