| Outline of Final Research Achievements |
We examined changes in microstructure and tensile properties of abaca fibers. The lumen size became smaller after 10 and 15wt% NaOH treatment. Nonlinear stress-strain behavior was observed in the alkali-treated abaca fibers. Young’s modulus was found to decrease after alkali treatment with 10-15wt%NaOH.
We also made polylactic acid-base green composites reinforced with short abaca fiber, and evaluated their thermal property. It was found that the thermal conductivity of randomly-oriented short fiber composites also showed a similar dependence on the lumen size in the fiber as that of unidirectional composites.
