Abstract
In this study, we made polylactic acid-base green composites reinforced with short Manila hemp fiber, and evaluated their thermal property and moisture absorbing and desorption behavior. 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. Malila hemp fiber has a good humidity control ability, and thus the green composites reinforced by this Manila hemp fiber also show a similar functionality, namely humidity control ability.
