What does a kernmantle rope consist of?

A kernmantle rope consists of two distinct parts: a core and an outer sheath. The core is typically made of strong fibers that provide the rope with its tensile strength, while the outer sheath serves several important functions, including protecting the core from abrasion, UV damage, and environmental conditions, as well as enhancing the overall durability and handling characteristics of the rope. This design is crucial for the performance and safety of the rope in various applications, including climbing and rope access work.

The other options do not accurately reflect the structure of a kernmantle rope. A single continuous fiber does not offer the required strength for climbing or heavy load applications, while a rope that consists only of a sheath component would lack the necessary support from a core. Additionally, a multi-strand rope without a core would not meet the specific design criteria and advantages provided by the kernmantle construction, which is essential for safety in high-stakes scenarios like rope access work.
