In kernmantle ropes, which component primarily provides abrasion resistance?

• A. Core
• B. Mantle
• C. Both equally
• D. Neither

Answer: (C)

In kernmantle ropes, the outer sheath is the part that takes the abuse from rubbing against rocks, hardware, and other rough surfaces. Its braided or woven structure is specifically designed to resist abrasion and wear, protecting the inner core. The core inside is made of long fibers that primarily provide strength and energy absorption, not abrasion resistance. So the component that primarily provides abrasion resistance is the mantle—the outer sheath—while the core handles load-bearing properties. If the mantle wears through, the core is exposed and the rope’s overall durability is compromised, which is why relying on the core for abrasion resistance isn’t appropriate.
