Abstract

In order to investigate the distribution rules of horizontal density in Chinese fir （Cunninghamia lanceolata） oriented laminated stick lumber （OLSL）， non-destructive testing was performed by computed tomography （CT） detection. The results were as follows：（1） CT detection could vividly and intuitively reveal the distribution characteristics of vertical and horizontal density in Chinese fir OLSL. The densities in surface plane and bottom plane were higher than that in the central plane， and that densities varied significantly in each joint. （2） Size of wood sticks， combined state in each joint and degree of forming uniformity had great influence on the distribution characteristics of horizontal density in Chinese fir OLSL. Compared with oriented strand board（OSB） and particleboard， the characteristic of stick-shaped structure in Chinese fir OLSL was more obvious under CT detection. ［Ch，5 fig. 17 ref.］
