BROWSE_DETAIL_TAB_ABSTRACT

The improvement of physical properties of polycarbonate is still great interest of scientists due to the huge application areas. In this study polycarbonate matrix was reinforced with glass fiber (GF), mica (MC) and in hybrid form. The preparation of composites was carried out using co-rotating twin screw micro-compounder at 280 oC and the test samples were prepared by laboratory scale injection-molding device.The percent compositions of added fillers for PC/GF and PC/MC composites were 5%, 10%, 20%, and 30%. The total percentage of both filler was kept as 30% for hybrid composites (MC%/GF%) of which comspositions were 5/25, 10/20, 20/10, 25/5, respectively. The characterizations of obtained composites were examined via tensile test, impact test, melt flow index test, differential scanning calorimetry analysis and scanning electron microscopy methods. The obtained results showed that the best values of tensile strength were obtained for the lowest mica concentration and 20% glass fiber containing composites gave the optimum value. The concentration increment of the additives more than these values caused agglomerations and reduction of homogeneousvdistribution of them in the PC matrix, which were revealed by scanning electron microscopy.
