INFLUENCE OF THE AMOUNT OF FILLER DERIVED FROM INDUSTRIAL WASTE ON THE MECHANICAL PROPERTIES OF POLYMER COMPOSITE MATERIALS

This article analyzes the effect of the amount of tar product obtained from industrial pyrolysis on the mechanical properties of ED-20 epoxy-based polymer composite materials. The tensile strength, microhardness, and impact toughness of fiberglass compositions containing 5, 10, and 15 parts by mass of the tar product were compared. For the cold-cured samples, the tensile strength was 51.4, 52.1, and 49.1 MPa, the microhardness was 22.3, 22.9, and 20.8 MPa, and the impact toughness was 20.4, 19.2, and 18.2 kJ/m2, respectively. The highest values for tensile strength and microhardness were observed in the composition with 10 parts by mass, while the composition with 5 parts by mass exhibited the highest impact toughness. When the tar product content was increased to 15 parts by mass, all three mechanical indicators decreased. The results indicate the need to collectively consider the mechanical requirements placed on the composite when selecting the amount of filler. The highest table values of tensile strength and microhardness were observed in the 10 mass fractional composition, while the 5 mass fractional composition prevailed in impact viscosity. All three mechanical indicators decreased when the tar product was increased to 15 mass fractions.
