Effect of Lignocellulosic Materials on the Properties of Thermoplastic Polymer/Wood Composites

The effect of lignocellulosic materials on the board performance of thermoplastic polymer/wood composites was examined by using soft wood flours of 20 mesh- and 120 mesh-pass, steam-exploded beech flour, and two kinds of thermoplastic polymers, polyvinyl chloride and polystyrene. Steam-exploded wood flour was found to be one of the best lignocellulosic materials in terms of fracture strength and water resistance of the composite board. The properties of the composites are dependent not only on the lignocellulosic materials and polymers, but also on the average size of wood flour. Generally, a flour of 120 mesh pass gave composites of better performance than that of 20 mesh pass, but the tendency was reversed when steam-exploded beech flour was used.
