Reports from Wichita State University Advance Knowledge in Applied Polymer Science (Mechanical and Thermal Properties of Hierarchical Composites Enhanced by Pristine Graphene and Graphene Oxide Nanoinclusions)
By a News Reporter-Staff News Editor at Journal of Technology -- A new study on Applied Polymer Science is now available. According to news reporting originating in Wichita, Kansas, by VerticalNews journalists, research stated, "Epoxy resin nanocomposites incorporated with 0.5, 1, 2, and 4 wt % pristine graphene and modified graphene oxide (GO) nanoflakes were produced and used to fabricate carbon fiber-reinforced and glass fiber-reinforced composite panels via vacuum-assisted resin transfer molding process. Mechanical and thermal properties of the composite panels-called hierarchical graphene composites-were determined according to ASTM standards."
The news reporters obtained a quote from the research from Wichita State University, "It was observed that the studied properties were improved consistently by increasing the amount of nanoinclusions. Particularly, in the presence of 4 wt % GO in the resin, tensile modulus, compressive strength, and flexural modulus of carbon fiber (glass fiber) composites were improved 15% (21%), 34% (84%), and 40% (68%), respectively. Likewise, with inclusion of 4 wt % pristine graphene in the resin, tensile modulus, compressive strength, and flexural modulus of carbon fiber (glass fiber) composites were improved 11% (7%), 30% (77%), and 34% (58%), respectively. Also, thermal conductivity of the carbon fiber (glass fiber) composites with 4% GO inclusion was improved 52% (89%). Similarly, thermal conductivity of the carbon fiber (glass fiber) composites with 4% pristine graphene inclusion was improved 45% (80%)."
According to the news reporters, the research concluded: "The reported results indicate that both pristine graphene and modified GO nanoflakes are excellent options to enhance the mechanical and thermal properties of fiber-reinforced polymeric composites and to make them viable replacement materials for metallic parts in different industries, such as wind energy, aerospace, marine, and automotive."
