In this study, with their high strength-to-weight ratio, adaptability, and lack of corrosion, composite materials are widely used in aircraft construction and can be considered an acceptable metal substitute by all parties involved. Static load tests have been performed under identical conditions and stresses, but the layer sequence was changed. The Ansys workbench ACP-pre is utilized to analyze the data. Various deformations were found as a result of this. There are values of 14.265 and 0.1335 for the smallest z-direction deformation and for the overall strain in the composite 3 examples. Boundary conditions have been confirmed with 1,500 N as a resultant force with the static condition. The simulation results have been analyzed as a static condition. Four materials have been employed in different order to be investigated and these materials are Sisal, Pineapple, Jute, and Kenaf. The numerical results have been undertaken using the static structure of Ansys 16.1 Version tool. Geometry has been modeled and meshed using Ansys workbench. The model has been verified using convergence test. As the output, total deformation and von Mises stresses were investigated and explained accordingly. Numerical results stated that the maximum deformation due applied load was at the Z-axis. The maximum total deformation value is 1.254 mm and the minimum is 2.5 mm. Furthermore, von Mises stresses of the entire body have been calculated. The numerical results have shown the maximum result due to 1,500 N is 1.1 mPa. Eventually, the main aim has been achieved by employing total deformation and von Mises stresses accordingly
