Fabrication and Characterization of PPS /40%GF/nanoCaCo3 Hybrid Composites
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 4
Abstract
In the present work fabrication of composite material(PPS+40%GF+NANO CaCO3) was carried out and their tensile properties viz tensile strength, tensile strain(%),young's modulus, energy at maximum load and brinell hardness number were found and surface morphology of tensile fracture was analyzed by using SEM and EDS. Specimens of Polyphenylene sulfide (PPS)/Glass Fiber(GF) hybrid composites are prepared with four different compositions of nanocalcium carbonate(CaCO3), viz., 0,3,5 and 7%.Each specimen consisting of 40%GF.The specimens are fabricated by using micro-compounder with micro injection molding machine. Tests are conducted on these specimens to determine the tensile strength, tensile strain, young's modulus energy at maximum load and hardness number at room temperature using universal testing machine and Brinell hardness testing machine. The influence of the nano-CaCO3 content on the mechanical properties tensile of hybrid composites was studied. Surface morphology of tensile fracture of the hybrid composites is analyzed by using Scanning electron Microscope (SEM).Point chemical analysis of the hybrid composites is analyzed by Energy Dispersive Spectrum (EDS).Thus it gives the various inorganic elements present at a particular location. It is found that the reinforcing and toughening effects of the PPS/GF hybrid composites are increased by adding nano-CaCO3.The tensile strength, tensile strain, young’s modulus and energy at max load of these composites increased nonlinearly with theaddition of the nano-CaCO3.
