Abstract

Composite is made from two or more constituent materials with significantly different physical or chemical properties that, when combined, produce a material with characteristics different from the individual components. The mechanical property of a composite depends mainly on the physical and chemical properties of not only the resin, reinforcement used but also the hardener and solvent used. This paper highlights the experimental investigation on the effect of Acetone and Ethyl Alcohol solvent on composite laminates of teak wood powder and fly ash reinforcement with epoxy. The function of the solvent is to reduce the viscosity of the matrix to ensure the uniform distribution of the particulate reinforcement in the matrix upon stirring. Against this background, the present research work has been undertaken to explore the effect of acetone and ethyl alcohol solvent on wood powder and fly ash reinforced with epoxy. Hardener is added to the resin reinforcement mixture to ensure faster and uniform curing of the composite laminate at room temperature. But the hardener used (hy 951) being hydrophilic, absorbs moisture on exposure to atmosphere. The absorbed moisture adversely affects the curing of epoxy resin. This effect is more pronounced when the composite contains wood particles which also hydrophilic and absorbs moisture. Thus the present research also explores the effect of moisture on the curing properties of the composite. The present work thus aims to compare the effect of the ethanol and acetone solvent as well as the hardener properties on the flexibility of wood-flyash epoxy resin fiber reinforced polymer composites using SEM, XRD, FT-IR test results. © 2017 Elsevier Ltd.
