The invention refers to the configuration of a tip structure (1) for an aircraft airfoil, such as a control surface (ailerons, flaps, elevators, rudders, etc) and/or a lifting surface (wings, HTP's, VTP's). The tip structure (1) is a unitary body and comprises a tip shell (2) and a metallic material on the outer surface of the tip shell (2) suitable to withstand a lighting strike, wherein the tip shell (2) has been obtained by a single-stage injection molding process using a thermoplastic composite material having fibers dispersed therein, and wherein the metallic material has been integrally formed with the tip shell (2). The invention provides a tip configuration that can be manufactured in one-shot process, fulfilling structural, operational and aerodynamic requirements and achieving thereby high production rates and reducing manufacturing costs.
