The present work investigates the performance of graphene oxide (GO) functionalization on the tensile properties of curaua fiber (CF) reinforced epoxy matrix composites. Four groups of samples of epoxy composites reinforced with continuous and aligned curaua fibers in the percentage of 30 vol% were made: epoxy matrix reinforced with CF (CF/Epoxy), epoxy matrix reinforced with CF functionalized with GO (GOCF/Epoxy), epoxy matrix functionalized with GO reinforced with CF (CF/GOEpoxy) and both CF and epoxy matrix functionalized with GO (GOCF/GOEpoxy). The objective was to compare the results, in terms of mechanical properties, obtained by the addition of graphene oxide on the fibers and the matrix. In order to obtain parameters such as maximum stress (σmáx), Young’s Modulus (E) and maximum strain (ε), as well as stress-strain graph. The combination treatment of GO and CF displayed an effective enhancement on mechanical properties.
