Abstract

Der Faserverbundwerkstoff besteht aus einzelnen Schichten übereinander angeordneter und durch eine, aus einem Harz und Härter bestehenden Matrix miteinander verbundener gerichteter Faserlagen, z. B. Glasfaserpre­ pregs, als tragende Struktur zur Absorption elektromagneti­ scher Wellen. Dazu sind in den einzelnen Schichten des Faserverbundwerkstoffes (7) Radarstrahlung absorbieren­ de Füllstoffe (10), z.B. Eisenpulver oder Ruß, mit von außen nach innen variierender Konzentration eingelagert.
