Effect of Process Parameters on the Fabrication of Hybrid Natural Fiber Composites Fabricated via Compression Moulding Process

ABSTRACT

In the present work, an attempt has been made to fabricate hybrid natural fiber composites, consisting of a poly-lactic-acid (PLA) matrix reinforced with jute and sisal fibers, using die molding process. The processing conditions of the hybrid composites, such as heating temperature, compression pressure, and final mold temperature, have been optimized in the response of the resulting tensile and flexural strength. The reinforced hybrid composites have been developed in accordance with the Taguchi L9-based design of experimentation, and statistical analysis has been performed to understand the significance of the selected input parameters. Furthermore, scanning electron microscopic (SEM) analysis of the fractured samples has been performed to observe the mechanisms of failure and adhesive characteristics. The statistical analysis highlighted that all input process parameters have significantly contributed to the resulting tensile and flexural strength at 95% confidence level.

摘要

在目前的工作中, 已经尝试使用模塑工艺制造混合天然纤维复合材料, 包括用黄麻和剑麻纤维增强的聚乳酸 (PLA) 基体. 混杂复合材料的加工条件, 如加热温度, 压缩压力和最终模具温度, 已根据产生的拉伸和弯曲强度进行了优化. 根据基于田口L9的实验设计开发了增强混杂复合材料, 并进行了统计分析, 以了解所选输入参数的重要性. 此外, 还对断裂样品进行了扫描电子显微镜 (SEM) 分析, 以观察失效机理和粘合特性. 统计分析强调, 在95%置信水平下, 所有输入工艺参数对产生的拉伸和弯曲强度有显著影响.
