| Research Abstract |
It is of importance to investigate the degradation mechanism of antique wooden materials used for historical temples, buildings and crafts from the viewpoint of both wood science and archeology. In this paper, we applied FT-NIR spectroscopy to monitor the degradation process antique wood, that have been buried in Kiso Mountain for more than 1000 years. The physical, chemical and mechanical properties of the antique hinoki cypresses weresystematically measured. Compressive Young’s modulus of oven tried wood divided by oven-dried density, break strength, equilibrium moisture content significantly decreased as a function of ageing time, whereas crytstallinity increased.Partial least square (PLS) regression analysis was employed to predict these properties The prediction gave strong relationships between measured and predicted value for ageing time
