摘要

以刻痕和无刻痕两种工艺制备的竹展平板为研究对象,重点分析两种竹展平板的尺寸、物理力学性能及微观结构特征。结果表明:两种竹展平板的翘曲度均与板材厚度呈正相关关系,无刻痕竹展平板的密度和抗弯强度、顺纹剪切强度和抗弯弹性模量均高于刻痕竹展平板;无刻痕竹展平板在制备过程中仅有部分细胞压缩而无损伤,从而保留了竹材原有的结构,具有良好物理力学性能。

Abstract

Bamboo flattened board made with groove and without groove processing methods were studied. A comparative study was mainly conducted on the dimensional size,mechanical and physical properties and micro characteristics. Results indicated that the density, modulus of rupture, shear strength and modulus of elasticity of bamboo flattened board made without groove were higher than that made with grooves. Warpage of both flattened boards were positively correlated with the board thickness. However, warpage of non-groove flattened board was lower than the other. The better physical and mechanical properties of non-groove flattened board were related to the fact that the bamboo cells are not damaged and only partially compressed during the preparation process, thereby retaining the original structure and performance of bamboo.
