| Abstract: | The chemical. physical and mechanical properties of compression wood and opposite wood of branches from Masson pine have been determined and compared with the properties of normal stemwood in this paper.The results demonstrate that there are marked differences among three types of wood tissues in chemical composition. in degree of relative crystallinity of celluose. in density. in shrinkage and swelling, in water absorption. in compression strength parallel to grain. in static bending strength and its modulus of elasticity. |
