dc.description.abstractThis study investigates the transition from static to kinetic friction for structural polymers and continues previous research conducted by Dr. N. S. Eiss, B. McCann, and R. Molique. A new test apparatus which simultaneously measures friction, normal load, and relative velocity was developed to study this transition. The polymers used in this study were nylon, ABS, polycarbonate, and fiberglass filled and unfilled polypropylene. Creep effects of polymers on the static coefficient and thus the drop in friction was investigated. Friction tests were conducted to determine the effect of normal load, surface roughness, and material composition on the transition from static to kinetic friction. A double value friction-velocity relationship was found whenever a drop in friction occurred. The material composition seems have a larger effect on friction induced vibrations than surface roughness. A few conclusions about why certain static to kinetic transitions occur are made.en
