Injection molded biocomposite specimens were prepared by using four different weight percentages, i.e., 10%, 20%, 30%, and 40% of aspen ( L. and willow ( L.) wood particles in a biopolymeric matrix. Dog-bone test specimens were used for testing the physical, mechanical, and thermal properties, and microstructure of biocomposites. The tensile and bending strength changed with the change in weight percentages of wood particles and the bending stiffness increased with the increasing weight percentage of wood. In Brinell hardness, similar changes as a function of wood particle weight percentage were shown, and a relationship between hardness and tensile strength with wood content was also investigated. The prepared biocomposites could be an alternative for plastic-based materials and encourage the use of fast growing (aspen and willow) wood from short-rotation forests in biocomposites.
通过在生物聚合物基体中使用四种不同重量百分比（即10%、20%、30%和40%）的白杨（L.）和柳树（L.）木颗粒，制备了注射成型生物复合材料试样。采用狗骨形试样测试生物复合材料的物理、力学和热性能以及微观结构。拉伸强度和弯曲强度随木颗粒重量百分比的变化而变化，弯曲刚度随木重量百分比的增加而增加。布氏硬度也呈现出随木颗粒重量百分比变化的类似趋势，并且还研究了硬度与木含量之间的拉伸强度关系。所制备的生物复合材料可替代塑料基材料，并鼓励在生物复合材料中使用短轮伐期森林中快速生长的（白杨和柳树）木材。
