Glass fiber reinforced polyester (G-P) composites are synthesised with an addition of Silicon carbide (SiC) particles by varying weight percentage (0, 2.5, and 5 %) using hand layup technique followed by compression moulding. The prepared specimens were cut according to ASTM standard to determine hardness, and impact strength. The fabricated specimens were characterized by dynamic mechanical analysis (DMA) technique. Density, hardness, and impact strength was found increases with increase in the filler loading. 5 wt% of SiC in to G-P [5 G-P] composites improved the impact strength by 16.27 % compared to that of unfilled G-P composites. More over the dynamic mechanical thermal analysis was carried out to study the Visco elastic behavior of unfilled and SiC filled G-P nanocomposites with varying temperature and frequency. © 2015 Elsevier B.V., All rights reserved.
