Abstract: An epoxy resin EP with backbone structure was obtained by curing o-cresol novolac epoxy resin with phenol novolac resin. The reinforced epoxy test specimens were prepared in the form of 45 × 35 mm², 10.0 mm thickness and adding four meshes of aluminium wires of 40 × 30 mm² with 5, 10, 15 and 20 wires of 0.2 mm to 1.0 mm diameters at 10mm from surface. The effect of the test temperature on the mechanical properties of the reinforced epoxy is carried out and investigated. The electrostatic charge is measured at a static loads ranging from 50 to 200 N at dry condition at various test parameters. A corrosion test is carried out and investigated on the produced reinforced epoxy composites using NaCl with concentration ranging from 0.01M to 1.0M at an immersion time of 50, 100, 150, 200 and 250 hrs at room temperature. Water sorption method is carried out to investigate the effect of the previous parameters on the reinforced epoxy composite properties.
