▎ 摘　　要

Epoxy/banana fiber (EBF) composites with fiber length of 5-7mm and fiber content of 5.0wt.% were prepared by hand layup technique. Graphene oxide (GO) was dispersed at different concentrations (1.0wt.%, 2.5wt.%, and 5.0wt.%) 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 11MPa, flexural strength of 55MPa, impact strength of 92J/m and contact angle of 57 degrees were recorded for the 5.0wt.% GO-reinforced EBF composite, compared with 5MPa, 27MPa, 38J/m, and 64 degrees for the EBF composite and 4MPa, 23MPa, 31J/m, and 65 degrees for neat epoxy, respectively. It was observed that GO was dispersed uniformly in the EBF matrix by the CTAB treatment, improving the mechanical and hydrophilic properties of the EBF composites.
