Abstract Scope |
The use of epoxy resin in composites reinforced with graphene oxide has been highlighted in the search for new materials. Graphene oxide provides composites with improved mechanical and thermal performance. However, using graphene oxide directly into the epoxy resin is difficult due to the Hummers manufacturing method that results in graphene oxide in an aqueous solution. Traditional hardening agents are not capable of polymerization in an aqueous medium on the epoxy resin. Therefore, the production of composites requires another drying step and the addition of other materials, such as isopropyl alcohol. The objective of this work is to use the modified imidazoline polyaminoamide (EFD 520) as a hardening agent comparing with the traditional pure epoxy (EFD 129). With the curing process successfully completed, mechanical impact tests of the Charpy and Izod type were performed. As a result, the epoxy resin cured with the polyaminoamide imidazoline had lower impact energy than the traditional epoxy. |
