Verbundwerkstoff mit geringer Reflexion auftreffender elektromagnetischer WellenComposite material with low reflection of incident electromagnetic waves
Die Erfindung betrifft einen Verbundwerkstoff, der auftreffende elektromagnetische Wellen -vorzugsweise RAOAR-Strahlung in militärisch genutzten Wellenbereichen- nur wenig reflektiert.The invention relates to a composite material, the incident electromagnetic waves -preferably RAOAR radiation in wave ranges used by the military little reflected.
Dazu muß die elektromagnetische Energie der auftreffenden Welle möglichst weitgehend in Wärme umgewandelt werden.For this purpose, the electromagnetic energy of the incident wave must be converted as much as possible into heat will.
Ausgehend von der bekannten Wirkungsweise ( vor allem dem Antennendiagramm) der Rahmenantenne ist die Aufgabe erfindungsgemäß dadurch gelöst, daß die ankommenden elektromagnetischen Wellen auf eine Vielzahl von kleinen, ringförmigen Rahmenantennen aus dünner Kohlefaser treffen, die in einen Grundwerkstoff eingebettet sind.The task is based on the known mode of operation (especially the antenna diagram) of the loop antenna solved according to the invention in that the incoming electromagnetic waves on a variety of small, meet ring-shaped frame antennas made of thin carbon fiber, which are embedded in a base material.
Die Kohlefaserringe sindThe carbon fiber rings are
-so orientiert, daß die Achsen durch ihre Flächeiimittelpunkte etwa orthogonal zur Wellen-Fortschreitungsrichtung sind, um den Wellen maximal Energie zu entziehen;-oriented in such a way that the axes pass through their surface centers are roughly orthogonal to the direction of wave propagation in order to extract maximum energy from the waves;
-in einen Grundwerkstoff (vorzugsweise Kunstharz) so eingebettet, daß in Abstimmung mit dessen Dielektrizitätskonstante, mit Ringdurchmessern, Faserdicke, Anzahl der Ringe die Dämpfung einfallender Wellen im interessierenden Frequenzbereich maximal wird;-in a base material (preferably synthetic resin) embedded in such a way that, in coordination with its dielectric constant, with ring diameter, fiber thickness, number of rings the damping of incident waves in the interesting Frequency range becomes maximum;
-zur Erzielung eines hohen Absorptionsgrades in Bezug auf die Wellen-Fortschreitungsrichtung mehrfach/gestaffelt hintereinander angeordnet.- to achieve a high degree of absorption in relation to the direction of wave propagation multiple / staggered arranged one behind the other.
