Epoxy composites are prepared using carbon nanotube (CNT) and oxyfluorinated powdered-carbon fiber (PCF) as reinforcements to enhance mechanical properties of composites. Tensile strength of PCF and CNT reinforced epoxy composites are relatively higher than that of epoxy composites reinforced CNT only. Also, the tensile and impact strength of epoxy composites added CNT and oxyfluorinated PCF are improved by respectively 112% and 35% than those of neat epoxy. These results are ascribed to increased interfacial adhesion of PCF with epoxy resin due to enhanced polarity and roughness of PCF-surface by oxyfluorination.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
