Producing fiber reinforced foam materials for aircraft involves engaging through hole from first surface to engage at least one fiber bundle and pulling bundle(s) into through hole in foam material

The method involves making a through hole (2) in the foam material (1) extending between first and second surfaces of the foam material, preparing at least one fiber bundle (3) on the other side of the second surface of the foam material, engaging through the hole starting from the first surface to...

Zusammenfassung:	The method involves making a through hole (2) in the foam material (1) extending between first and second surfaces of the foam material, preparing at least one fiber bundle (3) on the other side of the second surface of the foam material, engaging through the hole starting from the first surface to engage at least one fiber bundle and pulling the at least one bundle into the through hole in the foam material. Independent claims are also included for the following: (A) a composite core material (B) and an aircraft with an inventive material. Die Erfindung betrifft ein Verfahren zur Verstärkung von Schaumwerkstoffen (1), einen verstärkten Kernverbund (5) sowie ein entsprechend ausgestattetes Flugzeug. Bei dem Verfahren wird ein Schaumwerkstoff (1) mit Faserbündeln (3) versehen, die mit einer Nadel (8) in den Schaumwerkstoff (1) eingebracht werden. Dabei wird mit der Nadel (8) zunächst von einer Seite aus ein Durchgangsloch (2) in den Schaumwerkstoff (1) gestochen, um dann ein auf der anderen Seite befindliches Faserbündel (3) mit der Nadel (8) aufzugreifen und in den Schaumwerkstoff (1) einziehen zu können.
