Background. High operating properties and economic attractiveness encourage the wide use of polymeric composite materials (PCM) for products of various applications.Competitive manufacturability of PCM sliding bearings (SB) production motivates tribological investigations of the materials. Patterns of friction coefficients changing with speed and loading intensity in a friction area of PCM SB is the subjectof our research. The goal of the work is to estimate the possibility of increasing friction and wear characteristics of the heavily loaded sliding bearings made ofPCM under the conditions of defect-free manufacture.
Materials and methods. The analysis of causes of manufacturing defects in slidingbearings production is given for the stages in technological process of PCM stripwinding. The importance of theoretical and experimentalstudies of physical and mechanical properties of products made of PCM at the stages of productionand operation at extreme conditions is substantiated.
Results. The results of modeling the behavior of «shaft-sleeve» tribological conjunction under different operational loading conditions in the presence of dry friction are shown. Critical values of pressure and speed are established. Exceeding criticalvalues will lead to friction surfaces gripping.
Conclusions. A further increase of lubricating properties of sliding bearings made of PCM is possible through treating SB with oil at the final operation of manufacturing.
