Effect Of Sunflower Husk Particles Added To Polyurethane Polymer Matrix Composite

In this paper experimental investigations were conducted to demonstrate the effect of natural particles used as a reinforcement material on polyurethane resin. The effect of sunflower husk particles used as a reinforcement material on tensile strength elasticity modulus and water absorption with different weight fractions 2 4 6 8 and 10 and particle grain sizes 53 75 and 106 m were investigated. The addition of up to 10 sunflower husk as reinforcement materials to polyurethane resin increased the tensile strength and elasticity modulus of the prepared composite material. However the decrease in reinforcement material grain size led to the increase in tensile strength elasticity modulus and water absorption. Therefore results were considered superior in terms of composites containing reinforcement material with 53 m. Finally the best result for tensile strength elasticity modulus and water absorption was obtained by adding 10 sunflower husk as a reinforcement material to polyurethane resin.
