MECHANICAL AND TRIBOLOGICAL PROPERTIES OF POLYMERS AND POLYMER-BASED COMPOSITES

Abstract

A definition of rigidity of polymers and poly-mer-based composites (PBCs) by an equation is formu-lated. We also discuss tribological properties of polymers and PBCs including frictions (static, sliding and rolling) and wear. We discuss connections between viscoelastic recovery in scratch resistance testing with brittleness B, as well as Charpy and Izod impact strengths relations with B. Flexibility Y is related to a dynamic friction. A thermo-physical property, namely linear thermal expansivity, is also related to the brittleness B. A discussion of equipment needed to measure a variety of properties is included.
