ANALYSIS OF MECHANICAL PROPERTIES IN ZEA MAYS STRAW FIBER COMPOSITES

In recent year's Natural fiber reinforced composite (NFRC) are considered as a suitable alternative to engineering material due to their advantages like low cost, low density, high strength and stiffness to weight ratio, resistance to breakage during processing, low energy consumption, a lesser amount of pollutant emissions and biodegradable materials. They have excellent properties and are being extensively used in verity of engineering application like aircraft and aerospace etc. This paper examines the mechanical properties of Zea Mays Straw powder (ZMSp) particles reinforced polyester composites with the aim of producing a composite material showing enhanced properties for engineering applications. Zea mays straw particles were added in different volume fractions into polyester matrix at 5, 10 and 15 gram respectively. Composite samples were produced from these mixtures and the effect of the tensile properties of the composites was investigated. The tensile strength, tensile modulus values increases as the Zea mays straw powder. Among the three samples the 15gram added Zea mays composite bar gives better tensile modulus and strength than the other two samples.
