This document summarizes research conducted on modeling and stress analysis of composite materials for spur gears under static loading conditions. A spur gear model was created in SolidWorks and analyzed using six different materials: stainless steel, malleable cast iron, 6061 alloy, S-glass epoxy composite, CFRP, and E-glass epoxy composite. The SolidWorks simulation tool was used to analyze von Mises stresses and displacement. Results showed the S-glass epoxy composite experienced the lowest von Mises stress of 3.105MPa and low displacement, indicating it is the best material for withstanding static loads in spur gears.
