Abstract

In this study, the effect of alkali treatment on the tensile strength of the hibiscus fiber, gongura fiber, and treated madar fiber-reinforced Polymer Matrix Composite (PMC) is studied. The Sodium Hydroxide (NaOH) solution is utilized for madar fiber treatment. The traditional hand layup methodology was used for fabrication. The influence of tensile property control variables such as duration of fiber treatment, concentration of NaOH for treatment, and proportion of fiber hybridization on the tensile strength is examined. Taguchi’s Signal to Noise Ratio (SNR) and Analysis of Variance (ANOVA) are used to find the optimum control variables and percentage contribution of control variables on the tensile strength, respectively. The 24 hours of fiber treatment, 15% concentration of NaOH, and 70% fiber hybridization were found to be the optimum control variables. Moreover, the duration of fiber treatment contributed more to the tensile behaviour of the PMC. The prolonged treatment durations can enhance the removal of contaminants, waxes, and non-cellulosic compounds. This process strengthens the matrix-fiber interaction, thereby raising the tensile strength. Finally, the Scanning Electron Microscope (SEM) is used to examine the surface of the best tensile sample, and it showed signs of fiber pullout, fiber splitting, debonding, matrix cracking, and fiber-matrix interaction.

Keywords: Natural fiber, polymer matrix composite, alkali treatment, tensile strength, matrix-fiber interaction
