Abstract

The study was carried out to investigate the physical (Density, Percentage of latewood, Percentage of pore zone, Mean annual ring width) and mechanical (Compressive strength parallel to the grain, Compression perpendicular to the grain, Shearing strength) properties of some major northern softwoods and hardwoods. The physical and mechanical properties of each species are summerized as Table 2 and the relationship between physical and mechanical factors are discussed. The results of this study were as follows: Density and percentage of latewood are closely related to physical and mechanical properties, but percentage of pore zone and mean annual ring width are remotely related to physical and mechanical properties.

북양산(北洋産) 주요(主要) 침(針), 활엽수재(闊葉樹材)의 물리적(物理的) 성질(性質)(밀도(密屠), 만재율(晩材率), 공권율(孔圈率), 평균년수폭(平均年輸幅))과 역학적(力學的) 성질(性質)(종압축강도, 횡압축강도, 전단강도에 관하여 연구(硏究) 조사하였다. 이 실험(實驗)의 연구(硏究) 결과(結果)는 다음과 같다. 밀도(密度)와 만재율(晩材率)은 물리적(物理的) 역학적(力學的) 성질(性質)과 밀접(密接)한 관계(關係)를 나타낸 반면, 공권율(孔圈率)과 평균년수폭(平均年輸幅)은 물리적(物理的) 역학적(力學的) 성질(性質)과 거의 관계(關係)가 없음을 나타내었다.
