This paper presents a systematic approach to designing spur gears with composite materials, offering advantages in strength, weight, and durability. Material selection considers properties like strength, stiffness, wear, fatigue resistance, and temperature stability. Geometry design adheres to standard principles, with modifications to minimize stress concentrations. Finite element analysis identifies weaknesses and aids iterative optimization. Manufacturing techniques, such as layup and filament winding, are chosen based on fiber orientation and bonding considerations. Prototypes undergo rigorous testing for mechanical performance, fatigue, and wear. Documentation ensures compliance with industry standards. This approach promises lightweight, high-performance gear solutions for various engineering applications.
