Thermal and Natural Particles Addition Effects on the Mechanical and Physical Properties of Epoxy–Polyurethane Resin Blend Polymer

Aseel Kais Rasheed, Noor Kais Rasheed, Ismail Ibrahim Marhoon


In this study, natural particles were added to blend polymer resin. Composite material prepared from pistachio shells was added to epoxypolyurethane blend polymer. The weight ratio of additive for liquid polyurethane to epoxy was 12 wt.%. In addition, their mechanical and physical properties were studied depending on a range of variables, such as temperature (25 °C, 35 °C, 45 °C and 55 °C) and volume fraction (3%, 6%, 9% and 12%). Hardness, impact strength and thermal conductivity were studied. Results showed that the impact strength was increased and that the hardness and thermal conductivity values were reduced at high temperatures. Meanwhile, the impact strength and hardness increased and the thermal conductivity values decreased with increased volume fracture of pistachio shells particles.
