- This polyimide foam layer is structured in such a way that, when viewed in plane extension, it faces in a third dimension, ie facing the nonwoven layer superior to this layer or, for example, facing away from this layer of nonwoven layer, by means of area-wise elevations. These can be further formed, for example, by undulations or small pimples or formations.
- a mold-foamed polyimide foam can continue to be used.
- the formed on an upper surface uneven structure of the polyimide foam can also be found on the bottom in the negative, so that according to the invention both surfaces are uneven, three-dimensionally structured, to increase the total surface of the foam layer.

Description
Diese können weiter bspw. durch wellen- oder pockenartige Erhebungen bzw. Ausformungen gebildet sein. Diesbezüglich kann weiter ein formgeschäumter Polyimid-Schaumstoff Verwendung finden. Die auf einer Oberseite ausgebildete unebene Struktur des Polyimid-Schaumstoffes kann sich auch auf der Unterseite im Negativ wiederfinden, so daß erfindungsgemäß beide Oberflächen uneben, dreidimensional strukturiert sind, zur Vergrößerung der Gesamtoberfläche der Schaumstofflage. Im weiteren betrifft die Erfindung auch ein mehrlagiges Isolationselement mit zwei Schaumstofflagen, die in übereinander angeordneten Schichten vorgesehen sind, wobei hier erfindungsgemäß darauf abgezielt ist, daß eine Schaumstofflage aus unebenem, dreidimensional strukturiertem Polyimid-Schaumstoff besteht. Unabhängig vom wahlweisen Schichtaufbau, also Vlieslage mit Schaumstofflage oder zwei Schaumstofflagen, ist in einer bevorzugten Ausgestaltung des Erfindungsgegenstandes vorgesehen, daß die Schaumstofflage aus einem zugeschnittenen Schaumstoff besteht. Besonders bevorzugt ist hierbei, daß die Schaumstofflage zick-zack-förmig verläuft,
wobei dieser Verlauf in Ebenenerstreckung der Schaumstofflage ausgebildet ist. Demzufolge erstrecken sich die durch die Zick-Zack-Form gebildeten Erhebungen in Richtung auf die darüber und/oder darunter angeordnete Lage. Hierdurch wird die über und/oder unter der erfindungsgemäß ausgebildeten Schaumstofflage angeordnete Lage (Vlieslage oder weitere Schaumstofflage) zu der Polyimid-Schaumstofflage beabstandet, womit sich in den Zwickel der Zick-Zack-Form im Querschnitt etwa V-förmige Hohlräume bilden. Als besonders vorteilhaft erweist es sich hierbei, daß über die Dicke und/oder den Winkelverlauf zur Senkrechten der Zick-Zack-Stege ein gewünschtes Schall-Absorbtionsverhalten eingestellt ist. Zufolge dieser Ausgestaltung ist das Schall-Absorbtionsverhalten im Zuge der Herstellung der erfindungsgemäßen Schaumstofflage durch die Wahl der Materialdicke und/oder den Verlauf der Zick-Zack-Struktur voreinstellbar. In weiterer Ausgestaltung des Erfindungsgegenstandes ist vorgesehen, daß die Schaumstofflage ober- und unterseitig von einer Vlieslage überdeckt ist. Hierbei kann es sich jeweils um ein genadeltes, verdichtetes bzw. mechanisch verfestigtes Vlies handeln. Weiter können hier auch Melofilfasern in einem Anteil von 10-70 %, vorzugsweise 50 % zum Einsatz kommen. Weiter ist denkbar, die obere, bevorzugt der Lärmquelle zugewandte Vlieslage als Melt-Blown-Vlies und die untere Lage als thermisch gebundenes Volumenvlies auszubilden. Weiter besteht auch die Möglichkeit, eine Mischung aus Melaminfasern und Basofilfasern zur Herstellung eines dreidimensionalen Gerüstes zu verwenden. Darüber hinaus besteht bei einer Anordnung von mindestens zwei übereinanderliegenden Schichten aus Schaumstoff jede Schaumstofflage aus Polyimid zu bilden, wobei die uneben, dreidimensional strukturierte, bevorzugt zick-zack-förmig strukturierte Polyimid-Schaumstofflage ober- und unterseitig mit einer ebenen, im Verhältnis zur strukturierten Schaumstofflage relativ dünnen Polyimid-Schaumstofflage überdeckt ist. Darüber hinaus können auch zwei Schaumstofflagen vorgesehen sein, zwischen welchen eine Vlieslage vorgesehen ist. Bevorzugt wird hierbei eine Ausgestaltung, bei welcher beide Schaumstofflagen entsprechend den zuvor beschriebenen Ausführungen uneben, dreidimensional strukturiert als Polyimid-Schaumstofflagen ausgebildet sind und die zwischengeschaltete Vlieslage ein Melt-Blown-Vlies ist. Die Lagen des Isolationselementes sind desweiteren von einer Folie umhüllt. Insbesondere besteht diese Umhüllungsfolie aus zwei Folienlagen, welche weiter bevorzugt Außenlagen sind. Diese Folienlagen umhüllen die übereinander angeordneten Isolationsschichten zur Bildung eines kompakten, mehrlagigen Isolationselementes. Auch können die Folienlagen zusätzlich als Zwischenlagen vorgesehen sein. Die Außenfolien sind weiter bevorzugt randverschweißt, jedoch können die Vlies- und/oder Schaumstofflagen sämtlich oder zum Teil mit in die Schweißnaht integriert sein etwa durch eine bis nahe auf Null gehende randverdichtete Vlies- und/oder Schaumstofflagen. Eine solche Randverdichtung kann auch zur Bauteilformgebung genutzt werden. Auch können Befestigungselemente in eine solche Schweißnaht integriert werden. Die Zusammenfügung der Außenfolien ist hierbei geeigneterweise derart, daß der Gesamtverbund allein durch die randverschweißten Folien und gegebenenfalls Vliesund/oder Schaumstofflagen zusammengehalten sind. Eine Verklebung, Kaschierung oder dergleichen der einzelnen Lagen ist nicht erforderlich und bevorzugt auch nicht vorgesehen. Die Lagen sind -jedenfalls außerhalb des Randbereiches- nur einfach übereinander gelegt. Es ergibt sich gleichsam ein Kissen mit einer durch die Außenfolien gebildeten Hülle. Partielle, durch Verschweißungen, insbesondere im Randbereich herbeigeführte Verdichtungen können zur Aufnahme von Befestigungselementen und/oder Versteifungen des Bauteiles beitragen. Die mehreren Lagen (Vlies- und/oder Schaumstofflagen) führen zu einer Art Prallfüllung. Für den Gegenstand ist auch von Bedeutung, daß die Flüssigwasserbildung in dem Bauteil verringert ist. Die verwendeten Folien, sowohl die Außenfolien wie auch gegebenenfalls zwischenfolien weisen unterschiedliche Wasserdurchlässigkeit auf, wobei bevorzugt wasserdampfdurchlässige Membranfolien Verwendung finden. Bevorzugt werden auch Folien verwendet, die richtungsaktive Wasserdampfdurchlässigkeiten aufweisen. Es können auch Folien eingesetzt werden, die feuchtigkeits- und/oder temperaturabhängige Wasserdampfdurchlässigkeiten aufweisen. Weiter können diese Folien auch faserverstärkt sein, wobei diesbezüglich weiter bevorzugt ist, diese Fasern innenseitig der Folie vorzusehen.
