Coefficient of friction of dry slash pine and southern red oak on three tension-grip facings

Informally Refereed

Abstract

A urethane material proved to have nine times higher static friction coefficient (0.9) than smooth steel (0.1) on radial and tangential wood surfaces pulled parallel to the grain. It is probably superior to 22O-grit garnet paper or sand coatings for tension-grip facings in lumber testing machines.
