It is shown that approximately 2wt% of graphene in the matrix of a unidirectionally-reinforced carbon fiber epoxy composite leads to a significant enhancement in mechanical properties. Particularly, it is found that the axial stiffness of the composites is increased by 10GPa accompanied by an increase in axial strength of 200MPa.
How Amira-Avizo Software is used
Visualization and analysis was performed in Thermo Fischer Avizo software (version 9.2.0), employing manual segmentation to analyze graphene platelets and carbon fibers. The orientation of the axial direction of the fibers and the normal direction of the graphene flakes were both determined in Avizo, using the Label Analysis toolbox.
