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. Therefore, some parameters such as the fiber volume, fiber length of CNF in the resin, etc. are adjusted to find the most effective way to obtain optimum performance of the resin. Currently, 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.

摘要本研究旨在探讨在碳纤维复合材料层合板层间加入纤维素纤维（CNF）增强树脂，以提高其层间断裂韧性。为此，通过实验阐明了使用CNF增强树脂增强层间断裂韧性的机制。因此，一些参数，如纤维的体积，纤维长度的树脂中的CNF，等进行调整，以找到最有效的方法，以获得最佳的性能的树脂。目前，开发了一种在CFRP层压板中局部化CNF增强树脂复合材料的技术。此外，还确定了CFRP夹层中CNF增强树脂的最佳用量。
