Description
Summary:The natural fibres are lightweight, economic and easily biodegradable and are eco-friendly due to which a study is performed to prepare a green composite whose both constituents’ fibre and matrix are derived from nature. The reinforcement used for this study is Hemp and Sisal which are derived from the leaves of the Hemp and Sisal plant. The composites of these materials have high specific strength and good mechanical properties. The matrix used is Novolac also called Cardanol Phenol-Formaldehyde derived from Cashew nutshell. Composite laminates were prepared using the materials and were tested for their water absorption properties and tensile properties. From the study, it was found that the sisal fibre reinforced with Novolac resin has better water absorption properties than Hemp. Also the tensile strength of the Hemp laminate was greater than the Sisal laminate and Hemp-Sisal laminate. The Hemp-Sisal laminate showed intermediate properties between Hemp laminate and Sisal laminate.
