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.
