Influence of SiC Filler on Mechanical Properties of Glass Fabric Reinforced Polyester Composites
Keywords:
Glass-Polyester Composite, SiC filler, Wet hand lay up technique, Mechanical properties, Morphology of fractured surfacesAbstract
In this study, E-glass fabric reinforced polyester composite filled with two levels (2.5 and 5 wt %) of SiC particles were prepared by wet hand lay up technique. The mechanical properties were evaluated by tensile, flexure and hardness tests. Mechanical tests showed that the tensile and flexure strength of glass fabric reinforced polyester increase with increase of SiC filler. The glass fabric reinforced polyester filled with 5 wt. % SiC exhibited drastic improvement in the mechanical properties. Hardness of the SiC filled composites also increased from 94 to 107, which is highest for 5 wt. % SiC. The morphology of fractured surface features was described using scanning electron microscopy (SEM). The failure modes of the tested specimens were evaluated and showed good agreement with the literature.
