Experimental analysis of mechanical properties and FTIR analysis of areca fiber-reinforced epoxy composites incorporating Al2O3

The interest in natural fiber reinforced polymer composites is rapidly growing in terms of both industrial and domestic applications. The present study is an attempt to improve the mechanical properties of composites made of areca fiber and epoxy resin with the incorporation of alumina filler. The filler was added in various percentages (0wt%, 2wt%, 4wt%, 6wt%, 8wt %) and the composite fabrication was done by compression molding technique. The fabricated composites were tested for tensile, hardness and impact properties. The results demonstrate that 8wt%Al2O3-A-E composite shows superior (tensile, impact, Hardness) mechanical composites. For improvement of hardness and strength main contributing factors were uniform dispersion of Al2O3 (Aluminum oxide) particles and better load transfer between Al2O3 (Aluminum oxide) particles and epoxy matrix. The effect of alkaline treatment of areca of fibers was verified by FTIR analysis. The experimental investigation attempt to improve the Areca epoxy composites by loading fillers and for the applications of light weight and high strength components in different sectors like aerospace and automobiles. Fracture surfaces were analyzed using Scanning Electron micrograph (SEM).
