What are drive belts primarily made from?

Drive belts are primarily made from rubber composite materials with internal reinforcing fabric due to their need for flexibility, strength, and durability during operation. The rubber component provides the necessary grip and wear resistance, allowing the belt to transfer power effectively between moving parts of a vehicle or machinery. The internal reinforcing fabric, such as polyester or nylon, enhances the structural integrity of the belt, preventing it from stretching or breaking under tension and heavy loads.

This combination of materials allows drive belts to function efficiently in a variety of conditions, making them suitable for automotive applications as well as industrial machinery. Their ability to withstand the forces exerted in mechanical systems while providing reliable performance is critical. Other materials, like metal or plastics alone, do not offer the same level of flexibility and durability required for drive belts, while natural fibers like cotton and leather are not commonly used in modern belt manufacturing due to their reduced longevity and mechanical performance compared to synthetic composites.
