USING OF ARAMID FIBRES REINFORCED POLYSTYRENE FOR MANUFACTURING AUTOMOTIVES PARTS

The present research aim to study the effect of the reinforcement by fibres on mechanical properties of composite material consist of polystyrene resin reinforced by aramid fibres which can be used to manufactures auto motives parts such as bumpers .The properties included compressive and flexural strength , where the mechanical properties were extracted for polystyrene resin before reinforcement by fibres, then we reinforced the resin by different weight percentage from aramid fibres (%15,%30, %45, %60)and studied the effect on the above mechanical properties. The result obtained show An improvement in these properties after reinforcement by fibres The value of mechanical properties will increase with increasing percentage of reinforcement .Compressive strength increased from(92Mpa) to (163Mpa) and flexural strength from (0.08Gpa) to (0.165Gpa) for reinforcing percentages 0% and 60% respectively .
