The objective of the paper is to evaluate the mechanical behaviour of coconut coir reinforced with municipal solid waste. The mechanical properties like tensile strength, tensile modulus, flexural strength, impact strength, hardness and water absorption were studied .The study revealed the sample of fibres without size reduction showed higher tensile strength, flexural strength and impact strength when compared with different fibre length of 10mm, 20mm and 30mm respectively. The fibre board from MSW and coir have shown less moisture content and better flexural strength. © 2015, Sphinx Knowledge House. All rights reserved.
