Problems solved by technology

[0003] However, many problems in the existing carbon fiber composite core wire manufacturing technology restrict its popularization and application.
In addition to the high production cost and complicated process, carbon fiber has high modulus, high hardness, low elongation at break, and its composite material is hard and brittle, resulting in low flexibility of carbon fiber composite mandrel, and the winding coil is easy to crack or break
In addition, carbon fiber has a certain conductivity, which is a defect for it as the main component material of the reinforced mandrel of high-voltage overhead cables, and the insulation of carbon fiber composite mandrel should be improved as much as

Abstract

The invention discloses a three-layer concentric high-performance fiber composite material cable core rod and a manufacturing method thereof. The internal layer of the core rod is made of carbon fiber composite material, the intermediate layer is made of glass fiber composite material, and the external layer is made of aramid fiber composite material so that a concentric structure is formed by the three layers. The invention also discloses a manufacturing method of the core rod. Carbon fiber, glass fiber and aramid fiber are infiltrated in liquid resin in an open glue tank; carbon fiber composite material preformed core rod is firstly formed by the impregnated carbon fiber; the impregnated glass fiber evenly wraps the carbon fiber composite material preformed core rod so that a two-layer concentric structured carbon fiber/glass fiber composite material preformed core rod is formed; and aramid fiber through impregnation and online ultrasound processing evenly wraps the carbon fiber/glass fiber composite material preformed core rod so that a three-layer concentric structured carbon fiber/glass fiber/aramid fiber composite material core rod is obtained, and thus the core rod is enabled to possess the characteristics of high strength, high toughness, high insulation, low density and high tensile modulus.

Description

technical field [0001] The invention relates to the field of aerial cables, in particular to a three-layer concentric high-performance fiber composite cable mandrel and a manufacturing method. Background technique [0002] Conductors with carbon fiber reinforced resin-based composite materials as reinforced mandrels (referred to as carbon fiber composite core conductors) have been more and more used in overhead high-voltage power distribution system lines since they were successfully developed by CTC Company in the United States in 2003. Compared with the traditional steel core, the carbon fiber reinforced resin matrix composite core has the characteristics of higher tensile strength, lower density, corrosion resistance and no rust. Therefore, the carbon fiber composite core wire can use soft aluminum as the carrier fluid, which has higher conductivity, thereby reducing the resistance loss of the wire. At the same time, the composite core is almost non-conductive, and there ...
