Effect of solvent on flexural properties and enhanced tensile properties of composite carbon black reinforced epoxy resin

Abstract

In the 20th century, epoxy resins have found great applications that are widely used in everyday life with the carbon group reinforcing to have better mechanical properties. In this research, we studied the mechanical properties of epoxy composites reinforced with carbon black composite materials. The main objective is to study the effect of solvents on the flexural properties of epoxy resin and tensile properties of epoxy composite materials reinforced carbon black. The results of the study found that 4 different polarity solvents that are ethanol (EtOH), Methanol, MeOH), Acetone and Methyl Ethyl Ketone (MEK) in 1 wt.% had no effect on the stress, Young's modulus, and stress at yield point in flexural property of epoxy resin. In addition, the composite materials reinforced with carbon black in 0.05, 0.2, 0.3, 0.4, and 1 wt.% affect the tensile properties. The composite materials reinforced with 0.3 wt.% of carbon black increase the stress at yield point to 33%.
