In this study, tensile properties of carbon fiber reinforced polymers(CFRP) with and without epoxy resin were compared by direct tension test. Although the strength contribution of resin is generally neglected because it is relatively infinitesimal and hard to be evaluated on-site application, resin enables CFRP itself to have higher strength and stiffness by arranging the layout of carbon fiber bundle, by decreasing the stressed effective length and by stress redistribution between fibers.
