Optimization Studies on Improving the Dielectric Properties of Alkali Treated Fibers from Phaseolus Vulgaris Reinforced Polyester Composites by Central Composite Design

ABSTRACT

This study investigates the dielectric efficiency of a composite prepared using a fiber extracted from Phaseolus vulgaris. The extraction of fiber was statistically modeled using face-centered central composite design. The concentration of NaOH and extraction time was taken as the process variables and dielectric strength was taken as the response. The numerically optimized model for the extraction of fiber from Phaseolus vulgaris of alkali treatment showed 14.325 kV/cm as dielectric strength of initial NaOH concentration of 3% and time period of 51 min. The model was significant with R² = 0.9323 and adjusted R^{2 =} 0.884. The linear, quadratic & interactive relationship between the response (dielectric strength) and variables (NaOH & time) was also established. This study explains the importance of NaOH and time period in establishing the fiber extraction by the alkali treatment process.

摘要

本研究研究使用从西多卢斯提取的纤维制备的复合材料的电介质效率. 纤维的提取采用以面为中心的中央复合设计进行统计建模. 以NaOH的浓度和提取时间作为过程变量和介电强度作为响应. 碱处理的Phaseolus纯化纤维提取数值优化模型显示，初始NaOH浓度为3%，周期为51分钟，介电强度为14.325千伏/厘米. 该模型在 R2 = 0.9323 和调整后的 R2 = 0.884 时显著. 建立了响应（电强度）和变量（NaOH + time）之间的线性、二次和交互关系. 本研究阐述了NaOH和时间段在碱处理工艺建立纤维提取过程中的重要性.
