Abstract
Reduction of extensional stiffness in helical cords during bending fatigue was investigated carrying out some experiments, FEM analysis and mechanical analysis. The cords were constructed of stranded glass filaments and Resorcinol-Formalin Latex, and were used in synchronous belts. The stranded glass filaments were de-bonded and the extensional stiffness was reduced after the bending-fatigue. The FEM results showed that the reduction of extensional stiffness could be explained by the initiation and extension of the de-bonding in the cord. A simplified mechanical model was proposed to explain the reduction of extensional stiffness of cords.
