In this paper, samples of composites consisting of polyvinyl alcohol-polyacrylamide and pomegranate peel were prepared by using the casting method. The polymers composites which the prepared have many applications. The concentrations of pomegranate peel are (0, 2,4 and 6) wt.%. The results show that the optical properties of polymer matrix are changed with the increase of the pomegranate peel concentrations .

This paper is to investigate the influence of adding 5,10 and 15 weight percentage silicon carbide particles on some mechanical properties of 6061 Aluminium alloy. The composites Al6061/SiC were prepared by stir casting technique.The results revealed that as the reinforcement content was increased, there were significant increases in the ultimate tensile strength, yield strength and hardness of composites accompanied by a reduction in its percentage of elongation. Microstructural studies have been carried out to understand the nature of structure.
