聚丙烯/亚麻纤维复合材料的性能研究

Study on Properties of PP/FF Composite

研究了亚麻纤维(flaxfiber,FF)的含量和马来酸酐接枝聚丙烯(MAH-g-PP)对聚丙烯/亚麻纤维(PP/FF)复合材料各项性能的影响,通过扫描电镜研究了复合材料的界面结构。结果表明:随着FF含量增大,复合材料拉伸强度、硬度和热变形温度提高;添加MAH-g-PP提高了复合材料力学性能和热稳定性,降低了复合材料吸水性。

Influences of flaxfiber（FF） loadings and adding of MAH-g-PP on various properties of PP/FF composite were studied and inteffacial morphology of the composite was studied by SEM. Experiment results indicated that as FF loadings increased, tensile strength, hardness, HDT of the composites increased. The mechanical properties and thermal stability of the composite were improved and its water absorption decreased by adding MAH-g-PP into PP/FF composite.
