The mechanical properties of a polycarbonate matrix composite with glass fiber reinforcements used for the manufacture of a multistage centrifugal pump impeller are researched in this article. The material properties are modelled using DIGIMAT (The Material Modelling Platform) to determine the strain resistance of the composite with different proportions of reinforcements. The Tsai–Hill failure criterion is used to determine the strength in all cases. The results have been verified by physical testing to determine the influence of the shape and mass proportion of reinforcements on its mechanical properties. The strength of the manufactured part is correlated to technological factors using the MARC MENTAT solver, and the most and the least favorable combinations of these factors are determined.
