High strength steel wire rope core and method of making same

Abstract

The application provides a high-strength steel wire rope core, which comprises a center wire, a secondary outer layer wire and an outer layer wire. The center wire is a steel wire bundle, the steel wire bundle is composed of 6-18 thin steel wire bundles; the secondary outer layer wire spirally wraps the center wire, the secondary outer layer wire comprises 4-12 first modified sisal wires; the outer layer wire spirally wraps the secondary outer layer wire, the outer layer wire comprises a first combined wire and a second modified sisal wire, the second modified sisal wire is arranged in the gap between adjacent first combined wires; the first combined wire comprises a second steel wire and a plurality of ultra-high molecular weight polyethylene wires, and the ultra-high molecular weight polyethylene wire spirally wraps the second steel wire. Wherein, the first modified sisal wire and the second modified sisal wire are both graphene oxide-polyethyleneimine modified sisal wires. The multi-layer composite structure is adopted, so that the strength of the steel wire rope core is improved as a whole, and the steel wire rope core has high tensile resistance and supporting property.
