Modification of polymer materials by various kinds of fillers is presently applied very often in massive
production. This is due to the need for materials with better properties and lower prices for parts. One of the
newest solutions is the filling of polymers with fly ash. This results in a change in products properties and
reduction the amount of waste in the form of ashes. This article shows the results of investigations of
thermomechanical properties of polyamide 6 modified by fly ash from the combustion of biomass.
Comparative analysis of unfilled polyamide and polyamide composites with the addition of 5%, 10% and 15% of
fly ash was performed. The specimens were obtained using injection moulding technology. The commercial
name for the Polyamide 6 used in this study is TARNAMID T-27 and was manufactured by Zakłady Azotowe
Tarnów. Fly ash manufactured by GDF Suez Energia Polska S.A. was applied as a filler. The investigations of
mechanical properties were made using a harness by pressing ball method, impact strength by Charpy method
and tensile strength. Differential scanning calorimetry (DSC), softening temperature by Vicat, and colour
investigations were also performed. Pictures of microstructure were made.
