Hardness Analysis of Composite Materials Based on Epoxy Resin and Graphene

One material that is currently being developed is graphene. To determine the hardness value of graphene-based composite materials with 0.34% and 0.70% graphene composition. This type of research uses experimental methods, which is a way to find the hardness strength of graphene-based composite materials. From the results of hardness testing, the hardness level of graphene-based composite materials with a 0.34% graphene composition has an average hardness value of 766.88 HL while a 0.70% graphene composition has an average hardness value of 794.76 HL. It can be concluded from this research that the difference in the level of hardness of materials made from 0.34% and 0.70% graphene has a percentage difference of 3.5% with the hardness value of the 0.34% graphene composition being lower than the hardness value of the 0.70% graphene composition
