摘要
以废旧玻璃钢粉（WFRP）为填料制备了聚乳酸（PLA）基复合材料,通过力学性能测试和热重分析,研究了WFRP含量对复合材料性能的影响。结果表明：随着WFRP用量的增加,复合材料的拉伸强度下降,冲击强度先升高后降低,弯曲强度和洛氏硬度逐渐增大,热稳定性逐渐提升。
The polylactic acid/waste glass fiber reinforced plastic powder（PLA/WFRP） composites were prepared. The effects of WFRP content on properties of the PLA/WFRP composites were investigated by mechanical testing and thermogravimetric analysis. The results show that： with the increasing of WFRP content, the bending strength, Rockwell hardness and thermal stability increase, however, the tensile strength decreases, and the impact strength increases first and then decreases.
