Abstract

Presently composites are being made using either both the binder and the reinforcing fibers are synthetic or either one of the material is natural or synthetic. In this study we had prepared bio-degradable composite by using natural fiber i.e. banana fiber and pant based resin i.e. dried mass of euphorbia latex. Length of the fiber and its orientation play an important role in the mechanical properties of the fiber reinforced polymer composites. For better understanding of the effect of fiber length on the physicomechanical property of the composite in this study we had prepared euphorbia latex banana fiber composite with varying fiber length and charactrised for water absorption, impact strength, flexural strength and flexural modulus. Results shows that with increasing fiber length of the composite from 1mm to 6mm, water absorption increases and impact strength of the composite increases from 20 to 30% and 37 to 43 J/m respectively whereas flexural strength and flexural modulus of the composite increases from 9.5 MPa to 12.9 MPa and 980 MPa to 1290 Mpa respectively with increase in fiber length from 1mm to 4mm further increase in fiber length result in decrease of flexural strength. Effect of surface modification on physico-mechanical properties of the campsite also studied. Result shows that hemicellulose and lignin presents on the fiber surface removed on treatment sodium hydroxide which results increase in surface roughness and improvement in mechanical properties.
