【摘要】 利用硅烷处理的甘蔗渣纤维填充无规共聚聚丙烯制备了复合材料,研究其力学性能与相态结构。结果表明:在甘蔗渣用量为10～15份时,用硅烷KH570处理的甘蔗渣制备的复合材料较直接填充物的拉伸强度与冲击强度各提高30％以上;试样结晶更完善,纤维在树脂中分布更均匀。更多还原

【Abstract】 A kind of composite material was prepared through filling propylene random copolymer (PPR) with bagasse fiber that was subject to surface treatment by silane. The studies on mechanical properties and phase structure of the composite reveal that in the case of adding 10 - 15 parts of bagasse treated with silane (KH570) into 100 parts of PPR, both tensile strength and impact strength of the composite increase by over 30%, crystallites of the composite specimen get more perfection and dispersion of the fibers in the resin become more homogeneous, compared with its counterpart filled with untreated bagasse.更多还原
