Verfahren (110) zur Herstellung eines gehärteten Elements, wobei das Verfahren (110) die folgenden Schritte umfasst: - Bereitstellen (112) eines Komposite-Elements (114), welches eine eine äußere Oberfläche (116) bildende Schicht aufweist, wobei die die äußere Oberfläche (116) bildende Schicht mindestens ein ungehärtetes Duroplastsystem oder mindestens ein ungehärtetes Thermoplastsystem und Verstärkungsfasern (118) aufweist, wobei die Verstärkungsfasern (118) zumindest teilweise in das Duroplastsystem oder Thermoplastsystem eingebettet sind, - Applizieren (120) mindestens einer ersten Folienschicht (122) auf die die äußere Oberfläche (116) bildende Schicht, wobei die mindestens eine erste Folienschicht (122) in einer Drehrichtung (124) entgegen einer Faserapplikationsrichtung (126) der Verstärkungsfasern (118) der äußeren Oberfläche (116) appliziert wird.
摘要:
Method and device for producing a tube, sleeve or reinforcing coating from threads (5) or bands with or without a curable matrix. The tube, sleeve or coating (1) is spun on a core element (4) and pulled off this as it hardens to a stable form while a cable or a tube which will be protected by the sleeve (1) is pulled through the core element (4) at the same time as the sleeve (1) is pulled off the core element (4) in such a way that the sleeve stays around the cable or the tube which it is intended to protect.

A duct of fibre material and binder agent, at least two fold lines are present lengthwise for providing a foldability of the duct by weakened material along the fold lines. The duct is pushable into a folded state and the material remembers the original shape and return to its original shape when released from a folded state. A method of manufacturing a duct: applying a web of origin fibre material with binder agent to a core and compressing the web by an outside form under the influence of heat against the core, wherein the core and/or the outside form is provided with a number of lengthwise ridges corresponding to the desired number of fold lines, to a third of the original thickness of the sides and at the ridges a tenth to a twentieth of the original thickness, and in that the fibre and binder agent web weighs 1,5-3 kg/m2.
摘要:
An elongated web or strip (200) comprising a wall portion bounded by edge portions and adapted to form a conduit by spirally winding said web and joining adjacent edge portions. The edge portions (210, 220) are adapted to permit relative movement between adjacent portions of the spiral conduit and thereby provide radial alteration of the conduit. The web includes a compensation portion (300) to alter the dimension of the web (200) upon radial alteration of the conduit and thereby compensate for creep in the spiral conduit. In a particularly preferred embodiment the edge portion comprises a primary lock (214, 224) and a secondary or sacrificial lock (212, 222). The sacrificial lock is disengaged by release of the mechanism 215 to permit relative movement there between and thereby effect radial alteration of the conduit.
