Fiber composite component for absorbing energy

摘要

In the case of a fiber composite component for energy absorption in the event of a crash for an aircraft or spacecraft, the fiber composite component is formed as a laminate construction made of CFRP layers and at least one integrated metal foil portion which is corrosion-resistant with respect to the CFRP layers. A fuselage structure portion of an aircraft or spacecraft is formed using at least one fiber composite component of this type. An aircraft or spacecraft comprises a fuselage structure portion of this type.

1. A fiber composite component for impact energy absorption in a fuselage section of an aircraft or spacecraft;
wherein the fiber composite component extends in a three dimensional laminated form and the fiber composite component comprising: a web portion having a width and extending in a longitudinal direction, a plurality of side portions applied substantially at right angles to the web portion and extending in a longitudinal direction, wherein the width of the web portion decreases in the longitudinal direction from one end to another end, a plurality of CFRP layers, and at least one integrated metal foil layer extending substantially in the same direction as a plurality of fibers of the fiber composite component, wherein said at least one integrated metal foil layer is corrosion resistant with respect to the CFRP layers, having a ductility of at least 20%, and wherein said at least one integrated metal foil layer is arranged between at least two CFRP layers, and is pretreated at a plurality of preferred points so as to provide a predetermined buckling in a direction at the plurality of preferred points absorb forces in the event of a crash of the aircraft or spacecraft through deformation work.
