抄録

In this experiment the mechanical properties of old timbers were tested in comparison with new timbers to research the influence of age on the mechanical properties of wood. The materials used in the experiment have been 9 kinds of timbers taken from old temples in Japan. They have respectively been from 359 to 1,300 years old. These old temples are as follows. Horuji temple (about 1,300 years ago), Gokurakuin temple (about 1,200 years ago). Byodoin temple (about 900 years ago). Daihoonji temple (about 730 years ago), Rengeoin temple (about 700 years ago), Tomyojii temple (about 530 years ago), Kodaiji temple, Enmanin temple, Kyoogokokuji temple (about 350 years ago) respectively. I have also used 3 kinds of new materials from different places for the comparison. The species used in this test are all of HINOKI (Chamaecyparis obtusa ENDLICHER). The results obtained by this test are as follows. (1) The various mechanical strength are shown on table 7. (2) The influence of age on the mechanical properties of wood are shown in Fig.1. (3) The progress of change closely resembles the condition of wood heated in low temperature.
