USING OF FIBER COMPOSITE OF POLYPROPYLENE TO MANUFACTURING CARS BUMPERS

This research aims to manufacturing cars bumpers from polypropylene resin reinforced by it glass fibers with different reinforcement percentage (10%,30%,50%,70%) and study the impact strength and compressive strength for obtained composite material .An Improvement was happened in these properties after reinforcement by fibers The value of mechanical properties will increase with increasing percentage of reinforcement . Impact strength increased from (85Kj/m2 ) to (498Kj/m2 ) and compressive strength from (51Mpa) to (310Mpa) for reinforcing percentages 0% and 70% respectively.
