Abstract

The composite material consists of an outer layer made from metal sheet, a core structure for rigidity in the form of a honeycomb, and an inner layer made of foil with low elongation at rupture, covering the honeycomb core on the inside. The honeycomb core may be attached to the outer sheet by an adhesive.

Description

Die vorliegende Erfindung betrifft den Aufbau von Motorhauben, wobei es insbesondere um die Verringerung der Gefahr für Leib und Leben geht, wenn es zu einem Anfahren eines Fußgängers kommt und dieser mit dem Kopf auf die Motorhaube geschleudert wird. Das Verformungsverhalten der heute üblichen Motorhauben ist für solche Fälle nicht optimiert. The present invention relates to the structure of Bonnets, particularly reducing Danger to life and limb if there is one A pedestrian hits and the head is opened the bonnet is thrown. The Deformation behavior of today's hoods is for such cases not optimized.

Bedingt durch die anatomischen Eigenschaften des menschlichen Schädels ist ein Verformungsverhalten anzustreben, bei dem die Motorhaube zunächst wenig verformt wird, bei Überschreiten einer unterhalb der kritischen Kraftwirkung auf den Schädel liegenden Kraft jedoch plötzlich nachgibt und sich erheblich weiter verformt, sodaß die wirkenden Kräfte begrenzt bleiben. Due to the anatomical properties of the human skull is a deformation behavior to strive for, where the bonnet initially deforms little will, if one is exceeded below the critical The effect of force on the skull lies however suddenly gives way and deforms considerably, so that the acting forces remain limited.

Erfindungsgemäß kann diese Aufgabe gelöst werden durch einen Schichtaufbau des flächigen Motorhaubenmaterials, und zwar in der Weise, daß eine Außenschicht aus metallischem Blech verbunden ist mit einer festigkeitsverleihenden Kernstruktur aus einer Wabenkonstruktion und diese auf der Innenseite überzogen ist von einer Innenschicht aus einer Folie mit geringer Reißdehnung. According to the invention, this object can be achieved by a layer structure of the flat bonnet material, and in such a way that an outer layer is connected to a metal sheet core structure from a honeycomb structure and this one is covered on the inside Inner layer made of a film with low elongation at break.

Vorteilhafterweise wird das Außenblech mit dem Wabenkern durch Kleben verbunden. The outer sheet with the honeycomb core is advantageously connected by gluing.
