| Abstract | ||
| The extrution method was different used to prepare melt blends of polypropylene (PP) and high density polyethylene (HDPE), after extraction the mixture were molded into sheets and left in air to cool. The samples of thickness (5mm) were cut to preform tensile test according to (ASTM D638). All the samples were subjected to gamma irradiation in presence the oxygen. The absorbed doses were ( 50, 100 and 150 Gy) at irradiation dose rate 19.8 rad/min, the tensile test preformed for non-irradiated and irradiated samples, then from the stress-strain curves we obtained the value of elongation at maximum, tensile strength and young's modulus. The result showed that there is significant effect of the blended rates and the radiation doses on the mechanical properties of the polymers. | ||
