Compatibility between matrix and reinforcement plays an important role in final properties of composite
materials, which is why many works are focused in modify- ing interfacial interactions between both components to
achieve greater mechanical properties. In the present study, 0.3 wt% of GO/rGO particles are introduced in epoxy
resin/aramid fiber composites to evaluate the capacity of GO/rGO as reinforcing fillers. XPS, SEM, TGA, tensile and
flexural tests are utilized to characterize GO/rGO, aramid fiber, three epoxy resin matrix systems and all composites
obtained. Enhancements of mechanical properties up to 80 % were achieved by combining digly- cidyl ether bisfenol A
(DGEBA) + diglycidyl aniline (DGA) + m-xylendiamine matrix, aramid fiber reinforcement and GO/rGO.Postprint (published version
