Sažetak
In this paper, hybrid composites were prepared with polyester matrix reinforced with fiberglass and jarosite industrial waste particles as filler. Jarosite waste released from zink metal extraction process is very hazardous in nature due to the presence of toxic substances such as zinc, lead, cadmium, copper and other metallic and non-metallic oxides. The disposal of jarosite released from Trepca Zink Industry in Kosovo has become a major environmental concern. This work presents the attempt of immobilizing the jarosite waste as a value added product into the hybrid composites. Therefore, the hybrid composites were prepared with polyester matrix reinforced with five sheets fiberglass chopped strand mat and adding 5, 10 and 15 wt. % of jarosite waste particles as filler. Hand lay-up technique was adopted for preparation of the composite with previous ultrasonic probe dispersion jarosite particles in polyester resin. Morphology of prepared composites was analysed by optical microscope. Water absorption of the composites was determined by immersing specimens in distilled water at 25 ° C and 50 °C for different time durations. Flexural properties (flexural strength, modulus and apparent interlaminar shear strength), Charpy impact strength and hardness were determined and analyzed. The highest values of flexural strength, modulus, apparent interlaminar shear strength and Charpy impact strength were achieved for hybride composites with addition of 10 wt. % of jarosite waste particles as filler in polyester matrix reinforced with five sheets fiberglass. The highest hardness was measured for the sample containing 5 wt. % of jarosite filler in the fiberglass reinforced polyester matrix.
