Abstract:
A twisted FRP structure having sufficient strength and flexibility is produced by providing a rod member disposed centrally and twist a plurality of side strands twisted around the rod member in the same direction at a predetermined pitch. At least the side strand includes a composite strand having an FRP element from by impregnating fibers with an uncured thermosetting resin and a thermoplastic coating on such FRP element, the thermosetting resin being cured after the side strands are twisted around the rod member. The twisting pitch is not less than 25 times the outside diameter of the FRP element in the side strand.
Abstract:
An aramid fiber rope having a central core surrounded with aramid fiber rope strands. The core and the aramid strands are coated with a heavy viscous lubricant prior to winding the strands into rope. The lubricated rope is then impregnated and surrounded with a plastic material to entrap the lubricant in the core and the strands.
Abstract:
A composite cord used in the reinforcement of pneumatic tires is composed of a plurality of twisted steel strands cabled around a multifilament core.
Abstract:
The present invention is to provide a hybrid core rope (1) which does not require maintenance or a hybrid core rope (1) capable of reducing a maintenance task. The hybrid core rope (1) includes a resin solid core (2) in which a plurality of spiral grooves (2a) is formed in the longitudinal direction on an outer peripheral surface thereof, a plurality of fiber bundles (3) respectively spirally wound around the outer peripheral surface of the resin solid core (2) along the plurality of spiral grooves (2a), the fiber bundles (3) having thickness to fill the spiral grooves (2a), and a plurality of steel strands (4) spirally wound around the outer peripheral surface of the resin solid core (2) around which the fiber bundles (3)are wound. The fiber bundles (3) and the strands (4) are respectively wound so as to have angles which are not parallel to each other.

Abstract:
Die Erfindung betrifft einen Verstärkungskord (1) für elastomere Erzeugnisse, insbesondere für eine Karkasslage oder eine Gürtellage eines Fahrzeugluftreifens, bestehend aus einer Seele (2) aus einem nicht-metallischen Werkstoff und aus wenigstens vier Stahl-Lagenfilamenten (4), wobei die Stahl-Lagenfilamente (4) um die Seele (2) herum verseilt sind. Der Erfindung liegt die Aufgabe zu Grunde, einen alternativen Verstärkungskord bereitzustellen, der eine hohe Festigkeit und Biegesteifigkeit aufweist, aber dennoch vergleichsweise leicht an Gewicht ist. Die Aufgabe wird gelöst, indem die Seele (2) aus wenigstens einem Seelenfilamentgarn, -zwirn oder -kord (3) aus dem Werkstoff Glasfaser besteht und indem die Stahl-Lagenfilamente (4) um die Seele (2) herum offen verseilt sind, so dass der Kord (1) bis zur Seele (2) mit Gummi durchdringbar ist.
Abstract:
Drahtseil (1), insbesondere Seilbahn-Tragseil, mit einem Kern, der von zumindest einer äußeren Lage (8, 10-13) von Seilelementen (9) umgeben ist, und der zumindest einen zur Datenübertragung vorgesehenen Lichtwellenleiter (3) aufweist, der in einem Metallröhrchen (5) eingebettete Glasfasern (6) enthält und der mit zumindest einem Draht (4, 4') zu einem Spiralseil (2) verseilt ist; dabei ist das Kern-Spiralseil (2) von einem Kunststoffmantel (7) umgeben, der eine Schutzhülle gegenüber der zumindest einen äußeren Seilelemente-Lage (8, 10-13) bildet.
