One of the more common complaints of automobile owners is noise (squeaks and clicks) caused by plastic coponents in the passenger compartment rubbing on each other. One possible cause of these noises is the release of energy stored in deflected plastic components when the friction drops as sliding commences. In this paper static and kinetic friction data are shown for ABS-ABS, Polycarbonate (PC)-PC, ABS-PC blends, and Styrene/Maleic Anhydride Copolymer (SMAC)-SMAC combinations. The effects of normal load, component elasticity, and polymer mechanical properties on the magnitude of static friction , the difference between static and kinetic friction, and friction instabilities such as stick slip are explored. The friction response of the polymers ranged from zero to multiple stick slip cycles, with noise must likely to be heard when multiple stick slip occurs. Low normal load and high component stiffness minimized the stick slip behavior. Glass fibers added to ABS-PC reduced the tendency to stick slip because the fibers increase the elastic modulus and reduce creep, both of which tend to reduce static friction.
