| Research Abstract |
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.
