Abstract. Plastic are non-metallic material characterized by an amorphous structure and manufactured by melting together several constituents, such as resins, plasticizers, dyes, fillers, etc. These materials can be deformed with relative ease at temperatures of 140-180 ° C. In turn, composite materials are constituted by a metallic or non-metallic mass reinforced with resistance elements in the form of long fibers, short and very short fibers, granules, fabrics, felt, etc. The use of parts made of composite materials in conditions characterized by the action of abrasive wear processes requires the knowledge of additional information regarding the behavior of these materials under such stresses. Samples of cylindrical form were made from two polymeric composite materials, namely Granite and PolyMide using a 3D printing process. For abrasive erosion testing, a pin-on-cylindrical surface pattern was chosen. As such, an abrasive testing device adaptable to a universal lathe was designed and achieved. The nature of the composite polymer material, the granulation of the abrasive paper, and the pressing force of the test sample on the abrasive cylinder were taken into account as input factors in the process. The output parameter monitored was the loss of material from the test sample as a result of the abrasion process. The experimental results were processed using specialized software. There were determined empirical mathematical models capable of highlighting the direction of action and the intensity of the influence exerted by some input factors in the testing process on the loss of material by the test sample as a result of the abrasion process. It was found that, for the conditions in which the experimental research was carried out, the strongest influence was exerted by the nature of the composite polymer material, followed by the magnitude of the pressing force of the test sample and by the granulation of the abrasive material.
