Impactor Diameter and Ply Number Effects on the Impact Behavior of Carbon Fiber Composite Laminates

As it is known, impact damage a major mechanical phenomena for composite materials especially used in the aerospace structures. The factors affecting behaviour of composites depend on impactor systems as well target material. In this study ply number and geometry effects carbon fiber reinforced epoxy were investigated by tests. context, drop weight tests carried out at 6J, 12J 24J energy levels using hemispherical impactors with 10 mm 20 diameters. Laminated manufactured 6, 14 plies vacuum infusion method. laminate thickness, diameter force, velocity, absorbed surfaces investigated. It observed that geometries velocities caused different mechanisms played an important role determining penetration perforation behaviours composites.
