라디에타소나무 열압밀화 목재의 경도와 치수안정성 -압체 온도와 시간의 영향- = Hardness and Dimensional Stability of Radiata pine (Pinus radiata D.Don) Heat-Compressed Wood -Effect of Press Temperature & Time-

다국어 초록 (Multilingual Abstract)

It was investigated the hardness and dimensional stability of heat-compressed wood by compression temperature and time. The surface hardness of heat-compressed wood increased with increasing compression temperature. The lowest hardness value (5.0 N/mm2) was observed in the temperature 70℃ while the highest value (15.6 N/mm2) was obtained in compression temperature 220°C Dimensional recovery test results showed that fixation of compression set improved with increasing compression temperature. However, the fixation effects were negligible by press time. Contact angle increased with increasing press temperature and time.
