The article presents an analysis of the influence of the qualitative and quantitative composition of composites on their electrical conductivity and mechanical properties. Composites of this type are the subject of research on the possibility of shielding the electromagnetic field. For this purpose, samples of composites based on recycled metal materials were prepared. Metal flakes were mixed in fixed amounts by weight with PVC powder. Various types of reinforcing fibers were added to the mix. Short fibers were obtained by grinding textile and cellulose materials. The samples thus prepared were formed under pressure. The following tests were made on such samples: hardness, elongation and deflection forces, impact tests, electrical conductivity. The analysis of mechanical data and the results of resistance measurements enables the development of a model describing the relationship between these parameters and the quantitative composition and kind of reinforcement of the presented composites.
