고밀도 우드세라믹 제조를 위한 기초연구로서 수지함침율 60%인 톱밥보드를 이용하여 탄화온도별로 제조된 1차 탄화 우드세라믹을 수지 재 함침한 후 2차 탄화하여 우드세라믹을 제조하고 그 물성을 조사하였다. 1, 2차 탄화 우드세라믹 성질 비교에서 탄화온도가 높아질수록 2차 탄화 후 중량 및 밀도증가율은 감소하였고 탄화온도 $600^{\circ}C$일 때 1차 탄화 시보다 중량은 21.7%, 그리고 밀도는 1차 탄화 시 $0.68g/cm^3$에서 2차 탄화 시 $0.82g/cm^3$로 20.6% 증가하여 최고치를 나타냈다.

Repeated impregnation and carbonization processes were performed to prepare high-density woodceramics using a sawdust board. The physical properties were investigated to confirm morphological and structural changes of one-time and two-time phenolic resin-treated and carbonized woodceramics. As comparing between one-time and two-time carbonized woodceramics, the weight and the density of the two-time carbonized woodceramics decreased with an increase of the carbonization temperature. When the carbonization temperature was $600^{\circ}C$, the weight increased by 21.7% and density increased by 20.6% from $0.68g/cm^3$ to $0.82g/cm^3$, respectively, as a maximum value.
