Abstract An attempt is made to formulate a framework within which the behavior of polymer composites under wearing conditions can be considered. Experimental results obtained with different types of polymer composite material [short fiber reinforced thermoplastics and continuous fiber (woven fabric) reinforced thermosets] worn under two extremely different conditions (sliding against smooth steel and severe abrasion by different abrasive papers) were used for this approach. The tendencies of wear rate vs. fiber volume fraction typical for the different composites and testing conditions are discussed along with the corresponding microscopic observations of the wear mechanisms. The wear data are correlated with the mechanical properties of the materials and with frictional as well as material factors having an effect on the individual wear mechanisms during the different wear processes. Information from the literature and the conclusions from this study are used to present a hypothetical model of a polymer composite microstructure, which is assumed to have both a high load-carrying capacity and a generally high wear resistance.
