Study of performance of polyamide with fly ash addition with different contents of filler was carried out. In this article studies were performed: dynamical mechanical properties, thermal properties and structure research. The profiles of changes in the value of storage modulus E' and tangent of mechanical loss angle tg delta depend on the temperature and frequency of vibrations. The crystallinity degree was examined using DSC methodology whereas the structure was analysed by means of the optical microscope. The increase in the value of storage modulus versus temperature and vibration frequency for the samples with addition of filler and the increase in the crystallinity degree and polymer matrix with reduced addition of fly ash were observed. A reduction in size of the structural components was also found, particularly for the composites with filler content.
