Viscoplastic properties and the friction coefficient of preplasticized composites have been studied at rubbing against a forming surface as a function of filling degree, particIe size, temperature of the melt and lubricant of the forming surface. The composites under study are based on a secondary polypropylene and wood sawdust of various fractions. The pressing force and thickness of the fiat disc-like components were found to be interrelated with the viscoplastic properties of the compositions and conditions at the interface with the forming surface.
