人工林峦大杉木材的物理力学性质

Study on Physical and Mechanical Properties of Cunninghamia konishii Wood

  • 摘要: 对福建省引种的24年生峦大杉的木材物理力学性质进行检测,结果表明:峦大杉木材的气干密度为0344g/cm3、弦向全干干缩率6020%、弦向湿胀性6440%、吸水性237810%、顺纹抗压强度6004MPa、抗弯弹性模量7250810MPa、抗弯强度59840MPa、顺纹抗拉强度62800MPa;峦大杉的材质与杉木相近,应用方面可参考杉木,在木构件加工时,其安全系数可使用杉木的量值。

     

    Abstract: The wood physical and mechanical properties of 24 year old Cunninghamia konishii trees introduced and grown in Fujian Province were tested. The results indicated that the airdried wood density of C. konishii was 0344g/cm3, the tangential shrinkage ratio was 602%, the tangential wetswelling ratio was 644%, the water absorption rate was 237.81%, the compression strength parallel to grain was 6004MPa, the bend elastic modulus was 7 250.81 MPa, the bending strength was 59.84 MPa, and the tensile strength parallel to grain was 628MPa. The test results showed that the wood properties of C. konishii were quite similar with those of C. lanceolata. The usage of C. konishii can be referred to C. lanceolata. The safety coefficient of C. lanceolata wood could be applied to C. konishii wood while being processed as timber component.
