Two varieties of jute fiber, tossa (Corchorus olitorius) and white (Corchorus capsularis), were combined with nano-clay (montmorillonite clay) modified polyester to fabricate composites using the hand lay-up method. The goal was to examine the impact of nano-clay on structural, mechanical, and thermal properties. The two types of jute fibers were first treated with NaOH, and the polyester was then modified with montmorillonite nanoclay (1, 2, 3) (wt%). Finally, 30 cm long unidirectional fibers were used to fabricate a composite (fiber volume fraction is 19.3%). Accordingly, the structural (crystallinity), mechanical, and thermal properties of the composite were examined using the XRD, UTM, and TGA apparatus. Regarding crystallinity, treating the tossa jute fiber and its composite with nano-clay demonstrated improved crystallinity indices of 75.24% and 75.52%. The Tossa jute fiber composite treated with 1% nano-clay exhibits an increased tensile strength of 97.8805 MPa, which is 10.92% higher than the treated fiber without NC, and a flexural strength of 159.79 MPa, which is 3.12% higher than the treated fiber without NC). In comparison to white jute composite, the treated tossa jute fiber composite showed improved thermal stability; the addition of 3% nano-clay also demonstrated higher thermal stability. The use of modified polyester in composites along with nano-clay produces better outcomes in every way. [ABSTRACT FROM AUTHOR]
将两种黄麻纤维 tossa (Corchore olitorius) 和白色 (Corchores capsularis) 与纳米粘土 (蒙脱石粘土) 改性聚酯结合, 采用手工铺层法制造复 合材料. 目的是研究纳米粘土对结构、机械和热财产的影响. 两种类型的黄 麻纤维首先用 NaOH 处理, 然后用蒙脱土纳米粘土 (1, 2, 3) (wt%) 对聚 酯进行改性。最后, 使用30 cm长的单向纤维制造复合材料 (纤维体积分数 为19.3%). 据此, 使用 XRD、UTM 和 TGA 仪器检查了复合材料的结构 (结晶 度)、机械和热财产. 关于结晶度, 经处理的黄麻纤维及其与纳米粘土的复 合材料的结晶度指数提高了 75.24% 和 75.52%. 用 1% 纳米粘土处理的Tossa 黄麻纤维复合材料的拉伸强度增加了 97.8805MPa, 比未经 NC 处理的纤维高 10.92%, 弯曲强度增加了 159.79MPa, 比未经过 NC 处理的光纤高 3.12%). 与 白黄麻复合材料相比, 经处理的 tossa 黄麻纤维复合材料表现出更好的热稳 定性; 3%纳米粘土的加入也显示出较高的热稳定性. 在复合材料中使用改 性聚酯和纳米粘土在各个方面都能产生更好的效果.
