Influence of Graphene Oxide on Mechanical and Hydrophilic Properties of Epoxy/Banana Fiber Composites

Epoxy/banana fiber (EBF) composites with fiber length of 5–7 mm and fiber content of 5.0 wt.% were prepared by hand layup technique. Graphene oxide (GO) was dispersed at different concentrations (1.0 wt.%, 2.5 wt.%, and 5.0 wt.%) in the EBF matrix using cetyltrimethylammonium bromide (CTAB), and its effect on the mechanical and hydrophilic properties of the EBF composites was assessed. The highest tensile strength of 11 MPa, flexural strength of...
