Various embodiments relate to a radar-absorbing material having a honeycomb sandwich structure. The radar-absorbing material can absorb broadband electromagnetic waves by using electromagnetic properties of a dielectric fiber coated with metal. The radar-absorbing material comprises: at least two honeycomb core layers in which hexagonal units are consecutively arranged with a material including the dielectric fiber coated with metal; and skin layers arranged on the upper surfaces and the lower surfaces of the at least two honeycomb core layers, and including a bottom layer, an uppermost layer, and an intermediate layer. Various other embodiments are possible.

    La présente invention concerne, selon divers modes de réalisation, un matériau absorbant les ondes radar ayant une structure sandwich en nid d'abeilles. Le matériau absorbant les ondes radar peut absorber des ondes électromagnétiques à large bande à l'aide de propriétés électromagnétiques d'une fibre diélectrique revêtue de métal. Le matériau absorbant les ondes radar comprend : au moins deux couches centrales en nid d'abeilles dans lesquelles des unités hexagonales sont disposées consécutivement avec un matériau comprenant la fibre diélectrique revêtue de métal ; et des couches de peau disposées sur les surfaces supérieures et les surfaces inférieures desdites couches centrales en nid d'abeilles, et comprenant une couche inférieure, une couche supérieure et une couche intermédiaire. Divers autres modes de réalisation sont possibles.
