| 摘 要： | 通过研究木粉含量对杨木粉-HDPE复合材料密度、吸水率、力学性能和流变行为的影响，结果发现：木粉含量由50%增加到70%时，复合材料的密度增大了15%，吸水率变大，弯曲强度提高了10%，弹性模量提高了约78%，但冲击强度下降了32%；流变研究表明，随着木粉含量增加复合材料的类固体行为更加显著。

| Abstract: | The effect of wood powder content on density,water absorption rate,mechanical prperties and rheological behavior of wood powder/high density polyethylene（HDPE） composites was studied.The results showed that when wood powder content was increased from 50% to 70%,the water absorption rate of HDPE composite was promoted,the density flexural strength,and elastic modulus was increased by 15%,10% and 78% ,respectively,whereas the impact strength was decreased by 32%.The rheological analysis indicated that the solid like behavior of HDPE composite became more significant with the increase of wood powder content. |
