To enhance the strength and durability of timing belts, manufacturers often incorporate reinforcement materials such as fiberglass or aramid fibers (e.g., Kevlar). These reinforcements prevent elongation and ensure that the belt maintains its shape under tension. Fiberglass is commonly used for its high tensile strength and ease of manufacturing, while aramid fibers are known for their impressive heat resistance and toughness. Using these materials in timing belts results in better performance under high-load conditions, reducing the likelihood of belt failure.

However, it is essential to note that environmental factors such as humidity and temperature can impact the longevity of leather belts. Maintaining a suitable operating environment is crucial to prevent issues such as cracking or drying out, which can lead to belt failure. Despite these challenges, the ability to repair or recondition leather belts adds to their appeal, as they can often be restored to full functionality rather than being discarded.
