Mechanical and Acoustic properties of Bagasse – Coconut Coir based Hybrid Reinforced Composites

ABSTRACT

In this paper, a hybrid composite is developed from natural fibers of bagasse and coconut coir. The mechanical and acoustic properties of the hybrid composites are investigated. While preparing the hybrid composites, the polyester resin is used as a matrix. Treated and untreated specimens were prepared by varying the weight percentage of bagasse and coconut coir fibers and resin. Various mechanical tests including tensile test, hardness test, flexural test, impact test and impedance tests were carried out as per ASTM standards. Experimental results on comparison reveal that the developed hybrid composite has a better sound absorption coefficient values and mechanical properties. Hence, the proposed hybrid composite could be used in Industries.
