The work demonstrates selected results of the investigations on surface properties and wear resistance of polypropylene based wood-polymer composites (WPC) reinforced with wood flour. WPC are broadly applied in construction and automotive sectors, where mechanical, thermal as well as moisture absorbing characteristics are of great importance. In order to get information about wear resistance of such composites Taber wear test is applied. Surface properties are investigated before and after tribological test. Contact angle values of the investigated compositions are compared after different wear periods (0, 2000, 5000 and 10000 cycles) with abrasives H22 and CS17.
