摘要:
 研究阴香木材的密度、干缩性、弯曲强度、冲击韧性、硬度等主要物理力学性质。结果表明，基本密度、气干密度(含水率为12%)和全干密度分别为0.501、0.609 g/cm3和0.581 g/cm3，生材密度为1.215 g/cm3，气干密度属于国产木材的中等水平。全干差异干缩和气干差异干缩分别为1.59和1.86，弦向和径向干缩系数分别为0.495和0.362，弦向和径向干缩湿胀差异较大。抗弯强度75.6 MPa，顺纹抗压强度41.19 MPa，冲击韧性43.39 kJ/m2，端面、弦面和径面硬度分别为4 789.72、4 390.77 N和4 260.19 N。阴香木材的综合强度为116.79 MPa，属低等级材。
Abstract:
 The main physical properties of Cinnamomum burmannii woods,including the density,dry-shrinkage,bending strength,imapct toughness,hardness,etc.,were studied in this paper.As indicated by the results,the basic density,air-dry density ( with a moisture content of 12% ) and oven-dry density were 0.501,0.609 g/cm3 and 0.581 g/cm3,respectively,and the raw material density was 1.215 g/cm3,the air-dry density belonged to the medium grade level.The values of differential shrinkage of oven-dried and air-dried wood were 1.59 and 1.86,The radial and tangential shrinkage coefficient were 0.495 and 0.362,indicating that the difference of drying shrinkage and the wetting swelling in radial and tangential directions were significant.The values of bending strength and compressive strength parallel to grain were 75.6 MPa and 41.19 MPa.The toughness was 43.39 kJ/m2,the values of hardness on cross,tangential and radial surfaces were 4 789.72,4 390.77 N and 4 260.19 N,respectively.The general strength was 116.79 MPa,thus illustrating that the wood was of low quality.
