Abstract

Plastic, a versatile synthetic polymer, holds considerable significance and utility in human society due to its manifold applications. However, its deleterious ecological ramifications have spurred growing apprehensions. This has galvanized the pursuit of ecologically amicable substitutes, propelling interest in the domain of composite materials. Composites are formulated by amalgamating diverse substances, and in this context, Styrene Diluted Unsaturated Polyester Resin (SDUPR) is melded with natural constituents. Among these organic constituents, Sorghum Husk is the subject of scrutiny in this inquiry. The formulation of these composites entails a multiplicity of methodologies, encompassing Spray-Up, Pultrusion, Manual Layup, Automated Layup, and Resin Transfer Molding. In this specific examination, the manual layup technique is harnessed. The procedure encompasses the fabrication of sheets with varying proportions of Sorghum Husk and SDUPR, concomitant with the inclusion of a curing agent to expedite solidification. In this study, four distinct composite sheets are engendered, distinguished by Sorghum Husk to SDUPR ratios of 50:50, 55:45, 60:40, and 65:35. The performance appraisal of these composite sheets is effectuated through a battery of evaluations. These encompass the Flexural Test, quantifying material flexural potency; the Izod Impact Test, assessing material tenacity; the Rockwell Hardness Test, appraising material resistance to indentation; and the Biodegradability Test, measuring the material’s intrinsic degradation process. Hardness and biodegradability profiles evince fluctuations in tandem with the manipulation of Sorghum Husk and SDUPR ratios. Comparative scrutiny among the four sheets accentuates the mechanical property modulations as the equilibrium between Sorghum Husk and SDUPR is transmuted. The revelations evince that an upswing in Sorghum Husk concentration begets a decrement in mechanical attributes such as pliancy, hardness, and impact resilience. Additionally, the biodegradability of the composite substrate dwindles with augmented Sorghum Husk proportions. Fundamentally, this inquiry elucidates the intricate interplay between Sorghum Husk and SDUPR ratios and the ensuing composite material traits. The findings underscore the inherent compromises in optimizing both mechanical efficiency and environmental imprint, furnishing invaluable insights into the evolution of sustainable composite materials.

Keywords: Biodegradability, composites, hardness, sorghum husk, polyester resin.
