Experimental study on bio fiber reinforced composites

Abstract

Biofibers are an economical, environmentally friendly, and lightweight alternative to traditional materials. Different types of fibers have different properties, and each plays a key role in composites. Screw Pine (Pandanus Odoratissimus) is abundant and strong. This research made and tested NaOH- and Acetic Acid-treated random fiber composites. This research shows the mechanical properties of Pandanus Odoratissimus composite. The stem of the screw pine plant, Pandanus Odoratissimus, contained several interesting fibers (PO fibers). This research will investigate the effect of fibre concentration and alkali treatments on the mechanical properties of unsaturated polyester matrix composites. Similarly, soaking times will vary for alkali treatments. Individual PO fibres exhibit modifications in their cross-sectional area and water absorption prior to and after treatment with NaOH solution and acetic acid for varying durations of time. These modifications are observable prior to and after treatment. As a result of extended therapy, the cross-sectional area of PO fibres gradually decreases. Compared to other fibre types, PO fibres that were submerged in water for the longest period of time exhibited the most structural degradation. There is a considerable effect on the improvement of polyester composites' tensile strength and tensile modulus when PO fibre is soaked in different concentrations of NaOH and acetic acid for roughly 90 min. This influence is significant. This investigation will also shed light on how the composition of polyolefin (PO) fibres influences the mechanical properties of composite materials. Maximum tensile strength of a composite material is proportional to the fraction of fibres present in the material. After calculating tensile, compressive, shear, and other stresses, materials (components) are manufactured.
