従来型の繊維強化プラスチック(FRP)に対し環境負荷の少ない「グリーンコンポジット」の実用的な成形プロセスの確立が切望されている。本研究では、天然繊維およびポリ乳酸を原料とする長繊維強化樹脂(LFT)ペレット製造および射出成形による複合材製造法を対象に、複合材の力学的特性に対する繊維の含有水分や熱劣化の影響、繊維分散の効果等を把握し、高い特性を発揮させるための成形プロセスおよび諸条件を提示した。 / 'Green Composites' have been attracting attention due to their high sustainability and carbon neutrality. This study investigated the preparation process for composites of long jute fiber reinforced polylactic acid by LFT-pellet manufacturing method followed by injection molding. The author explored effect of several factors, such as moisture in fiber, heat decomposition of fiber at processing and the level of fiber dispersion in matrix resin, on mechanical properties of composites. The author eventually proposed the optimized process and operating windows for attaining higher mechanical properties of composites. / 博士(工学) / Doctor of Philosophy in Engineering / 同志社大学 / Doshisha University
