Embodiment 1

[0041] A braided composite material reinforcing cord, comprising yarn 1 and core 2.

[0042] see figure 1 , the yarn surrounds the core, and is woven around and wraps the core in an interwoven manner to form a yarn wrapping layer.

[0043] In this embodiment, the circumference of the core 2 has two layers of yarn covering layers, and the rotation directions of the yarns 1 of the two layers of yarn covering layers are opposite to the winding direction of the core 2, so that the rotational torque is offset. see figure 2 , from the inside to the outside are the adjacent first yarn covering layer 11 and the second yarn covering layer 12, the ends of the two yarn covering layers are flush, figure 2 In order to clearly illustrate the two overlapping layers, the ends of the yarn groups of the two layers of yarn covering layers are cut off in turn to show a ladder shape.

[0044] see figure 1 , the yarn covering layer includes eight strands of yarns 1 evenly distributed on the p...

Embodiment 2

[0049] The difference from the first embodiment is that in this embodiment, the yarn covering layer is only one layer, please refer to image 3 .

Embodiment 3

[0051] A carbon fiber spoke adopts the braided composite material reinforcing cable proposed in the first embodiment, wherein the core 2 is a carbon fiber rod, and the tensile performance of the carbon fiber rod is improved by weaving yarn 1 around the carbon fiber rod. In this embodiment, the carbon fiber rods are flat spokes, and the rotation directions of the yarns 1 of the two adjacent yarn coating layers are opposite, so that the rotational torsion force is offset, and the parallelism of the planes on both sides of the flat spoke is ensured from the shape.

[0052] In other embodiments, the core 2 may also be of other composite materials to make composite spokes, such as glass fiber spokes.

[0053] Experiment 1: The tensile failure comparison experiment was carried out on the large-angle woven flat spokes obtained in this example and the metal spoke products of the same specifications of other brands on the market, and the tensile failure comparison experiment table 1 was...

Abstract

The invention provides a woven composite material reinforcing cable, a composite material spoke and a manufacturing method of the composite material spoke. The reinforcing cable comprises a core and yarn. The yarn surrounds the core and surrounds and wraps the core in a staggered weaving mode to be woven into a yarn wrapping layer, and at least one yarn wrapping layer is arranged. The yarn is woven around the core in a staggered weaving mode, the yarn covers the core to form the yarn wrapping layer, the yarn formed by mutual winding is tightly attached to the periphery of the core and cannot be loosened, and when one yarn is broken, the yarn wrapping layer cannot be loosened and can be continuously used for a long time, so that the reliability of a product is improved, and the service life of the product is prolonged.

Description

technical field [0001] The invention relates to a braided composite material reinforcing cable, a composite material spoke and a manufacturing method thereof. Background technique [0002] In the historical process of human development, the use of ropes has provided various conveniences for human life, which has a history of nearly 5,000 years. Historically, ropes have long been dominated by natural fibers, and man-made fiber rope products have only been used for about seventy years. [0003] Carbon fiber and other multi-fiber hybrid braided composite material reinforcement cables are designed to meet the special needs of cable products in various industries. Various fiber tows are mixed and woven into long strips of 3D braided yarn bundles according to a certain proportion, and then the base material is completed by pultrusion molding process. The resin is infiltrated and cured at high temperature. This kind of reinforcing cable products can be widely used in various indu...
