Deck belts are made from synthetic materials or special fibers. Depending on the applications of these belts, the properties of the synthetic material varies accordingly. It’s not surprising to see riding mower belts with poor build quality stretching and losing their shapes.
However, aromatic polyamide (ARAMID) belts crack into little pieces of fiber when they are old. These types of deck belts are brittle and their fibers have high resistance to heat. Unlike standard belts with carbon fiber materials, ARAMID belts have higher tensile strength.
