The purpose of this study is to effectively employ cellulose nanofiber (CNF) reinforced resin in between plies of carbon fiber reinforced plastics (CFRP) laminates to increase its interlaminar fracture toughness. To do so, the mechanism of enhancement of interlaminar fracture toughness by using CNF reinforced resin is being experimentally clarified. In this study, a technology for localizing CNF reinforced resin composites in CFRP laminates was developed. Besides, the optimal conditions for amount of CNF reinforced resin applied in the CFRP interlayer were also determined. The CNF reinforced resin was then applied to CFRP laminates with complicated internal structures to suppress its damages.
