Abstract

The oblique impact damage model of hybrid fiber metal laminates is established, and the process of the bullet impacting aluminum alloy-carbon/glass hybrid fiber laminates with multi-angle and high speed is numerically simulated to explore the influence of impact angle on energy absorption, contact force and interlayer failure area of metal fiber laminates. The results show that the kinetic energy consumption decrease with the increase of the impact angle. The impact angle directly affects the energy absorption characteristics of the hybrid fiber metal laminate. As a whole, the failure area of metal layer and fiber layer decreases with the impact angle. The failure area of the carbon fiber layer is smaller than that of the glass fiber layer, and the failure area of the glass fiber layer from the top to the bottom gradually increases, but the failure area of the carbon fiber layer from the top to the bottom has no obvious change. Because of the impact angle, the kinetic energy dissipation, the maximum fiber stress position and failure area of hybrid fiber metal laminates have significant effects.
