Dynamic Analysis of Laminated Composite with Inclusion

Abstract

With growing environmental awareness, ecological concerns and new legislations, bio-fibre reinforced polymer composites have received increasing attention during the recent decades. This study focuses on the processing of seashell powder into micron size and utilizing the same as filler with glass fibres and epoxy resin in the preparation of the composite, thereby increasing mechanical strength. The constituents used in this composite showcase properties like higher strength, higher stiffness, chemical resistance, good insulation to electricity and lightweight. The components found in seashell such as Na, Ca, Al and C along with the S-glass fibre and the binding provided by the resin are responsible for enhancing hardness and tensile strength of the composite. Numerical analysis for the tensile test was done using ANSYS simulation for both composites with 5% filler (50% fibre + 45% resin+ 5% seashell) and without filler (50% fibre + 50% resin). Two laminate composites, with 5% filler (50% fibre + 45% resin+ 5% seashell) and without filler (50% fibre + 50% resin) were fabricated and their mechanical properties were compared using various tests like tensile and low velocity impact test with an impact velocity of 1 m/s, 2 m/s, 3 m/s and 4 m/s. The results from these tests were interpreted. The findings show that the specimen with 5% filler has more ultimate strength and impact strength when compared to the one without filler.
