ABSTRACT

Surface modification of a jute fibrous reinforcement is preferred to improve its compatibility with thermosetting resin for the development of biocomposite. A plain weave jute fabric was chemically modified with different concentrations of sodium hydroxide (NaOH) i.e. 1 to 6% (weight/volume). The chemically modified jute fabrics were assessed for their physical, mechanical, and morphological properties. The modified jute reinforcements were used for the preparation of biocomposite by hand laying method cum compression molding method, and the respective biocomposites were evaluated for their physical and mechanical properties. Results inferred that NaOH modified the fine structure and morphological properties of treatment on jute reinforcement and the reinforcing ability of the modified jute fabric is increased with increasing in the concentration of NaOH up to 5% (w/v) and then stabilized. It is concluded that the suitable concentration for improved reinforcement is found at 5% (w/v) at 30°C for 60 min in 1:15 material-to-liquor ratio.

摘要

黄麻纤维增强材料的表面改性是首选，以提高其与热固性树脂的相容性，以开发生物复合材料。用不同浓度的氢氧化钠 (NaOH) 对平纹黄麻织物进行化学改性，即 1 至 6%（重量/体积）。对化学改性黄麻织物的物理、机械和形态特性进行了评估。将改性黄麻增强材料通过手工铺设法和压塑法制备生物复合材料，并对各自的生物复合材料进行物理和力学性能评价。结果推断，NaOH对黄麻加固处理的精细结构和形态性能进行了改性，并且改性黄麻织物的加固能力随着NaOH浓度的增加而增加至5％（w / v），然后稳定下来。得出的结论是，在 30°C 下以 1:15 的料液比保持 60 分钟 5% (w/v) 时，发现改善增强效果的合适浓度。
