Summary:【Objective】The umbilical cable is one of the core pieces of equipment for marine scientific exploration. It typically uses high-strength steel wires as the load-bearing elements. However, steel wires have a high density, and as the operating water depth increases, the proportion of the umbilical cable's own weight in the safe working load also increases, reducing the safety margin for ultra-deep water applications. Therefore, there is a need for lightweight design of umbilical cables.【Methods】The light-weight umbilical cable replaces steel wires entirely with low-density, high-hardness aramid Fiber Reinforced Polymer Compsite Materials (FRP) in its innermost layer. In the middle layer, steel wires are partially replaced at intervals, while the outermost layer maintains a full steel wire structure to enhance overall wear resistance and facilitate heat dissipation through the gaps in the loadbearing layer when seawater seeps in. To mitigate interlayer wear, a wear-resistant layer is extruded on the surface of t
