Sustainable Development of Agro-Industrial Waste-Based Banana Fiber/Fly Ash Polyester Composites for Wear and Friction Study

ABSTRACT

The present work aims to investigate the wear and friction characteristics of banana fiber (BA)/fly ash (FA) reinforced polyester composites fabricated using manual hand layup technique. Wear analysis was carried out with control parameters of filler content 1, 3, and 5 vol.%, speed 300, 500, and 700 rpm, load 20, 40, and 60 N, and time 5, 10, and 15 min to obtain minimum wear responses. Taguchi analysis shows that minimum wear rate was obtained at control parameters of 20 N load, 700 rpm speed and 15 min time on composites with 1, 3, and 5 vol.% of fly ash. ANOVA analysis depicted that the load was the most significant factor which induced a wear rate of 17.70 and coefficient of friction (COF) 22.56 on the F-value compared to other factors. The combined effect of the filler content and the sliding speed is most significant with an F value of 4.29 on the wear rate and 3.44 on the coefficient of friction when compared to other interactions. Material removal mechanisms from worn-out surfaces were identified using SEM characterization. These types of composites can be considered for low load applications such as interior parts of automobiles, interior architecture products, electronic panels, etc.

摘要

本研究旨在研究手动铺层技术制备的香蕉纤维 (BA)/粉煤灰 (FA) 增强聚酯复合材料的磨损和摩擦特性. 使用填料含量1、3和5 vol.%、转速300、500和700rpm、载荷20、40和60N以及时间5、10和15 min的控制参数进行磨损分析, 以获得最小磨损响应. 田口分析表明, 在控制参数为20 N负载、700rpm转速和15 min时间时, 含1、3和5 vol.%飞灰的复合材料的磨损率最小. 方差分析表明, 与其他因素相比, 载荷是导致F值磨损率为17.70, 摩擦系数 (COF) 为22.56的最显著因素. 与其他相互作用相比, 填料含量和滑动速度的综合影响最为显著, F值对磨损率的影响为4.29, 对摩擦系数的影响为3.44. 使用SEM表征确定了磨损表面的材料去除机制. 这些类型的复合材料可用于低负荷应用, 如汽车内部零件、内部建筑产品和电子面板等.
