Go/rGo as reinforcing nanofiller in carbon fiber/epoxy resin composite systems
Interfacial interactions between matrix and reinforcement of composites influences greatly in final properties of the material. Carbon Fibers are
characterized for to have low interactions with resins when forming a composite material. In the present study, 0.3 wt% of GO/rGO were
incorporated in three systems of epoxy resin/carbon fiber as reinforcing fillers, trying to profit the chemical affinity between aromatics structures
of GO/rGO and polar interactions with epoxy resin. GO/rGO were characterized by XPS, TGA was performed on carbon fiber, epoxy resins and
composites obtained and SEM was utilized to observe composite samples in detail once mechanical tests were conducted. Composites
experienced noticeable enhancements by employing Bisphenol Epoxy (BP) cured with methyl cyclohexane-1,2-dicarboxylic anhydride
(MCHDA) as matrix and carbon fiber of 300 g/cm2
as reinforcement; Youngs modulus, rupture stress and elongation to fail- ure increased almost
twofold compared to non-modified composites by adding GO in the system and even superior boosts can be appreciated with rGO, which
additionally improves the flexural stress from 14.6 to 30.1 GPa.Postprint (published version
GO/rGO as reinforcing nanofiller in aramid fiber/epoxy resin composite systems
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
