| 摘 要： | 以拉伸流变为主的叶片挤出机与传统的螺杆挤出机有很大的不同,螺杆挤出机是以剪切流场为主的加工方式,而在叶片挤出机中则是以拉伸流变起主导作用。利用自主研发的叶片挤出机制备了剑麻纤维(SF)/聚丙烯(PP)复合材料。探讨了叶片挤出机加工转速以及SF含量对物料在挤出机中停留时间以及复合材料力学性能的影响。结果表明:物料停留时间随加工转速升高呈非线性减少趋势,随SF含量升高呈非线性增加趋势;在相同的SF含量下,复合材料的拉伸强度和拉伸模量随着转速的提高而增加,当转速提高到90 r/min时,拉伸强度和拉伸模量分别比转速为30 r/min时提高了21.3%和11.6%;在相同转速下,复合材料的拉伸强度随着SF含量增加而降低,而拉伸模量则随SF含量增加而增加。

| Abstract: | Vane extruder dominated by elongational deformation field was very different from the traditional screw extruder which was based on shearing deformation field.In this paper,sisal fiber(SF)reinforced polypropylene(PP)composites were prepared by the novel self-made vane extruder.The effects of rotating speed and sisal fiber content on residence time of materials and composites mechanical properties were investigated.The results showed that:residence time of materials decreased linearly with the rising of rota... |
