Natural fibre composite materials are one such capable material which replaces the conventional and synthetic materials for the practical applications where we require less weight and energy conservation. The present paper emphasizes the effect of Cloisite 30B on the newly identifiedCoccinia Indicafibre, which is extracted from a medicinal plant (i.e., Cucurbitaceae) by manual process. The chemically treatedCoccinia Indicafibre reinforced composite is prepared by using the epoxy resin and the detailed preparation methodology is presented. In this paper, the mechanical properties and morphological characterizations of nanoclay filled chemically treatedCoccinia Indicafibre reinforced epoxy composites were compared with the unfilled composite. The experimental evidence shows that the increase in weight percentage of nanoclay enhances the tensile, flexural, impact, compression properties of the treatedCoccinia Indicafibre reinforced epoxy composites. These results were also confirmed by the Scanning Electron Microscopy observations of composites and Fourier Transform Infrared Spectroscopy analysis of the chemical structure. Fibre pull-outs on the fractured specimen during physical testing of the composites were also investigated. As a results, the presence of 3wt.% nanoclay provides better interfacial adhesion between fibres and matrix, which gives the best results compare to others.
