Abstract

Die Erfindung betrifft ein Faserverbund-Halbzeug (1), aufweisend eine untere (2) und eine obere Deckschicht (3) mit Fasern (6), wobei die untere Deckschicht (2) parallel zur oberen Deckschicht (3) angeordnet ist, wobei zwischen der unteren (2) und der oberen Deckschicht (3) Ellipsoid-förmige Glasschaum-Elemente (4) in zumindest zwei parallelen Ebenen angeordnet sind, wobei in jeder Ebene die Glasschaum-Elemente (4) in einem kartesischen Gitter angeordnet sind und die Gitterpunkte zweier benachbarter paralleler Ebenen in Richtung der Ebenen derart zueinander versetzt sind, dass die kartesischen Gitterpunkte in der einen der beiden benachbarten Ebenen zwischen den kartesischen Gitterpunkten in der anderen der beiden benachbarten Ebenen angeordnet sind, wobei zwischen den Ellipsoid-förmigen Glasschaum-Elementen (4) Fasern (6) und Bindematerial (7) angeordnet sind, wobei die Glasschaum-Elemente (4) an deren Oberflächen Rippen (13) aufweisen, wobei die Rippen (13) der Glasschaum-Elemente (4) mit Rippen (13) von in benachbarten Ebenen angeordneten benachbarten Glasschaum-Elementen (4) ineinandergreifen. Weiters betrifft die Erfindung ein Verfahren zur Herstellung von Faserverbund-Halbzeug (1).The invention relates to a fiber composite semifinished product (1), comprising a lower (2) and an upper cover layer (3) with fibers (6), wherein the lower cover layer (2) is arranged parallel to the upper cover layer (3), wherein between lower (2) and the upper cover layer (3) ellipsoidal glass foam elements (4) are arranged in at least two parallel planes, wherein in each plane the glass foam elements (4) are arranged in a Cartesian grid and the lattice points of two adjacent parallel planes in the direction of the planes are offset from each other such that the Cartesian grid points are arranged in the one of the two adjacent planes between the Cartesian grid points in the other of the two adjacent planes, wherein between the ellipsoidal glass foam elements (4) fibers ( 6) and binding material (7) are arranged, wherein the glass foam elements (4) on their surfaces ribs (13), wherein the ribs (13) of the glass foam elements (4) engage with ribs (13) of adjacent glass foam elements (4) arranged in adjacent planes. Furthermore, the invention relates to a method for producing fiber composite semifinished product (1).

Claims (3)

Patentansprüche:claims: 1. Faserverbund-Halbzeug (1), aufweisend eine untere (2) und eine obere Deckschicht (3) mit Fasern (6), wobei die untere Deckschicht (2) parallel zur oberen Deckschicht (3) angeordnet ist, wobei zwischen der unteren (2) und der oberen Deckschicht (3) Ellipsoid-förmige Glasschaum-Elemente (4) in zumindest zwei parallelen Ebenen angeordnet sind, wobei in jeder Ebene die Glasschaum-Elemente (4) in einem kartesischen Gitter angeordnet sind und die Gitterpunkte zweier benachbarter paralleler Ebenen in Richtung der Ebenen derart zueinander versetzt sind, dass die kartesischen Gitterpunkte in der einen der beiden benachbarten Ebenen zwischen den kartesischen Gitterpunkten in der anderen der beiden benachbarten Ebenen angeordnet sind, wobei zwischen den Ellipsoid-förmigen Glasschaum-Elementen (4) Fasern (6) und Bindematerial (7) angeordnet sind, wobei die Glasschaum-Elemente (4) an deren Oberflächen Rippen (13) aufweisen, wobei die Rippen (13) der Glasschaum-Elemente (4) mit Rippen (13) von in benachbarten Ebenen angeordneten benachbarten Glasschaum-Elementen (4) ineinandergreifen.1. Semi-finished fiber composite (1), comprising a lower (2) and an upper cover layer (3) with fibers (6), the lower cover layer (2) being arranged parallel to the upper cover layer (3), with between the lower ( 2) and the top cover layer (3) ellipsoid-shaped glass foam elements (4) are arranged in at least two parallel planes, the glass foam elements (4) being arranged in a Cartesian grid in each plane and the grid points of two adjacent parallel planes are offset from one another in the direction of the planes in such a way that the Cartesian grid points in one of the two adjacent planes are arranged between the Cartesian grid points in the other of the two adjacent planes, fibers (6) between the ellipsoidal glass foam elements (4) and binding material (7) are arranged, the glass foam elements (4) having ribs (13) on their surfaces, the ribs (13) of the glass foam elements (4) having ribs (13) from Interlocking adjacent glass foam elements (4) arranged in adjacent levels. 2. Verfahren zur Herstellung von Faserverbund-Halbzeug (1), wobei zwischen zwei parallel angeordneten Deckschichten (2,3) mit Fasern Ellipsoid-förmige Glasschaum-Elemente (4) in zumindest zwei parallelen Ebenen angeordnet werden, wobei in jeder Ebene die Glasschaum-Elemente (4) in einem kartesischen Gitter angeordnet werden und die Gitterpunkte zweier benachbarter paralleler Ebenen in Richtung der Ebenen derart zueinander versetzt sind, dass die kartesischen Gitterpunkte in der einen der beiden benachbarten Ebenen zwischen den kartesischen Gitterpunkten in der anderen der beiden benachbarten Ebenen angeordnet werden, wobei zwischen den Ellipsoid-förmigen Glasschaum-Elementen (4) Fasern (6) und Bindematerial (7) angeordnet werden, wobei die Glasschaum-Elemente (4) an deren Oberflächen Rippen (13) aufweisen, wobei die Rippen (13) der Glasschaum-Elemente (4) mit Rippen 2. A process for the production of semi-finished fiber composite (1), wherein ellipsoid-shaped glass foam elements (4) are arranged in at least two parallel planes between two cover layers (2, 3) with fibers, the glass foam in each plane Elements (4) are arranged in a Cartesian grid and the grid points of two adjacent parallel planes are offset from one another in the direction of the planes such that the Cartesian grid points in one of the two adjacent planes are arranged between the Cartesian grid points in the other of the two adjacent planes wherein fibers (6) and binding material (7) are arranged between the ellipsoidal glass foam elements (4), the glass foam elements (4) having ribs (13) on their surfaces, the ribs (13) being the glass foam -Elements (4) with ribs 10 / 11 [ ZULETZT VORGELEGTE ANSPRÜCHE ] (13) von in benachbarten Ebenen angeordneten benachbarten Glasschaum-Elementen (4) ineinandergreifen, wobei die Rippen (13) beim Ineinandergreifen brechen.10/11 [LAST CLAIMS] (13) of adjacent glass foam elements (4) arranged in adjacent planes interlock, the ribs (13) breaking when they interlock. 3. Verfahren nach Anspruch 2, dadurch gekennzeichnet, dass die zwei parallel angeordneten Deckschichten (2,3) in Form von Bändern zueinander versetzt angeordnet werden, wobei die versetzten Bänder zusammen mit den Glasschaum-Elementen (4) zwischen den zwei Deckschichten (2,3) zu einem stabförmigen Faserverbund-Halbzeug (1) aufgewickelt werden, wobei eine der zwei Deckschichten (2,3) zu einer äußeren Schicht und die andere der zwei Deckschichten (2,3) zu einer inneren Schicht des stabförmigen Faserverbund-Halbzeugs (25) gebildet wird, wobei innerhalb der inneren Schicht des stabförmigen Faserverbund-Halbzeugs (25) ein Hohlraum (24) ausgebildet wird.3. The method according to claim 2, characterized in that the two cover layers (2, 3) arranged in parallel are arranged offset in the form of strips, the offset strips together with the glass foam elements (4) between the two cover layers (2, 3) are wound into a rod-shaped fiber composite semifinished product (1), one of the two cover layers (2, 3) forming an outer layer and the other of the two cover layers (2,3) forming an inner layer of the rod-shaped fiber composite semifinished product (25 ) is formed, a cavity (24) being formed within the inner layer of the rod-shaped fiber composite semi-finished product (25).
