Fiber association and network formation in PLA/lignocellulosic fiber composites. [PDF]

open access: yes, 2013
PLA composites were prepared in an internal mixer with a lignocellulosic fiber having relatively large aspect ratio. Fiber content changed between 0 and 60 vol% and the homogenized material was compression molded to 1 mm thick plates.
