A fibre glass reinforced polymer was developed, using epoxy resin as the matrix material and E-glass fibre as the reinforcement, by hand laying method. Different set of the composite were produced by varying the weight percentage (wt%) addition of the reinforcement to the epoxy resin as follows 10%, 20%, 30%, 40% and 50%. The polymeric composite so produced were subjected to various mechanical property tests as hardness, tensile, impact, tests. The hardness test was conducted using TQ SM1000 Universal Testing Machine, the tensile strength test was carried out on Hounsfield Tensiometer model while the impact test was carried out on Izod Impact Testing Machine. It was observed that the mechanical properties of hardness, tensile strength and impact strength were of higher values in the composites with different weight fractions of glass fibre than in unreinforced epoxy resin. It was also found out that the values of those mechanical properties increased directly proportional to the amount of weight percentage of the reinforcement in the composites with the highest of the values residing in the composite with 50 wt% of the reinforcement. The hardness value for GFRP composite with 50 wt% glass fibre reinforcement stood at 57 BHN, tensile strength at 332.7 MPa and impact energy value of 17.5 J/m 2 .
