Tensile properties of coir and fleece fibers reinforced poly-lactic acid hybrid green composites

Abstract

Hybrid green composite is a combination of several layers of fiber types or laminate that are arranged with a certain number and sequence. This type is used to replace the deficiencies of both types of fibers and can combine the advantages. In this paper, tensile properties of hybrid green composite biodegradable from natural fibers (coir and fleece) and Poly-Lactic Acid (PLA)matrix were investigated. The synthesis of composite material was carried out with five samples i.e coir, fleece, 5/15% mass of coir and fleece, 10/10% mass of coir and fleece and 15/5% mass of coir and fleece reinforced PLA biodegradable matrix were synthesized using hot press molding at temperature of 170°C pressure of 10MPa and time molding of 10 minutes. Characterization of tensile strength and modulus of elasticity of the material using the Tensile Test Machine ASTM D 638. The result show that the tensile properties (tensile strength and modulus of elasticity) of the sample affected by addition of fiber fraction. The result confirmed with the result of morphology test by SEM (Scanning Electron Microscope).
