Dynamic Characterization of Injection Molded Short Fiber Reinforced Polymer

Abstract: This study investigates the dynamic characterization of injection-molded short fiber-reinforced polymers, with a specific focus on enhancing the mechanical properties of Acrylonitrile Butadiene Styrene (ABS) through the incorporation of glass fiber, carbon fiber, and Kevlar fiber. The project commenced with the design and manufacturing of a specialized injection mold, followed by the production of various composite samples. These samples were prepared with different fractions of each fiber type to evaluate their influence on the material’s performance, particularly in the context of lightweight, high-strength materials suitable for sustainable transportation. The core objective was to conduct a comprehensive analysis of the impact strength and tensile strength of these fiber-reinforced ABS composites, with an emphasis on their potential use in automotive and aerospace applications. Additionally, the research explored the effects of hybridization, wherein combinations of two and three different short fibers were integrated into the ABS matrix. Notably, certain hybrid configurations demonstrated remarkable improvements in both impact strength and tensile strength compared to single-fiber reinforcements. The results underscore the potential of fiber hybridization as a strategy for optimizing the mechanical properties of polymer composites, contributing to the development of lighter, stronger, and more energy-efficient materials for sustainable transportation. This study highlights the role of advanced composites in reducing vehicle weight, improving fuel efficiency, and minimizing the environmental impact of the transportation sector.
