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.

本研究旨在通过对木材在极端条件下的劣化机理和耐久性的研究，为开发高功能木质材料提出新的思路和理念。(a)在海洋环境中，各种木质材料在一年内受到海洋蛀虫的严重攻击，而塑料即使在两年后也没有受到攻击。(b)在土葬环境下，对日本遗址的现场监测表明，残留木材是潜在的指标。此外，还讨论了一些因子的季节变化与木材在土壤中保存条件的关系。(c)空间环境适用材料可从木质原料中开发。(d)极地温度环境对阻燃剂处理木材的燃烧行为没有造成任何影响。
