STUDY THE EFFECT OF ADDITION OF NATURAL AND SYNTHETIC MATERIAL ON SOME OF MECHANICAL PROPERTIES OF UNSATURATED POLYESTER

Chemical

Abstract

In this work unsaturated polyester resin was modified with a Peach waste product of peach (natural) and novolac (synthetic) polymer. With weight percentage (0, 1.5, 3.5, and 5%). Some mechanical properties such as impact, tensile, and hardness conductivity as well as dielectric constant were studied. The results obtained that the best value of impact strength obtained at 5% from peach waste. Hardness Test gave proportional relationship with the peach waste percentage while it increased by 1% for novolac. Tensile strength gave the best value at 3.5% and tensile modulus at 1.5% of peach waste. Dielectric constant increases with the increasing percentage of added materials. The thermal Conductivity decreasing with an increase percentage of novolac particles while it decreased at 1.5% for peach.
