Abstract

Synthetic fibers (such as glass, carbon, ceramic fibers, etc) which were imported at huge cost could be replaced by natural fibers such as flax, hemp, jute, kenaf, etc. which are widely used. In this research work, banana fiber reinforced vinylester matrix composites have been developed by hand lay up molding technique with varying parameters, such as fiber condition (untreated and chemically treated), fiber sizes 10,30 and 50 cm and fiber content (10%, 30% and 50% by weight). The developed banana fiber reinforced composites were then characterized by chemical methods. The results show that tensile strength increases with increase in the fiber size and content; however, after a certain size and  fiber content, the tensile strength decreased again. The maximum Tensile strength was 1127N/mm2 at a fiber length of 2.2cm and volume fraction of 36%. The maximum flexural strength was 67.15N/mm2 occurring at km fibre length and 50% vol fraction. The   minimum creep strength was 2x10-4s-1 occurring at 3.2cm fibre length and 30% vol fraction.
