Embodiment

[0036] Raw material specifications:

[0037] Carbon fiber: Torayca T700SC-12K, tensile strength 4900MPa, tensile modulus 235GPa, strain 2.1%, monofilament diameter 7μ;

[0038] Epoxy resin system: 25°C viscosity 1200-2000cP, 25°C density 1.2g / cm 3 ;

[0039] Glass fiber felt: MFS-50;

[0040] Fiberglass stitched felt: GF / 960-50-35.

[0041] figure 1 is a schematic diagram of the production equipment used to produce the composite core of the present invention. Such as figure 1 As shown, the carbon fiber is unwound from the creel 1 with a tension adjustment device at a constant tension, passes through the yarn guide plate 2 in sequence, and passes through the preheating box 3 in parallel, removes moisture in the preheating box, and heats and softens A sizing agent on the surface of carbon fiber to improve the effect of resin infiltration. Then pass through the yarn guide plate 2 ' and enter the glue groove 4. After fully infiltrating, enter the preforming mold 5. At thi...

Abstract

The invention relates to a carbon fiber-resin composite core for overhead cables, which consists of a carbon fiber-resin composite core layer and a protective layer wound on the core layer, wherein the protective layer is a fibrofelt and / or fiber fabric-reinforced resin material layer. Compared with the prior art, the carbon fiber-resin composite core for the overhead cables has the advantages of reducing the unit length weight of a product and improving flattening resistance.

Description

technical field [0001] The invention relates to a fiber-reinforced composite material, more particularly to a core material of an aerial cable. Background technique [0002] In the past ten years, with the development of overhead cable technology, the original steel core has been replaced by a higher strength non-metallic fiber composite core. The composite core reinforced cable (ACCC) significantly reduces the weight and weight of the cable compared with the steel core cable. degree of sagging. Known non-metallic reinforcing fibers for overhead cables include carbon fiber, Kevlar, basalt, glass fiber, aromatic polyamide, liquid crystal fiber, high-performance polyethylene, etc. Among them, carbon fibers have been increasingly used in overhead cable cores due to their high tensile strength and low thermal expansion coefficient. [0003] Chinese patent ZL03809284.0 discloses a composite material core for cables, the composite material core includes an inner core and an oute...
