The invention pertains to a method for reinforcing cellular materials (1), a reinforced sandwich construction (5) as well as a correspondingly equipped aircraft. In the method, a cellular material (1) is provided with fiber bundles (3) that are introduced into the cellular material (1) with a needle (8). In this case, the needle (8) initially pierces a through-hole (2) into the cellular material (1) from one side in order to subsequently take hold of a fiber bundle (3) situated on the other side with the needle (8) and pull said fiber bundle into the cellular material (1).
