IMPROVEMET SOME MECHANICAL PROPERTIES OF EPOXY MATRIX COMPOSITE

Abstract

commercially available epoxy resin is taken as material in this study for improvement his mechanical properties to manufacturing of some parts of airplanes, by using micro ceramic particles like AL2O3 and SiO2 as fillers material in epoxy resin to produce particulate reinforced polymer composites.The composites are fabricated by using hand lay-up technique in different volume fractions of AL2O3 such as ( 0% ,5% ,10% ,15% ) and 10% volume fraction of SIO2 and ( AL2O3 + SIO2 ) for choose best among themto use it in manufacturing .It was observed that used ( 10% AL2O3 ) reinforced epoxy composite is exhibited maximum value of hardness and impact strength while the use of ( 10% SIO2 ) reinforced epoxy having better values of flexural strength . At last The volume friction and the kind of fillers plays an important role in the enhancement of mechanical properties like impact strength , flexural strength and hardness
