Polymer composites containing waste dust from power production II. Strength characteristics of composites based on UPR/HIPS polymer system

Milena Koleva, Venceslav Vassilev, Gergo Vassilev


Polymer composite material based on “unsaturated polyester resin/high impact polystyrene” polymer system as matrix and waste dust from power production as filler was studied. The waste was mechanically activated at dry conditions at room temperature for 30 minutes. Strength characteristics – impact, bending and compressive strength – dependance on the waste concentration was determined. The optimal results were achieved at waste concentration of 10 w.%. Morphology observations of filled systems were performed to clarify the influence of the structure on composite’s properties.
