The growing demand for lightweight, fuel-efficient, and structurally reliable aircraft has accelerated the
use of advanced materials in wing construction. This study presents a comparative static and fatigue
analysis of aircraft wing structures fabricated using Aluminum 7075-T6, Carbon Fiber Reinforced
Polymer (CFRP), and Glass Fiber Reinforced Polymer (GFRP). A unified 3D wing model was developed
and analyzed under identical aerodynamic loading using Finite Element Method (FEM) simulations.
The results show that CFRP exhibits the highest stiffness with the lowest deformation (12.7 mm),
reduced stress response (189 MPa), and exceptional fatigue endurance exceeding one million cycles.
Aluminum 7075-T6 demonstrates moderate structural performance, while GFRP shows the highest
deformation and the shortest fatigue life. These findings highlight CFRP as the most efficient material
for modern aircraft wings, offering significant improvements in structural stability, fatigue resistance,
and weight reduction. The study provides valuable insights for material selection aimed at optimizing
aircraft performance, durability, and fuel economy.
