Abstract
The mechanical properties of araldite matrix composites incorporated with hybrid carbon - kevlar fibers were evaluated . There are indications that the incorporation of both fibers into a single matrix which is araldite resin will stabilize mechanical properties and lowering manufacturing costs . In this research the impact strength , tensile strength ,flexural strength ,and hardness were studied for composite material reinforced with hybrid fibers as a woven roving (°90-°0) with density (225g/cm3) and (285g/cm3) for carbon and kevlar fibers respectively . These fibers were mixed with araldite resin in different reinforcement percentage (20%,40%,60%) and the effect on the above mechanical properties were studied , where we see Improves in these mechanical properties after reinforcement by fibers The value of mechanical properties will increase with increasing percentage of reinforcement .
