Composite materials are widely used in aircraft due to their high specific strength and stiffness, superior impact resistance, and excellent fatigue performance. Bird strikes can inflict severe damage to critical aircraft components such as the fuselage, engines, and wings, thereby compromising flight safety. Aircraft certification regulations require that all components demonstrate a specified level of bird strike resistance before aircraft installation. Given these requirements, this study focused on the use of carbon fiber composite laminates in aircraft components. By varying impact velocity, impact angle, and ply orientation, the study investigated the resulting patterns of bird-strike impact behavior in composite materials. The derived patterns provide a theoretical reference for further research into the impact mechanics of composite materials subjected to bird strikes.
