Exploring Natural Frequency and Damping in Coir-Rubber Polymer Composites for Vibration Control in Mobility Vehicles

This study delves into the dynamic properties of hybrid composite materials, specifically focusing on the natural frequency and modal damping characteristics of Coir Fiber-Rubber Particles Reinforced Polymer Composites (CRP). Comprehensive experimental investigations were conducted utilizing an FFT analyzer. Initial experiments involved the preparation of specimens with varying rubber content, ranging from 2% to 5%. Coir, known for its cellulose-rich composition, was selected due to its innate damping properties, making it highly effective in mitigating vibrations. The primary motivation behind this research is to provide cost-effective solutions for reducing vibrations in mobility vehicles, addressing challenges associated with passenger comfort, durability, and overall performance. The study yielded promising results, with CRP exhibiting substantial reductions in vibrations. The findings of this research are expected to serve as valuable inputs for the design and engineering of components utilizing these novel composite materials. By characterizing the natural frequencies and damping properties, this study empowers engineers and designers with crucial insights for selecting appropriate materials to tackle vibration-related challenges in mobility vehicle applications.
