以稻壳粉和非医疗废弃物作为原料，采用挤出–注塑工艺制备回收塑料／稻壳粉木塑复合材料，研究了稻壳粉的粒径、含量以及玻璃纤维对复合材料力学性能的影响，用扫描电子显微镜对复合材料的断面进行了观察。结果表明，回收塑料／稻壳粉木塑复合材料的力学性能随稻壳粉粒径的增加先上升后下降，随稻壳粉含量的增加而提高。当稻壳粉质量分数为50%，粒径为425μm时，回收塑料／稻壳粉木塑复合材料综合力学性能最好。当用偶联剂处理稻壳粉和玻璃纤维后，相对于纯回收塑料，复合材料的拉伸强度提高了82.01%，拉伸弹性模量提高了414.66%，弯曲强度提高了152.62%，弯曲弹性模量提高了436.99%。

Recycled plastic/recycled plastic rice husk powder composites were made by extrusion and injection molding process with rice husk powder and nonmedical recycled plastic. The influence of size,content of rice husk powder and surface treatment on the mechanical properties of the composite were investigated. The morphology of the composite was observed by SEM. The results show that the mechanical properties of the recycled plastic/rice husk powder composites first increase and then decrease with increase of the size of rice husk powder,and increase with increase of the content of rice husk powder. Mechanical properties of the composites are best when the content of the rice husk powder with 425 μm is 50%. Compared with recycled plastic,tensile strength,tensile modulus,flexural strength and flexural modulus of the composites reinforced by glass fibre increased by 82.01%, 414.66%,152.62%,436.99%.
