Abstract
To develop utilization technology of wood resources, production of new materials from wood powder was tried. It was confirmed that molding of wood powder was possible by using self-adhesion ability of wood without using adhesive. For improvement of strength performance of mold materials, a preparation method of wood powder was examined. Wood was broken down in various conditions of temperature and moisture content. Mold materials were produced only from wood powder under steam processing of high temperature and high pressure, and the strength performance was investigated. It was confirmed that improvement of strength performance of mold materials was possible by preparing wood powder in the state of high temperature and high moisture content.
