Abstract
The effect of adding graphite particles on the mechanical properties of epoxy-based material was studied using different particle sizes of (75, 53, 45) μm for graphite, with weight percentages of (0, 1, 3, 5, 7, 9)%. Fatigue tests showed that the epoxy-graphite composite recorded the highest value at 3% for all particle sizes. The highest value was at the particle size of 45 μm, followed by 53 μm and 75 μm. Compressive tests recorded the highest compressive strength value for the epoxy-graphite composite at 7% for particle sizes 45 μm and 53 μm. The highest value for the 75 μm particle size was at 5%.
