Abstract
In order to consider the effect of production conditions of wood powder on the bending properties of wood powder molding material, wood was ground to powder under the conditions of different temperatures and moisture contents, then stick specimens were produced by injection molding method. The specimens were produced only from wood powder in the steam atmosphere using self-bonding ability of wood powder. To evaluate the bending properties of the specimens, modulus of elasticity and bending strength were examined. In case of wood particle produced under the condition of high temperature and high moisture content (100℃ and about 30%MC), tendencies for intercellular layer to be exposed on surface of a particle and for aspect ratio of particles to belarge were confirmed. And in that case, the specimen showed the highest value in modulus of elasticity and bending strength. It is highly probable that the improvement of the self-bonding ability of the wood powder and the increase of the aspect ratio take part in the improvement of the strength properties.
