The insert effect of cellulose nanofiber layer on glass fiber-reinforced plastic laminates and their flexural properties

Abstract

Cellulose nanofibers (CNF) have the potential to adhere glass fiber reinforced plastics (GFRP) without a decrease in their mechanical properties. In this study, we inserted two CNF layers between GFRP laminates and evaluated their flexural properties. With the insert of a single CNF layer, we revealed that even an extremely slight CNF (0.04 wt.%) addition, drastically increased the flexural strength and fracture elongation of epoxy resin by 130 % and 180 %, respectively.
