Effectiveness of Rattan Fiber as a Reinforcing Material in Polymer Matrix Composites: An Experimental Study

, , , , , & show all
 

ABSTRACT

It has been proposed that rattan fiber (RA) as reinforcement can be a promising candidate for the fabrication of composites. In present research, composites were fabricated by reinforcing rattan fibers with poly(vinyl) alcohol (PVA) matrix. Its various properties (mechanical, thermal, and morphological properties) were evaluated and compared with that with neat PVA. Surface treatments of fibers were carried out to have a better compatibility with PVA matrix. The mechanical properties were found to increase at the early stage with the increase in treated rattan fiber content till optimum (24 wt%) fiber loading and thereafter declines. At 24 wt% (optimum) fiber loading the mechanical properties obtained were 48.722 MPa of tensile strength, 45.72 MPa of flexural strength, 1.57 GPa of young’s modulus and 5.89 kJ/m2 of impact strength. Thermogravimetric analysis (TGA), dynamic mechanical analysis (DMA), and scanning electron microscopy (SEM) were used for analysis. The TGA inferred that the thermal stability of the composites increased as compared to neat PVA matrix. It was found that composites fabricated from 24 wt% fiber content shows superior mechanical properties as well as thermal properties as compared with other fabricated composites and can be used for making partition boards, light weight packaging boxes, and furniture.

摘要

藤纤维(RA)作为增强体是制备复合材料的一种很有前途的材料. 采用聚乙烯醇(PVA)增强藤条纤维制备复合材料. 对其各项性能(力学性能、热性能和形态性能)进行了评价,并与纯PVA进行了比较. 对纤维进行表面处理,使其与PVA基体具有较好的相容性. 结果表明,随着处理后藤条纤维含量的增加,其早期力学性能逐渐提高,直至纤维含量达到最佳值(24wt%),然后逐渐下降. 当纤维质量分数为24wt%(最佳)时,拉伸强度为48.722mpa,弯曲强度为45.72mpa,杨氏模量为1.57gpa,冲击强度为5.89kj/m2。采用热重分析(TGA)、动态力学分析(DMA)和扫描电镜(SEM)进行分析. 热重分析表明,与纯PVA基体相比,复合材料的热稳定性有所提高. 结果表明,与其它复合材料相比,纤维含量为24%的复合材料具有优异的力学性能和热性能,可用于制造隔墙板、轻质包装箱和家具.
