Outline of Research at the Start

In this study, a sustainable cellulose nanofiber reinforced resin will be effectively employed to increase the interlaminar fracture toughness in carbon fiber reinforced plastic (CFRP) laminates with complex internal structures, to suppress the damage propagation that always contributes to the failure of the structures.

Outline of Final Research Achievements

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.

Academic Significance and Societal Importance of the Research Achievements

The introduction of CNF reinforced resin in CFRP laminates demonstrates that it is possible to prevent the development of delamination that leads to material failure. This represents a groundbreaking technology that significantly contributes to the broader application of composites.
