Fibrous reinforcement for air suspension and air suspension

Abstract

A fibrous reinforcement for an air suspension includes polyketone fibers. The fibrous reinforcement can improve the pressure resistance, the bending resistance, the peeling resistance between rubber/fiber, the fatigue resistance, and the durability of a rubber film of the air suspension. This reinforcement is formed from polyketone cords or composite fiber cords including polyketone fibers and other fibers. Since the polyketone fibers have excellent adhesion to the rubber and small elongation, the pressure resistance, the bending resistance, the peeling resistance between rubber/fiber, the fatigue resistance, and the durability of the rubber film of the air suspension can be improved by using the polyketone fibers as the fibrous reinforcement.
