| Research Abstract |
ensile tests were conducted, and the fracture surfaces were observed with the SEM to explain for reduction of mechanical properties of Japanese larch timber under four drying methods and three exposure conditions. Brittle cases were often observed in Japanese larch specimens compared with Japanese cedar, and the high-temperature setting method brought more brittleness for Japanese larch timber. The results of bending tests for structural timber and small clear specimens indicated that drying methods was critical to mechanical properties of both, but exposure had little effects on them.
