205401 ケナフ繊維強化PLA複合材の成形とその機械特性評価(一般01 材料科学・材料力学5)

抄録

In this study, hot-melting mixture followed by hot-pressing molding was applied to the processing of short-random fiber reinforced composites made of kenaf bast fibers as reinforcing agent and poly(lactic acid), PLA, as matrix resin. The effects of fiber content and fiber alkali treatment on the composite mechanical properties were mainly examined. Notch effect on the static ultimate strength of the present composites was also discussed. As a result of the present tensile test, kenaf fiber introduction into PLA resin could be found to improve the composite mechanical properties, especially in case of notched specimens, which implied that kenaf fiber would certainly play a role of reinforcing agent.
