Study the Effect of the Addition of Talc Powder on the Tensile Properties of Epoxy Material

Abstract

The stress-strain curve of Epoxy/Talc composite was studied using different ratio (0,5,10,15,20,25)% of Talc powder. The effect of composition ratio of Talc on the modulus of elasticity, toughness, max force of break, ultra tensile stress (UTS) as well as the stress and strain at break case were investigated for all prepared samples. The results show increasing the value of the modulus of the elasticity as the Talc ratio increased in the sample. The samples prepared using 10 and 25 % of Talc show max value of modulus of elasticity while the value is the less for the sample synthesis using 5% difference with the value of toughness for this composite. The value of UTS is increased to be max at 10% ratio of Talc and decreased when the composition ratio increased to be minima value at talc ratio of 25%, this is same behavior for stress fracture but the greatest force of break occurs at 5% which have high toughness and less value of elasticity.
