Such differences could be due to several parameters such as the
variety of wood used (biochemical composition, microstructure), the
geometry of the filler (fibres, powder) and the processing parameters
(shear rate, temperature). In addition, the wood-fibre reinforced
biocomposites tested in the present study are made up of a blend of unknown
percentages of PHA and PLA, including unknown additives,
which complicates any straightforward comparison.
