| 摘 要： | 以聚乳酸(PLA)为基体,木粉为填料,分别采用热压成型和注塑成型方法制备了PLA/木粉复合材料。实验研究结果表明:当木粉用量由20%增加到60%时,PLA/木粉复合材料的拉伸强度由41.83 MPa降至15.96MPa;弹性模量由1 035.96 MPa降至283.43 MPa,断裂伸长率由7.04%降至1.73%。 |

| Abstract: | Selecting PLA as matrix resin and wood powder as filler,Poly(lactic acid)/wood powder composites were prepared by hot-forming molding and injection molding.The results show that: with increasing of wood powder content from 20% to 60%,the tensile strength of PLA/wood powder composites decreases from 41.83 MPa to 15.96 MPa,the modulus of elasticity decreases from 1 035.96 MPa to 283.43 MPa,and elongation at break decreases from 7.04% to 1.73%. |
