2.3 Polymer composite tribology In author’s knowledge, except for only ultra-high-molecular-weight polyethylene (UHMWPE) and probably nylons, no other polymer is currently being used in its pristine form for a tribological application. The reason is that no polymer can provide a reasonable low wear rate with optimum coefficient of friction required. Hence, there is a need to modify most polymers by a suitable filler that can reduce the wear rate and, at the same time, either increase or decrease the coefficient of friction depending on the design requirement. The filler can perform a variety of roles depending on the choice of the matrix and the filler materials. Some of these roles are strengthening of the matrix (high load-carrying capacity), improvement in the sub-surface crack arresting ability (better toughness), lubricating effect at the interface by decreased shear stress and the enhancement of the thermal conductivity of the polymer (Burris et al., 2008). The entire aspects of the tribology of polymer composites can be quite complex, and thus, a simple and efficient way to handle this topic is to classify the composites according to the role of the filler material in the composite, by modifying either the bulk or the interface (Briscoe, 1993). 2.3.1 Hard (strong) fillers in a softer matrix: Bulk modification PTFE, most well known self-lubricating polymer, is usually weak to external load, thus showing poor wear resistance. However, these kind of soft polymers with exceptional frictional property can be made also wear resistant by strengthening the bulk with hard or strong filler material such as particles of ceramics/metals or a suitable strong 15PDF Image | TRIBOLOGY OF POLYMERIC COATINGS FOR AGGRESSIVE BEARING APPLICATIONS
