What effect do fibers running parallel in the core of a kernmantel rope have?

The fibers running parallel in the core of a kernmantel rope are designed to primarily provide the rope with its strength and load-bearing capacity. This construction enables the rope to effectively handle static loads, making it ideal for applications that require low stretch under tension, such as in vertical rescues and rappelling. A static rope is typically characterized by its limited elongation, which enhances safety and control when performing operations where a high degree of stability and security is required.

In contrast, the mantle of the rope provides added protection and enhances durability, while the core, with its parallel fibers, ensures that the rope can withstand heavy loads without significant stretching. Therefore, the specific arrangement of fibers in the core is essential in achieving the static characteristics of the rope, making it suitable for rescue operations.
