ABSTRACT
In this experimental work, the influence of Haritaki (Terminalia chebula) powder on thermo-mechanical, water absorption, and morphological properties of Tindora (Coccinia grandis) tendrils fiber-reinforced epoxy composites is investigated. The Coccinia grandis fibers (CGFs) were extracted from tendrils of the Tindora plant, and composites with and without Haritaki powder (HP) are fabricated by using hand layup and compression molding techniques. The mechanical strengths, water absorption studies, and the characterization techniques such as thermogravimetric analysis, differential scanning calorimetry, X-ray diffraction studies, Fourier transform infrared spectroscopy, and scanning electron microscopy studies are conducted. From the results, it is found that the mechanical strengths of the HP filled C. grandis fiber-reinforced composites (HPCGFRCs) are 14.26–26.59% higher than that of those without HP composites. The maximum weight gain percentages of CGFs and their composites due to water absorption varied between 6.32% and 10.63%. Findings of the experiments reveal that the inclusion of HP has a significant influence on the properties of CGFRCs and ascertained that HP could be the potential nanofiller formost of the polymer matrix composites.
摘要
研究了诃子粉对大球虫卷须纤维增强环氧树脂复合材料的热机械性能、吸水性能和形态结构的影响。采用手糊法和模压法，从丁多拉植物的卷须中提取了巨球虫纤维（CGFs），制备了含和不含Haritaki粉（HP）的复合材料。进行了机械强度、吸水性研究和表征技术，如热重分析（TGA）、差示扫描量热法（DSC）、X射线衍射（XRD）、傅立叶变换红外光谱（FTIR）和扫描电子显微镜（SEM）研究。结果表明，HP填充的巨球菌纤维增强复合材料（HPCGFRCs）的力学强度比未填充HP的复合材料高14.26%～26.59%。CGFs及其复合材料的最大吸水增重率为6.32%～10.63%。实验结果表明，HP的加入对巨球菌纤维增强复合材料（CGFRCs）的性能有显著影响，HP有望成为大多数聚合物基复合材料的潜在纳米填料.
