Some Physical Behavior of Epoxy /Lead Composites for Various Doses of Radiation


The study were to examine the feasibility of the effect of gamma irradiation on some physical properties, (elongation at break and tensile strength) using an Instron Tensile teste. A series of composites has been prepared by adding lead powder and lead shots with different masses to the epoxy resin. The effect of gamma irradiation on the tensile behavior of the points to a deterioration of the mechanical properties of composite due to the degradation and cross-linking reactions resulting from irradiation was examined. The observed results remarks that the changes in the color of epoxy composites, color varied from yellow up to dark brown gradually as a result of different radiation doses effect of radiation exposure to the composites.
