The reinforcement cords in the belts are made of hundreds or thousands of tiny fibers, and the rubber adheres to the outermost layer but doesn't penetrate the entire cord. I think a bad clamp design could result in the same sort of failure where the rubber slides over the cords and stretches.Mark Rehorst DMDhttps://www.blogger.com/profile/13616282129430791353noreply@blogger.comtag:blogger.com,1999:blog-5001794558945659136.post-38317206496483077862019-01-02T00:05:25.112-06:002019-01-02T00:05:25.112-06:00Would be interested in comparison with proper (Gat...Would be interested in comparison with proper (Gates) Kevlar belts. As I recall, Kevlar has highest stiffness (and perhaps better adhesion to the rubber?).<br /><br />Also wonder if the results you see are more about the quality of fabrication, rather than the material in question. Kind of suspect even fiberglass reinforced belts should be more than adequate. Preston L. Bannisterhttps://www.blogger.com/profile/03201415630192091526noreply@blogger.com
