毛竹材性差异对胶合竹层板应力分级的影响
The effect of Phyllostachys pubescens f.lutea Wen property on the E-Rated classification of laminated bamboo board
摘要
Abstract
The paper analyzed the influence of materials in different positions of bamboo culm on the E-Rated classification of laminated bamboo board.We tested the density,bending strength and modulus from the bottom up to the bamboo culm.Laminated bamboo board was graded according to bending modules made from strips in different locations of bamboo culm.We found that the density,bending strength and modulus increased from the bottom to up of a bamboo culm.The density fluctuated gently between 3 and 9 m,and the bending performance was similar to those in the range of 1-5 m and 5-9 m,respectively.The laminated bamboo board E-Rated grade was closely related to the bending performance of bamboo materials at different locations of the culm,which could be divided into four grades.关键词
