Abstract

Abstract In the trending materials technology, nano composites are gaining importance due to enhanced mechanical, thermal and optical properties. Among various nanofillers used in fiber reinforced polymer nanocomposites, nanoclays have received several attractions among academia and researchers due to its high aspect ratio and characteristic exfoliation/intercalation properties. The stiffness of glass fibre reinforced polymer composites is not very high in comparison to carbon fibres. In the present work, an attempt has been made to enhance the stiffness and tribological properties of glass fibres by mixing nanoclays in the epoxy matrix. Hand lay up method was adopted to make ten layered glass fibre reinforced polymer hybrid composite. The weight percentage of nanoclay was 1%, 3%, 5%, and 7% to understand the behaviour of the hybrid composites. It was observed that 5% loading of nanoclay shows the optimum amount at which all the properties like hardness, impact strength, flexural strength and specific wear rate was increased. However, with further increase in nanoclays, all the above said properties were deteriorated. At 5% nanoclay content, hardness increased by 33.8%, impact strength by 74.8%, flexural strength and modulus by 37.5% and 37.67% respectively. Hence the above hybrid composite may be considered as a better composite for various structural and industrial applicationse.
