Abstract
The dependence of mechanical characteristics (hardness and tensile strength) of polyurethane on the content of MgFeGa layered triple hydroxide additive and the electron beam irradiation dose is investigated. The optimal amount of layered hydroxides and the optimal irradiation dose, causing a substantial increase in tensile strength and hardness of polyurethane, are determined. Polyurethane modification by adding magnesium/iron/gallium layered triple hydroxides in the amount of 3 wt% causes an increase in tensile strength and hardness by 30.0 and 5.4%, respectively. Modification of pure polyurethane by irradiation with the optimal dose (100 kGy) promotes an increase in tensile strength by 27.1% and hardness by 4.6%.
