Abstract:

The results of wood mechanical tests of Chinese fir (Cunninghamia lancelata (Lam.) Hook) belonging to 16 sampls show that in static bending, toughness, shear parallel to the grain and cleavage wood is more resistent to a force acting on its tangential sections than on its radial sections to a different extent except compressive force perpendicular to the grain. The cause of the difference induced is analysed.

Key words: Chinese fir, Wood mechanical property, Anisotropic behavour
