Abstract
This paper reports the mechanical properties of bending, compression and hardness of woodceramics manufactured at different carbonizing temperatures (600℃, 800℃, 1000℃, 1200℃ and 1500℃) in a vacuum sintering furnace using sawdust boards of Pinus densiflora, Pinus koraiensis and Larix kaemferi. The highest values of bending MOR (MORb) were 104 kgf/cm2 (1200℃), 91 kgf/cm2 (1500℃) and 86 kgf/cm2 (1500℃), the highest values of compression strength were 152 kgf/cm2(1200℃)), 160 kgf/cm2(1000℃) and 189 kgf/cm2(1000℃), the highest values of hardness were 2.00 kgf/mm2(800℃), 2.01 kgf/mm2 (1200℃) and 2.28 kgf/mm2 (1000℃) in P. densifora, L. kaemferi and P. koraiensis, respectively. The carbonizing temperature of 600℃ was not proper to the mechanical properties for three kinds of sawdust boards and the highest values of mechanical properties were different from the kinds of mechanical properties and species of sawdust boards. Therefore, it is necessary to manufacture woodceramics at a proper temperature for particular species of sawdust boards to obtain good mechanical properties.
