Effect of Heat Treatment Temperature and Time on Sound Absorption Coefficient of Larix kaempferi Wood [PDF]
학위논문 (석사)-- 서울대학교 대학원 : 산림과학부 환경재료과학전공, 2016. 8. 여환명.목재는 다양한 재색과 문양을 지니고 가공이 용이하며 타 재료에 비해 비교적 높은 비강도를 가져 건축 인테리어 재료로서 많이 사용되어왔다. 특히 목재에 고온의 열을 가해 목재의 구성성분을 변형시킴으로써 성질을 개선한 열처리 목재는 소수성이 증가하여 치수안정성이 개선되고 별도의 표면처리 없이도 고급스러운 재색의 연출이 가능하다는 장점을 가져 새로운 건축 인테리어
