Abstract

High density polyethylene composite reinforced with natural plantain fiber was produced using injection moulding technique. The production process utilized the popular L18 Taguchi experimental design to investigate the effects of the major process variables such as barrel temperature, mold temperature, injection pressure, holding pressure, back pressure, clamping force and shaft speed in the final mechanical property of the composite material. The mechanical tests conducted on the new material reveal that fiber volume fraction of 0.1 combined with particle size of 75 μm and compactibilizer mass of 0.00024 kg gives a high-quality composite material suitable for auto body fender application, at reduced manufacturing cost of ₦1454/kg of the composite. The composite material produced at optimized process condition was found to have tensile strength of 87.44 MPa, yield strength of 76.6 MPa, flexural strength of 77.03 J, Rockwell hardness strength of 756.99, Impact strength of 16.21 J and density of 993 kg/m3. The result shows that the auto body fender produced based on the compactibilized plantain fiber reinforced high-density polyethylene composite has an advantage of low density and reduced production cost compared to conventional/alternative materials.

Abstract

Lately, there has been a growing global awareness about the negative impact of synthetic fibres and the need for replacement with eco-friendly, plant-based natural fibres. However, the hydrophilic nature of these natural fibres can create compatibility issues with various matrices, which limits their use. This has sparked an increased research interest in finding an effective mercerization process to modify the surface of these plant-based fibres, ultimately enhancing their mechanical properties. In this study, fruit fibres from the Pentaclethra macrophylla plant was processed, experimented with NaOH soaking times of 1 hour, 3 hours, and 5 hours, along with treatment concentrations of 2%, 5%, and 8% by weight. The tensile properties of the composite made from these processed fibres were examined, and statistical analysis using one-way analysis of variance (ANOVA) and regression in Minitab software was conducted. The results showed a 21% decrease in tensile strength and a 32% increase in elastic modulus as the soaking time increased from 1 hour to 5 hours. Additionally, increasing the NaOH treatment concentration from 2% to 8% led to enhancements in both tensile strength and elastic modulus. This study shows that the tensile properties of the fiber composite are greatly impacted by both the soaking time and NaOH concentration. Therefore, optimising the parameters of the mercerisation process can enhance these properties, making the Pentaclethra M. fibre-reinforced composite a viable option for automotive applications.
