Effect of Fibre Parameters on the Physical and Mechanical Properties of Epoxy-Based Reinforced Deleb Palm Fibre Composite; Using Taguchi Grey Relational Optimization

This study considered the consequence of the length and weight composition percentage of Deleb palm fruit fiber on the physio-mechanical characteristics of an epoxy-based composite through the Taguchi grey relational optimization technique. Considering fiber reinforcement of 30 wt% to 40 wt% and fiber Reinforcement Length (RL) of 1-5 mm, the physical and mechanical properties were determined based on standards. The findings demonstrated that the Deleb palm fruit fiber’s characteristics tend to differ from those of other types of fiber reinforcement in that they significantly impact the physio-mechanical characteristics of the resulting epoxy-based reinforced Deleb palm fruit fiber composite. The  Analysis of Variance (ANOVA) result showed that, at a confidence interval of 5%, the effects of the fiber characteristics on the physio-mechanical properties of the composites were particularly notable for tensile strength and a decrease in water absorption.
