| Research Abstract |
The aim of the current research was to propose new ideas and concepts to develop high-functional woody materials based on the research deterioration mechanism and durability of wood under extreme conditions. (a) In marine environment various woody materials were heavily attacked by marine-borers within one year, whereas plastics were free from attack even after two-year exposure. (b) Under Soil-burial environment, the field monitoring at some Japanese ruins suggested the potential indices of residual wood. In addition, the relation between the seasonal variations of some factors and the conserving conditions of wood in the soil. (c) Space environment-applicable materials could be developed from raw woody materials. (d) Polar temperature environment did not cause any difference in combustion behavior of fire-retardants-treated wood.
