Application of Time-Temperature-Humidity Superposition for thePrediction of Wood Properties During Long-Term Ageing

Abstract

Clear understanding of wood ageing is practically important for the appropriate maintenance and restorationof old wooden cultural properties as well as the quality enhancement of wooden musical instruments.However， it is difficult to discuss the effects of ageing by comparing new wood and aged wood， because thephysical properties of wood varies widely even in a same species. Many attempts have been made for theartificial acceleration of ageing by oven heating， but these have little reality because the effects of moistureare not considered in many cases. This paper introduces recent development of time-temperature-humiditysuperposition allowing precise prediction of wood ageing and artificial reproduction of aged wood.
