Effect of acid solution on some Physical and Mechanical Properties of (Epoxy/polysulphide) Blends

The aim of present investigation is to evaluate the mechanical properties , (tensile, impact, and hardness) properties and physical properties. Acid absorption for (epoxy/polysulphide) specimens were prepared by open molding technique , with different ratios (95-5),(90-10),(85-15), and (80-20)% wei...

Description
Summary:The aim of present investigation is to evaluate the mechanical properties , (tensile, impact, and hardness) properties and physical properties. Acid absorption for (epoxy/polysulphide) specimens were prepared by open molding technique , with different ratios (95-5),(90-10),(85-15), and (80-20)% weight ratio. Impact strength (Charpy method) using showed a better value for (85-15)% ratio, so toughness increased and this optimum mixing ratio (OMR) was taken for tensile and hardness test before and after immersion in acid solution with different concentrations (0.1 N, 0.2 N, & 0.3 N) to evaluate tensile strength and Shore hardness D , 0.3 N had been affected all specimens more than (0.1 & 0.2)N, in each test Diffusion coefficient was calculated for each concentration.
