We developed novel technique to apply very thin additional fibers such as micro-fibrillated cellulose(MFC) to improve the mechanical fatigue properties with low thermal expansion of conventional composites based upon polymer as matrix and long fibers as main reinforcement, respectively. In fabrication, agglomeration of micro-fibrillated cellulose which was utilized as the "third material" in the liquid resin was adequately prevented by a dispersion technique with shear in very thin layer. The results showed that mechanical properties were improved by that hierarchy of reinforcement was created around the interphase due to the relative difference in scale between micro-sized fibers and reinforcing main fibers.

我们开发了一种新的技术，应用非常薄的附加纤维，如微纤化纤维素（MFC），以改善机械疲劳性能与低的热膨胀的传统复合材料的基础上聚合物作为基体和长纤维作为主要增强体，分别。在制造中，作为液体树脂中的“第三材料”的微原纤化纤维素的附聚通过在非常薄的层中具有剪切的分散技术被充分地防止。结果表明，由于微米级纤维与增强主纤维在尺度上的相对差异，在界面附近形成了增强层次结构，从而提高了复合材料的力学性能。
