Abstract
Currently, there is an expanding demand of composite materials for various engineering applications. Glass fiber reinforced polymer composites, prepared by injection molding, is among these composites. Injection molding method has basic process parameters which determine the mechanical behaviors of polymer matrix composites (PMCs). However, only few studies have been reported on the effects of injection molding process parameters for a typical short glass fiber reinforced polypropylene composites. In this study, process parameters such as melting temperature, mold temperature, packing pressure and flow rate were used for fabrication of the specimens. The modeled specimens, loaded by a compression force, were simulated and analyzed using moldflow (R2018) and ansys (R19.2) software. The specimens were also subjected to experimental studies of compression testing to study the effects of process parameters on mechanical properties of the composites. As a result, it is found that fiber orientation, deflection and mechanical properties of the composites are significantly affected by the injection molding process parameters. So, in pursuit of increasing the mechanical properties of the composite, set of injection molding process parameters of 80°C mold temperature, 240 °C melt temperature, 60 cm3/s flow rate and 40 MPa packing pressure are required. From the numerical and experimental studies, variations of melt temperatures significantly influence the mechanical properties of the short glass fiber reinforced polypropylene composite parts molded by injection molding.
