Problems solved by technology

[0002] The carbon fiber composite core cable is a cable designed to replace the steel-cored aluminum stranded wire cable. This cable has the advantages of low density, high tensile strength, small sag, and large current-carrying capacity. In the case of catastrophic fracture, the main reason is that this kind of composite core is sensitive to surface defects, which will cause surface damage during production, winding and installation. This is its biggest shortcoming. In order to make full use of the designability of composite materials and improve To enhance the reliability of the core with wires, a single carbon fiber composite core can be designed to be wound by many small carbon fiber core rods, that is, a composite rope core. This kind of rope core can make the force more uniform and greatly improve the performance of the cable. safety performance, but there is still a lack of this composite rope core and its molding process and manufacturing equipment

Abstract

The invention discloses a hybrid fiber composite rope core. The hybrid fiber composite rope core is formed by twisting a carbon fiber composite core strand and six hybrid fiber composite core strands. Each composite core strand is formed by compounding thermosetting resin, curing agents, accelerants, release agents and packing through a thermosetting resin system. The invention further discloses a hybrid fiber composite rope core forming process. The process includes the steps of preheating, etching, impregnating, single-strand preforming, single-strand outer-layer composite core coating, twisting forming, deep curing, winding and the like in sequence. The invention further discloses a rope core manufacturing device. The rope core manufacturing device is composed of a fiber yarn creel, a fiber preheating / etching device, a resin impregnating tank, a single-strand preforming mould, an outer-layer composite core strand coating mould, a forming device, a curing device and a winding device in sequence. Through the hybrid fiber composite rope core, the hybrid fiber composite rope core forming process and the rope core manufacturing device, a rope core can be formed in one shot, the probability of mould blocking in the process of pultrusion production is reduced, the production efficiency is improved, and the production cost is lowered.
