| Popis: | In order to obtain basic data to use wood for a plastic substitute, the flow property of wood was examined. Usually, in the studies aiming at using wood for a plastic substitute, wood is powdered before molding. Whereas in this study, the raw material was not powdered to save time and energy for a powdering process. The fluidity of wood in bulk state was examined by a capillary rheometer. The fluidity improved as the moisture content increased. Oven-dried wood showed poor fluidity. However, it was possible to flow oven-dried wood by thermally decomposing its component. The qualities of extruded wood also depend much on the moisture content of the raw materials. Fiber cells (tracheids) were hardly observed on the cross section of the extruded material obtained from oven-dried wood, whereas they are clearly observed on the cross section of the specimens obtained from water-saturated wood. |
