Experimental Investigation of biobased hybrid composite Materials

Abstract

The aim of the present work is to find the best solution to the newlineselection of reinforcement materials substituted for the improvement of newlinethe composite material. The naturally available fibres like palm fibre, newlinehemp fibre and kenaf fibre were selected for the reinforcement in the newlineepoxy polymer composite. Surface treatment was carried out for the newlineimproved interaction between the polymer matrix and the fibre. It may newlinehighly improve the quality of surface of the fibre and improve the newlineadhesion quality between the fibre and the matrix. newlineThe observation in the test results showed difference in the newlineresult of the reinforced fibre at various volume percentages which was newlineprocessed with 4% sodium hydroxide and various volume percentage of newlineunprocessed fibre. The fabrication of composite laminate was done at newlinevarious volumes such as 20%, 30%, 40% and 50% of natural fibre newlinereinforcement. newlineThe best results of all the percentage were selected and newlineoptimum fibre reinforcement was selected from the results. Mechanical newlinecharacterisation of the composite was done after the specimen was newlinefabricated. As per the ASTM standards, the tensile properties, flexural newlineproperties, impact strength and hardness of the composite was found. newlineFrom the mechanical characterisations of the composite, newlineoptimum volume percentage was recorded. Further improvement was newlinevi newlinedone by adding of Egg Shell Particles (ESP) 800nm. At various newlinepercentages the mechanical characterisations was studied for the newlinecomposite that has ESP inclusions in it. The filler has improved the newlinematerial s thermal stability and the properties of wear for the composite, newlineeven though it has declined the tensile properties when there is addition newlineof ESP in the composite. newlineNew material was fabricated with optimum volume percentage newlineobtained from the observation of the mechanical characterisation newlineprocedure. Based on the inferences of the mechanical characterisation newlineand the predictions by regression algorithm which proved the newlineobservations true; the hybrid material was fabricated and tested for its newlineproperties.
