The axial compressor considers the main component and plays a significant role in highspeed engines and it is subjected to different loads during the operations conditions. In this work, the simulation of the mechanical performance of the axial compressor under various loads was achieved. The simulation of the axial compressor (semi-open impeller type) was achieved with SOLIDWORKS 2016 while the structural numerical analysis was performed with ANSYS 2020 with three different materials which were (stainless steel, titanium, carbon fiber) to study the effect of different force values (5000, 10000, 15000) N on the mechanical performance of the axial compressor and to compare the behavior of modern material such as carbon fiber, which has been recently in the manufacturing of mechanical parts due to its significant properties like a high strengthweight ratio, with the other traditional materials. The output results were directional deformation, overall deformation, highest stress, highest shear stress and maximum strain. The results revealed that the carbon fiber showed the highest deformation more than the other two materials because of the type of failure that happened under loads such as delamination and cracks which may cause sudden failure for the compressor.
