Effect of cellulose nanofiber content on the tensile and tensile shear characteristics of cellulose nanofiber reinforced composite resin

Abstract

In this study, cellulose nanofiber (CNF) is introduced to overcome the shortcomings in waterborne epoxy resin such as low mechanical properties and applicable temperature. Benefited by the significant mechanical properties of CNF, the new composite material is supposed to possess better properties both on strength and toughness, thermal and dimensional stability etc. The composites were prepared from a waterborne epoxy emulsion and a CNF water suspension through mechanical agitation and film casting. Scanning electron microscope is used to observe the dispersion of the filler. Tensile test and tensile shear test are conducted to evaluate the mechanical performance.
