Abstract
A method for forming a structural component for an airframe of an aircraft or spacecraft, includes: providing a prefabricated shell element comprising a thermoplastic substrate; and applying a stiffening structure to the shell element by additive manufacturing, wherein a plurality of continuous thermoplastic filaments filled with reinforcing fibers are continuously heated and three dimensionally formed such that the filaments are crossing and bonded to each other at a plurality of crossing points to form a three dimensional grid truss integrally formed on the shell element. A corresponding structural component and an aircraft or spacecraft including such a structural component are also described.
