Abstract. A brief overview of construction polymer-composite materials with an indication of their main properties is presented. It is noted that these materials are advisable to use in the manufacture of products of complex shapes, in particular gears with a complex configuration of gear rings. Results of experiments with structural polymer materials to study their characteristics of friction and tensile strength, carried out using the universal friction machine MTU-1 and SHIMAZU AGS-500X machine, are presented. Samples of polymer parts are made using FDM technology. Presented graphs showing dependence of the friction coefficient and ultimate tensile strength on the filling factor of polymer samples, are to be taken into account in the design and manufacture of parts.

Keywords: construction polymer materials, coefficient of friction, tensile strength
