Abstract – As one of the growing energy storage
result, there has been a growing interest in composite materials to design and optimize flywheels for enhanced performance. Composite flywheels, owing to their high strength-to-weight ratio and fatigue resistance, allow for higher rotational speeds, which directly translate into increased energy storage capacity. Furthermore, the ability to customize material properties of composites offers new avenues for reducing system weight while maintaining or even improving the overall mechanical integrity and efficiency.
technologies that are currently accessible in various stages of development, particularly in advanced technological fields, flywheels function as kinetic energy storage and retrieval devices with the capacity to deliver high output power at high rotational speeds., i.e., spaceships. Three main criteria determine a flywheel's performance: rotating speed, crosssectional shape, and material strength. The kinetic energy level that may be produced safely when linked with rotor speed is directly determined by material strength; however, the focus of this study is only on investigating how flywheel material affects the energy storage and delivery capacity per unit mass, also known as specific energy. The findings of a proposed computer-aided analysis and optimization technique demonstrate that choosing the right flywheel material could significantly impact the Specific Energy performance and lessen the operational pressures placed on the shaft and bearings at high rotational speeds because of the reduced mass. Three rim type flywheels are designed on Solidworks software and structural analysis is done on Ansys software. The first flywheel is made up of mild steel and for reducing its weight composite flywheel is also developed. Carbon fiber is used for making other two flywheel. Out of three the flywheel made-up of carbon fiber body and mild steel rim will be more efficient and lighter in weight.
Despite these advantages, the design and analysis of composite flywheels present significant challenges. Factors such as material anisotropy, dynamic stress distribution, and failure modes must be carefully considered. This research focuses on the design, analysis, and optimization of composite flywheels to maximize efficiency and energy storage capability. Through finite element modelling, material selection strategies, and stress analysis, the study aims to contribute to the growing body of knowledge on composite flywheel systems, addressing the critical need for efficient energy storage technologies in modern applications.
2. PROBLEM STATEMENT In the quest for efficient energy storage solutions, traditional flywheels made from metallic materials, such as steel, are hindered by their high weight and limited rotational speed. While metallic flywheels offer good strength, their significant mass limits the energy storage capacity per unit weight, making them less suitable for applications requiring high energy density, such as electric vehicles and renewable energy systems.

1.INTRODUCTION In today's fast evolving technological era, the need for efficient, sustainable, and high-performance systems is driving innovations in various engineering domains. Among these, energy storage solutions play a pivotal role, particularly as the world moves towards renewable energy integration and electric mobility. One such promising technology is the flywheel energy storage system (FESS), which offers the ability to store kinetic energy in a rotating mass, providing high power density, life fast chargedischarge capabilities, and long cycle.
The need for lightweight, high-strength materials has led to the exploration of composite flywheels, which offer the potential to operate at higher speeds, thereby increasing energy storage efficiency. Composite materials, particularly carbon fiber, exhibit excellent strength-to-weight ratios, which enable flywheels to achieve higher rotational speeds with reduced mass. However, the optimization of composite flywheels presents several challenges, including managing stress distribution, preventing delamination, and ensuring long-term durability under cyclic loading conditions.
Conventional flywheels, typically made from steel or other metals, face limitations in terms of energy density and rotational speeds due to their material properties. As a
