Abstract (en)
[origin: US4581284A] A fiber compound material of individual layers of superposed fiber plies such as glass fiber prepregs which are joined together by a matrix of a resin and a hardener and act as a load carrying structure to absorb electromagnetic waves. Radar beam-absorbing fillers, for instance iron powder or soot, are included, in concentrations varying from the outside to the inside, in the individual plies of the fiber compound material.
Abstract (de)
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.
