A Comparative Study on the Bending Strength of European Spruce and Fujian Chinese Fir
Abstract
This paper compared the bending properties of European spruce (Picea abies (L.) H. Karsten) and Chinese fir (Cunninghamia lanceolata (Lamb.) Hook.) with differing densities and knot patterns to identify the most appropriate uses for the latter species. As expected, reduced density and increased knot size negatively affected the modulus of elasticity (MOE) and the modulus of rupture (MOR) of both species. The MOEs of European spruce were higher than those of Fujian Chinese fir and were higher in samples without knots. The effect of knots on bending strength was more pronounced in European spruce. The results indicated that Fujian Chinese fir and European spruce could be substituted for each other in some less-demanding structural applications, which helps improve the utilization of the latter species.
