Investigation of Methods for Improving the Frictional Properties of Rubber Compounds Used in Footwear

Efforts to improve frictional qualities entailed the testing of various tread designs, additive materials such as cork and cotton flock, composite specimens, and channeled and siped specimens. Tests were conducted at room temperature and in some cases at O F. The data obtained show changes in tread...

Description
Summary:Efforts to improve frictional qualities entailed the testing of various tread designs, additive materials such as cork and cotton flock, composite specimens, and channeled and siped specimens. Tests were conducted at room temperature and in some cases at O F. The data obtained show changes in tread design, composites and coarse additive materials are ineffective in improving friction on smooth surfaces. Siping of flat specimens showed slight improvement of friction on wet surfaces. Compounds that resist hardening at O F show better retention of friction at that temperature. The order of skid resistance of several compounds changes when tested on a different surface.
