The ductility and stiffness properties of the coconut coir with reinforced epoxy resin were carried out. Specimen containing fibre lengths of 5mm, 10mm and 15mm were moulded and treated with alkali (NAOH) and also not treating the fibre with alkali. The samples were prepared in accordance with ASTM standard D3039. An Instron machine was used to do the tensile tests of the samples. The tensile test machine has an electro-mechanical sensor used for purpose of controlling the strain in the test pieces. The results show that the deflection of the composite coir is associated with the ductility of the material. the ductility of the composite is significantly influence by the increasing length of the fibre content. The material deflection ratio is more in the treated fibre compared with the untreated fibre. This is however not well pronounced in the 5 mm fibre content. The study provides the understanding the relationship between the deflection of the material and the load applied during application for purpose of deducing the ductility properties of such material.
