ABSTRACT Jute fabrics reinforced low-density polyethylene (Jute/LDPE)-based composites were prepared by compression molding technique. Jute fabrics were treated with disaccharide. The fiber content of the composites was kept constant (40% by wet). For the optimization of sucrose quantity, 0.5%, 1.0%, 2.0%, 5.0%, and 10.0% solution were prepared. For 2.0% sucrose solution, the Jute/LDPE-based composite showed the best result and the tensile strength (TS), tensile modulus (TM) and elongation at break (Eb) were 26, 940 MPa, and 18% respectively. The TS, TM and Eb values of the sucrose-treated jute/LDPE composite were low at 1% sucrose solution and the highest at 2% sucrose solution then the values decreased linearly with the increment of sucrose percentages. For 2% solution TS, TM and Eb were increased 10%, 50%, and 47% respectively with respect to non-treated composites. The impact strength(IS) was also improved about 16% with the addition of 2% sucrose. When gamma radiation (2.5, 5.0, and 7.5 KGy) was passed through the composites, the sucrose-treated composites showed relatively lower mechanical properties than the untreated composites. At 5.0 KGy gamma dose, both composites showed the best result. The water uptake property of the sucrose-treated composites was comparatively high. SEM and FT-IR were observed for both composites.

黄麻纤维增强 LDPE 基复合材料的物理机械性能：二糖（蔗糖）和伽马辐射的影响

摘要黄麻织物增强低密度聚乙烯（黄麻/ LDPE）基复合材料通过压缩成型技术制备。黄麻织物用二糖处理。复合材料的纤维含量保持恒定（40% 湿）。为了优化蔗糖量，分别制备了 0.5%、1.0%、2.0%、5.0% 和 10.0% 的溶液。对于 2.0% 蔗糖溶液，黄麻/LDPE 基复合材料表现出最好的结果，拉伸强度 (TS)、拉伸模量 (TM) 和断裂伸长率 (Eb) 分别为 26、940 MPa 和 18%。蔗糖处理的黄麻/LDPE复合材料的TS、TM和Eb值在1%蔗糖溶液中较低，在2%蔗糖溶液中最高，然后随着蔗糖百分比的增加而线性下降。对于 2% 溶液 TS、TM 和 Eb 分别增加 10%、50%、和未经处理的复合材料分别为 47%。添加 2% 蔗糖后，冲击强度 (IS) 也提高了约 16%。当伽马辐射（2.5、5.0 和 7.5 KGy）通过复合材料时，经蔗糖处理的复合材料显示出比未经处理的复合材料相对较低的机械性能。在 5.0 KGy γ 剂量下，两种复合材料都显示出最好的结果。蔗糖处理复合材料的吸水性能较高。对两种复合材料都进行了 SEM 和 FT-IR 观察。两种复合材料都显示出最好的结果。蔗糖处理复合材料的吸水性能较高。对两种复合材料均进行了 SEM 和 FT-IR 观察。两种复合材料都显示出最好的结果。蔗糖处理的复合材料的吸水性能较高。对两种复合材料都进行了 SEM 和 FT-IR 观察。
