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.

这项研究的目的是有效利用纤维素纳米纤维（CNF）增强树脂在碳纤维增强塑料（CFRP）之间的层状之间，以增加其层间骨折韧性。为此，通过使用CNF增强树脂来增强层间骨折韧性的机制正在实验上。因此，调整了一些参数，例如纤维体积，树脂中CNF的光纤长度等，以找到获得树脂最佳性能的最有效方法。当前，开发了一种用于CFRP层压板中CNF增强树脂复合材料的技术。此外，还确定了在CFRP中间层中施加的CNF加固树脂量的最佳条件。
