竹木层积材层间剪切强度的研究

Interlaminar shear strength of bamboo-poplar epoxy laminates

采用短梁法对竹木层积材料层间剪切强度进行测试,结果表明,层间剪切强度随着层积材密度的增加而增大,当密度为0.95g/cm3时,达到最大值22.86MPa;其破坏模式可归纳为三种:胶层开裂、胶层竹材混合破坏和竹材破坏。

This study measures the interlaminar shear strength of bamboo-poplar laminating board by short beam shear test. The results show that horizontal shear strength rises up with the density of material and comes up to the peak value 22.86MPa at the density of 0.95g/cm3, its damage modes can be sumed up of three kinds： bonding layer failure, both of bamboo and bonding layer shear failure and bamboo shear failure.
