Abstract

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 amount of impregnated phenolic resin. In addition, when the amount of impregnated phenolic resin was about 40% in these woodceramics, the two-time carbonized woodceramics showed higher weight (23.8%) and density (30.0%) than the one-time treatment.

고밀도 우드세라믹을 제조하기 위한 기초연구로서 수지함침율에 따라 제조된 1차 탄화 우드세라믹을 수지 재함침 후 2차 탄화하여 우드세라믹을 제조하고 그 물리적 성질을 조사하였다. 1, 2차 탄화 우드세라믹의 성질 비교에서 수지함침율이 증가함에 따라 2차 탄화 후 중량 및 밀도증가율은 감소하였고, 수지함침율 40%일 때 1차 탄화 시보다 중량은 23.8%, 그리고 밀도는 30.0% 증가하여 최고치를 나타냈다.
