abstract The results of examinations of polyamide 6 with quartz sand and glass fiber composites are presented. A composite was made using an extrusion machine collaborating with a granulator. The samples for the examinations were made using a Krauss Maffei KM65-160C1 screw injection moulding machine. Samples from polyamide 6 were also made to compare the properties of the composites and unfilled polymer. Investigations of the mechanical properties: tensile strength and hardness were carried out, and also the structure was determined by means of scanning electron microscopy. The aim of the investigations is to determine the influence of the filler on the composite properties and to receive a new, cheaper constructional material. The properties of the composite were determined from samples produced by injection moulding. As a result of such a method of sample preparation, the properties were conditioned by the processing parameters. The investigations were performed in order to estimate the processing capability and usability of PA6 composites with quartz sand and glass fiber addition. The lowest value of tensile strength of the polyamide 6/quartz sand composite was obtained. An increase in the hardness value of PA6 filled with quartz sand and glass fiber was obtained. The character of the changes of tensile strength and hardness values for the examined materials was evaluated, which proves the essential influence of the filler addition on the mechanical properties change. The tensile strength of the composite increases, while the hardness increases as the content of quartz sand and glass fiber increases.
