The paper investigates selected operating characteristics of polymer composites used in friction pairs. Eight poly-mer composites were investigated: PE with MoS2, PTFE with graphite, PPS with glass fibre, PA6-G with mineral oil, POM with aluminium, PTFE with MoS2, PTFE with bronze and PEEK with glass fibre. Results of hardness, compressive strength and porosity of the analysed composite materials are presented. The paper also presents test results of the friction force, friction coefficient, temperature near the friction node, and linear wear. The results are plotted in diagrams and discussed in the context of friction and wear assessment of the tested materials. On increasing the external load, all analyzed operating parameters of the friction process increase too. Among the tested polymer composites, the best results were obtained for PA6-G with mineral oil. PTFE-matrix composites –despite their good results of the friction coefficient – are less desired than POM with aluminium because their use is less cost-effective.
