Abstract
In this paper, prepare a set of ternary polymer blend , consisting of thermosets material which is (unsaturated polyester resin (UP)) and thermoplastic material (poly methyl methacrylate(PMMA)) and elastomers material which is natural rubber material (Natural Rubber (NR)) by hand lay-out technique. the basis material was prepared from the blend of binary polymeric materials (polyester (UP) 98% with natural rubber (NR)% 2)) then the material of (poly methyl methacrylate( PMMA)) was added by weight % (0,5,10,15) to binary polymer blend and according to the following formula: [ (100-X) % UP: X% PMMA) + 2% NR]. The research study included the effect of addition of weight percentages of poly (methyl methacrylate) PMMA) on the blends properties ternary polymer blend, and test the mechanical & physical properties like (the tensile strength and modulus tensile elasticity and compressive strength, and flexural strength , impact and fracture toughness and hardness and thermo- physical properties like thermal conductivity and thermal diffusivity beside specific heat) , all of these tests were conducted under laboratory temperature, the results showed that the values (tensile strength and modulus tensile elasticity, flexural modulus and impact strength and fracture toughness and hardness and thermal properties thermal conductivity and specific heat) increases with the weight ratios of the (poly methyl methacrylate) in tri- polymer blend. While values the compressive strength, flexural strength and thermal diffusivity decreases with the increase in the weight ratios of the (poly methyl methacrylate(PMMA)) in the the polymeric blends.
