Poly(Lactic Acid)(PLA)-reinforced kenaf bast fiber composites : the effect of triacetin.

In this article, the mechanical, morphological, and dynamic-mechanical properties of the blends of PLA and kenaf bast short fiber were investigated. The composites, with different fiber loading and triacetin content, were prepared by melt blending techniques using a Brabender internal mixer at 60 rp...
