The mechanical properties of the polypropylene-glass fiber compounds were evaluated compared to the polypropylene-polyamide6-glass fiber composites. The comparison of these four systems has been made over the 0-15 wt% PA6 content range. Also two different types of compatibilizers were tested on sample containing 10% wt polyamide6. The results indicate that the increasing the PA6 content leads to increases the tensile strength and Izod impact strength. The optimal amount of mechanical properties such as tensile strength, Elongation at breakage, and impact resistance were obtained in a composites containing 10% wt of polyamide6. PP-g-MH and Ethylene -Ethyl Acrylate-Maleic Anhydride Terpolymer as a compatibilizer, was evaluated. The results indicate that only PP-g-MH plays a compatibilizer role...
