This study was carried out to investigate the effect of steaming on mechanical properties of heat-compressed wood specimens. The specimens for this mechanical strength tests were prepared to super-heated steam treatment after compression to the radial direction of sonamu (Pinus densiflora). The specimen s size is 50(L)mm x 20(R)mm x 17(T)mm. Steaming temperature and treatment time is l20°c and 20, 40, 60, 80, 100 minutes, respectively. Modulus of elasticity(MOE) in compressive test is direccly proportional to steaming time. On the other hand, modulus of elasticity in bending test between steaming and not steaming after heat-compressed wood is similar irrespective of steaming time. The reason for this phenomenon is not clear yet.
