文摘

The aim of this study was to evaluate the influence of Neosinocalamus affinis bamboo culm height on selected properties of original bamboo and the mechanical properties of bamboo plywood (BP). The results indicated that vascular bundle density, fiber proportion, specific gravity and compression strength parallel to grain (CSPG) increased from culm bottom to top. Bamboo culm height could significantly affect the mechanical properties of the BP. The shear strength (SS) of the BP decreased with increasing culm height, while the compressive strength (CS) increased. The maximum modulus of rupture (MOR) and tensile strength (TS) was observed at middle portion of culm. Significant correlation was found between vascular bundle density, specific gravity, culm wall thickness of original bamboo and the CS, SS of the BP.
