Polymer matrix composites (PMCs) are light weight and have high strength to weight ratio, owing to which they are attractive for aviation and automotive industries. Amongst PMCs, glass fiberepoxy composites are being widely used. Replacement of synthetic materials by naturally available materials (i.e. agricultural products) as fiber and/or resin in making composites will ensure bio-degradability and eco-friendliness. In the view of developing natural fiber reinforced composites, in this work sisal fibers treated with/without cardanol oil have been investigated for their water absorption and strength characteristics. The investigation revealed that when compared to the untreated fibers, the cardanol treated fibers exhibit (i) 35 % reduction in water absorption and (ii) increased tensile strength property.
