The pursuit of sustainable and renewable energy sources has led to significant advancements in wind energy technologies. Windmills play a pivotal role in harnessing wind energy for power generation. One critical aspect of windmill design is the optimization of components to enhance efficiency, durability, and overall performance. In this study, the focus is on the weight optimization of the windmill shaft through the utilization of composite materials, aided by Finite Element Analysis (FEA) techniques. This contribution deals with the simulation of Shaft made up of complex part (i.e. composite materials). There is need of low density and high Tensile strength of any shaft which will increase it’s working efficiency and reduce weight. Initially the existing shaft is solid then converted into hollow and finally composited of same diameter. These all three are tested under FEA and results are compared with each other for better one. The composite layered (Glass Fibre or Carbon Fibre which ever is the best from both) trying with different Fibre Orientations on outer diameter of shaft. The different fibre angle gives different effect to the shear stress Von-mises stresses and deformations. The results are compared from numerical analysis and we get the better fibre angle for good strength shaft. In this way wind mill shaft get optimized by getting good results of composite shaft by comparison with existing.
