Abstract

Abstract Translated from German Der Faserverbundwerkstoff besteht aus einzelnen Schichten übereinander angeordneter und durch eine, aus einem Harz und Härter bestehenden Matrix miteinander verbundener gerichteter Faserlagen, z.B. Glasfaserprepregs, als tragende Struktur zur Absorption elektromagnetischer Wellen. Dazu sind in den einzelnen Schichten des Faserverbundwerkstoffes (7) Radarstrahlung absorbierende Füllstoffe (10), z.B. Eisenpulver oder Ruß, mit von außen nach innen variierender Konzentration eingelagert. The fiber composite material consists of individual layers of fiber layers arranged one above the other and connected to one another by a matrix consisting of a resin and hardener, for example glass fiber prepregs, as a supporting structure for the absorption of electromagnetic waves. For this purpose, fillers (10), for example iron powder or soot, absorbing radar radiation are stored in the individual layers of the fiber composite material (7) with a concentration that varies from the outside inwards.
