Study on physical and mechanical properties of Cunninghamia konishii Wood.
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 0.344 g/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 6.004 MPa, the bend elastic modulus was 7 250.81 MPa, the bending strength was 59.84 MPa, and the tensile strength parallel to grain was 62.8 MPa. 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.
