Rope fibers are categorized into what two types?

• A. Synthetic and Natural
• B. Fibers: Natural and Metallic
• C. Organic and Inorganic
• D. Synthetic and Composite

Answer: (A)

Fibers used in rope fall into two broad groups: natural and synthetic. Natural fibers come from plant or animal sources such as Manila hemp, sisal, cotton, or wool. They were common historically and have characteristics like biodegradability and variability in strength, moisture sensitivity, and handling. Synthetic fibers are man-made from polymers—nylon, polyester, polypropylene, and similar materials—offering higher strength-to-weight ratios, greater abrasion resistance, more consistent quality, and better moisture performance. This natural-versus-synthetic split best captures the practical differences that affect how a rope behaves in the field, including strength, durability, maintenance, and safety factors. The other options introduce categories that don’t describe rope fibers in general use—for example, metallic fibers aren’t a standard rope-fiber category, organic/inorganic isn’t a typical division, and synthetic with composite would overlook natural fibers entirely.
