What percentage of the load is typically carried by the core of Kernmantle rope?

The core of Kernmantle rope is designed to bear the majority of the load when the rope is in use. Typically, it accounts for 70% to 90% of the rope's overall strength. This characteristic is essential for ensuring the rope can endure dynamic and static loads during rescue operations, climbing, and other applications where safety is paramount.

The outer mantle serves primarily as a protective cover for the core, contributing to the rope's durability against abrasions and environmental factors, but it does not significantly contribute to the load-bearing capacity. Understanding the functional roles of the core and the mantle helps users to select the appropriate type of rope for specific applications and to assess the safety margins related to load-bearing with more accuracy.
