Description

Die Erfindung bezieht sich auf ein Verfahren nach dem Oberbe­ griff des Anspruchs 1.
Nach dem gattungsgemäßen Verfahren hergestellte Bauteile weisen Verbindungsmittel auf, die die Lagen wenigstens teilweise annä­ hernd senkrecht durchdringen. Hierdurch wird die zwischen den Lagen bestehende Schälfestigkeit erhöht.
Die DE-OS 22 61 024 zeigt einen faserverstärkten Aufbau, insbe­ sondere in Gestalt einer Triebwerks-Kompressorschaufel, wobei die einzelnen Lagen des Materials durch Querverbindungen in Form metallischer Nadeln oder Klammern miteinander verbunden sind. Diese Querverbindungen werden einzeln vor dem Aushärten des Kunststoffs mittels einer druckluftbetriebenen Heftpistole ein­ gebracht.
Der US-PS 38 37 985 ist ein multidirektional verstärktes Ver­ bundbauteil entnehmbar, zu dessen Herstellung die Querverbindun­ gen in die noch nicht ausgehärteten Faserlaminate eingebracht werden, und zwar in Form von Nadeln oder Stiften, die aus bereits ausgehärtetem faserverstärktem Kunststoff bestehen.
In beiden Fällen geschieht das Einbringen der Querverbindungen anhand relativ komplizierter Einrichtungen. Hiermit werden die einzelnen Klammern oder Nadeln gezielt gesetzt. Dabei ist von Nachteil, daß die entsprechenden kraftbetriebenen Einrichtungen einen hohen Investitionsaufwand erfordern und der Fertigungsab­ lauf durch Einsatz der Einrichtungen nicht nennenswert beschleu­ nigt wird.
Der US-PS 16 57 979 ist ein aus mehreren Lagen von Dachpappe geschichtetes Material zu entnehmen, bei dessen Herstellung die Papplagen eine Zwischenlage aus einer Art Maschendraht erhalten. Die Zwischenlage weist in relativ großer Anzahl querstehende Drahtenden auf. Beim Zusammenpressen der Lagen mittels einer Presse oder mittels Walzen durchdringen diese Enden die Papp­ lagen und werden außen umgebogen, so daß die Papplagen durch eine Art Klammerwirkung zusammengehalten werden. Durch diese Maßnahme wird die Aufgabe gelöst, das geschichtete Material so auszubilden, daß es als Material zum freitragenden Abdecken von Dachkonstruktionen verwendbar ist. Merkmale eines Verfahrens zum Einbringen von Querverbindungen in ein Bauteil aus Lagen von faserverstärktem Kunststoff sind hier nicht ohne weiteres zu entnehmen.
Der Erfindung liegt die Aufgabe zugrunde, bei einem gat­ tungsgemäßen Verfahren das Einbringen der Querverbindungen so zu vereinfachen, daß
  • a) komplizierte Einrichtungen zum Einbringen der Querverbindun­ gen nicht erforderlich sind und
  • b) der Fertigungsablauf beschleunigt wird.
Diese Aufgabe wird bei einem gattungsgemäßen Verfahren durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst.
Eine vorteilhafte Weiterbildung der Erfindung ist im Anspruch 2 angegeben.
Die Erfindung ist anhand der Zeichnung dargestellt und in der Beispielbeschreibung näher erläutert. Es zeigen
Fig. 1 in auseinandergezogener Darstellung mehrere Pre­ preglagen und ein doppelseitiges Nadelband und
Fig. 2 die Prepreglagen nach Fig. 1 in verpreßtem und ausgehärteten Zustand.
Die Fig. 1 zeigt in schematischer Darstellung mehrere Prepregla­ gen 1, d.h. Lagen aus faserverstärktem aushärtbarem Kunststoff, zwischen denen sich ein doppelseitiges Nadelband 2 befindet. Das Nadelband 2 besteht aus einem Gewebeband 2 a, in das Nadeln 2 b so eingeführt sind, daß sie auf beiden Seiten des Gewebebandes 2 a in gleicher Länge hervorstehen. Bei der Herstellung eines Bau­ teiles wird das Nadelband 2 wie eine Prepregschicht in das betreffende Schichtgelege einlaminiert. Besondere Werkzeuge oder Vorrichtungen sind hierzu nicht erforderlich. Mit diesem Nadel­ band 2 kann ein Bauteil, das örtlich eine über die Festigkeit der Kunststoffmatrix hinausgehende Querfestigkeit aufweisen soll, in einfacher Weise bezüglich der Querfestigkeit verstärkt werden.
Fig. 2 zeigt ein aus den Prepreglagen 1 und dem Nadelband 2 fertig gepreßtes und ausgehärtetes Bauteil 3. Beim Verpressen sind die Enden der Nadeln 2 b etwas umgebogen. Hierdurch entsteht eine Klammerwirkung, die den Verbund der Prepreglagen 1 noch wesentlich verbessert und die betreffende Querfestigkeit weiter erhöht.
Bei der Herstellung des Bauteils 3 lassen sich Laminatdicken von etwa 0,5 bis 5 mm herstellen, wobei die genannte Klammerwirkung durch Verwendung von Nadeln 2 b mit entsprechenden Längenzugaben erreicht wird. Der gegenseitige Abstand der Nadeln 2 b kann je nach den konstruktiven Gegebenheiten zwischen 0,5 und 5 mm schwanken.
