Abstract
An impulse-absorbing structural component, particularly for an aircraft, has an impulse-absorbing layer and a covering layer applied thereto. The impulse-absorbing layer is made of a material that has a higher capacity for elongation at its breaking point than does the covering layer, and has a regular pattern of elevations and depressions. If a mass impacts on the covering layer, an intercept bag forms in the impulse-absorbing layer, and absorbs the kinetic energy of the mass. Viewed in the direction of the spread of the intercept bag, the structural component has structure beyond the impulse-absorbing layer, such that the formation of the intercept bag can take place without further interaction with the structural component.
Claims8
An impulse-absorbing structural component of an aircraft, said structural component comprising:
- an impulse-absorbing layer;
- and
- a covering layer applied to the impulse-absorbing layer, said covering layer being made of a carbon-fiber referenced plastics material;
- wherein,
- the impulse-absorbing layer is made of a glass-fiber reinforced plastics material, and has a higher elongation at a breaking point than the covering layer;
- the impulse-absorbing layer has a regular pattern of elevations and depressions, whereby upon impact of a mass on the covering layer, an intercept bag forms in the impulse-absorbing layer and dissipates kinetic energy of the mass;
- and
- viewed in the direction of the spread of the intercept bag, the structural component has an open structure beyond the impulse-absorbing layer, such that the formation of the intercept bag can take place without further interaction with the structural component.
An impact absorbing structural component of an aircraft, said structural component comprising:
- an impact absorbing layer having an undulating structure that comprises a pattern of elevated portions and depressed portions;
- a cover layer that is detachably attached to the impact absorbing layer along each of said elevated portions, on a side of said impact absorbing layer to be exposed to an impact by a mass;
- wherein,
- the side of the impact absorbing layer opposite the side on which the cover layer is attached is without any further layers;
- the cover layer is made of a carbon-fiber reinforced plastics material;
- and
- the impact absorbing layer is made of a glass-fiber reinforced plastics material that has a greater capacity to stretch prior to reaching a braking point than the carbon-fiber reinforced plastics material of which the covering layer is made.
