摘要
通过优化碱处理工艺条件改善苎麻纤维结构和性能,同时对醋酸纤维素进行改性处理,制备了苎麻纤维增强醋酸纤维素复合材料。通过性能测试和扫描电镜观察发现:碱处理既提高苎麻纤维强度和模量,又对苎麻纤维有韧化作用,还提高纤维表面的吸附能力,从而提高苎麻纤维/醋酸纤维素基复合材料剪切强度和弯曲强度。
By an optimization processing of alkaline treatment to improve the structure and properties of ramie fibers, and by introducing some additives into the cellulose acetate to improve its processability, a new kind of composite, ramie fiber reinforced cellulose acetate,was fabricated. The results show that the tensile strength,tensile modulus,toughness and surface adsorption ability of the ramie fiber can be improved when the ramie fiber is treated with NaOH,and that the shear strength and bend strength of ramie fiber reinforced cellulose acetate composites are modified.
