Thermal Degradation in Tire Cords

of any mechanical action. No attempt is made to answer the question concerning any possible mechanical degradation, such as has been observed under certain conditions by others [7, 10, 12], inasmuch as such mechanical degradation in road operation is inextricably bound up with the heat produced at the same time. The present investigation was designed to amplify and, if possible, explain the earlier work of Conrad, Lyons, and Tripp [3] which showed that cotton tire cords taken from tires that
