Utilization of waste dolomite dust in carbon fiber reinforced vinylester composites

The present study was designed to explore the applicability of dolomite dust (a waste from a quarry) as filler in polymer composites. Therefore, fixed carbon fiber reinforced vinyl ester composites with varying proportions (0, 5, 10 and 15 wt.%) are manufactured subsequently evaluated for physicomechanical sliding wear properties. Experimental results indicate that density, void content, impact energy, hardness, tensile modulus, flexural modulus increase content increase. On other hand, continuous decrease strength observed increased content. tests were performed using L16 orthogonal design, considering four parameters: dust, distance, applied load, velocity according Taguchi method. It found most noteworthy parameter rate, followed by load distance.
