THIS RESEARCH was an attempt to illustrate the correlation between parameters of extrusion technique (screw speed) which was used to produce conventional and hybrid reinforced polypropylene composites and their optical and physical characteristics. The obtained results demonstrated the responses of hybrid reinforced composites were more stable and higher than those of conventional reinforced composites. Furthermore; the density and optical traits of hybrid composites were influenced extremely by the screw speed variation (reduction). The syndiotactic polypropylene was used as a matrix while talc and graphite were used as reinforcing agents (fillers) to prepare diverse weight percentages of reinforced polypropylene composites.
