Composite resin is one of the most important materials used in all industrial and medical fields nowadays, but it has many properties and advantages that distinguish it from metals. Many problems appeared previously due to the materials used and to overcome these problems, A composite resin with great physical and mechanical properties and compatibility has been developed. Composite resins are resin filled with high compressive strength, corrosion resistance, light weight, ease of application and high transparency. The aim of this study is to demonstrate the improvement of mechanical properties represented in tensile strength, fatigue life, impact resistance and hardness For polymeric materials such as epoxy after adding nanomaterials (graphene).
