The study of mechanical behaviour of Al2O3 filler: epoxy composites

This work constitutes of the Tensile strength and compression strength of 2% ,4% and 6% of Aluminum oxide filler addition with 20%(constant) Chopped E-glass fiber(3mm in length) reinforcement epoxy composite materials .An attempt has been made to develop 2%,4% and 6% of Aluminum oxide filler addition with 20%(constant) Chopped E-glass fiber(3mm in length) reinforcement epoxy composite materials with low density and economical, according to ASTM D638 Type IV Standard and ASTM D ¿ 1621. using resin -LY556 as a matrix material and hardener -HY 951 with 20% Chopped E-glass fibre(3mm in length) as the reinforcement material with different % of aluminum filler addition using hand layup fabrication technique. It is found that appreciable improvements in Tensile strength,Hardness number compression strength properties of 6% of Aluminum oxide filler addition with 20%(constant) Chopped E-glass fiber(3mm in length) fibers reinforced epoxy composites when compared with 4% and 2% Aluminum oxide filler addition.
