摘要

在将天然纤维用于复合材料增强材料之前，必须克服与天然纤维相关的问题。天然纤维最受关注的是
其亲水性。此外，该试剂用于处理天然纤维的大部分用途是：昂贵、危险和降低处理后纤维的强度。使用蛋壳
粉溶液处理天然纤维的环保试剂的开发是本次调查的信任。这项工作中使用的天然纤维是香蕉花梗纤维。纤维
用 （NaOH） 预处理并用蛋壳 （ES） 粉末溶液处理。测定显微组织、拉伸强度和吸水率。预处理纤维的最大强度
（99.844N/mm2
） 在 0.25M NaOH 浓度下达到 1 小时。 ES 处理使吸水率显着降低至 2.6%，与原纤维（35.83%）相
比提高了 91.6%，并且没有苛刻和危险。根据本研究中获得的结果，建议在水中 20% ES 的 ES 处理可用于处理用
于复合材料生产的天然纤维。
