| Abstract | ||
| Experimental investigations had been done in this work to demonstrate the effect of graphite filler contents on the mechanical and tribological behavior of (30% volume fraction) glass-polyester composite system. The stress-strain relations, modulus of elasticity, yield stress, ultimate tensile strength and ultimate compression strength were studied according to ASTM-D 638-87and ASTM-D 695 to present the composite mechanical behavior. The wear rate and wear resistance were investigated according to ASTM-D 5963 using pin on disc machine to present the composite tribological behavior. The results showed that the mechanical and tribological properties behavior was improved when the graphite filler content was increased up to 7.5% and then decreased after that. At 7.5% filler content the modulus of elasticity, yield stress, ultimate tensile strength, ultimate compression strength and wear resistance increased by (41%, 64%, 24%, 60% and 38%) greater than unfilled composite, while the wear rate was decreased by 27% less than the unfilled one. | ||
