Study of Some Mechanical Properties for Polymeric Composite Material Reinforced by Fibers


The objective of this research is to study the effect of changing the reinforcement percentage by fibers on Mechanical properties, for composite material consists of conbextra epoxy (EP-10) resin reinforced by biaxial woven roving kevlar fibers (°45-°0) with density (340 g/cm3) which included impact strength , tensile strength , flexural strength and hardness Where the Mechanical properties were extracted for phenol formaldehyde resin before reinforcement by fibers, then we reinforced the resin by different weight percentage from Kevlar fibers(20%,40%,60%) and studied the effect on the above mechanical properties as illustrated in the diagrams .
