摘要

摘要: 利用注射成型制备了甘蔗渣纤维增强聚丙烯复合材料, 分析了纤维质量分数、注射成型条件以及添加物对复合材料力学性能的影响。结果表明, 随着纤维质量分数的增加, 材料的弯曲模量呈递增趋势。由于甘蔗渣纤维热降解的发生, 材料的力学性能随筒体温度的增加呈下降趋势。在模具温度90℃、注射间隔时间30s、不同的筒体温度185℃和165℃的成型条件下, 材料的弯曲性能和冲击强度分别呈现最大值。添加了马来酸酐改性聚丙烯后, 材料的弯曲强度和冲击强度得到了提高。

Abstract: The bagasse fiber reinforced polypropylene composites were fabricated by injection molding, and the mechanical properties of the composites were investigated in terms of the effects of fiber mass fraction, injection molding conditions and additive. The results indicate that the flexural modulus increases with the increase of fiber mass fraction. All the mechanical properties decrease with the increase of cylinder temperature due to the thermal degradation of the bagasse fibers. Under the conditions of mold temperature 90 ℃, 30 s interval, and different cylinder temperatures 185 ℃ and 165 ℃, the flexural properties and the impact strength show the maximum values, respectively. After the addition of maleic anhydride grafted polypropylene, the flexural strength and the impact strength are improved.
