| 摘 要： | 对竹材不同距地高度径向位置的弯曲性能进行了研究,并应用DENSE-LABX端面密度仪测定竹材沿端面的密度分布情况,分析了密度的变化与竹材弯曲力学性能的关系。结果表明:竹材的静曲强度(MOR)和弹性模量(MOE)沿径向均是从最内层竹黄处向竹青处逐渐增大,MOE的差异更加显著;竹材的弯曲性能随着密度的增大而增加,趋势接近于线性变化。

| Abstract: | In order to optimize the structural design of bamboo/wood composite manufacturing,and to supply some theory to manufacturing process.Bending performance at different height and radial location of the culm was analyzed.The density distribution was measured with the DENSE-LABX end density meter.The relation between the variety of density and bending performance was analyzed.The results showed that MOR and MOE increased both with the location from the inner to the outer of bamboo culm wall.Deviation of MOE was more notable.Bending performance of bamboo increased with its density,and the curve between them trended to be linear. |
