    Abstract: Process for manufacturing a composite block of closed geometry, in the form of a continuous ring, based on reinforcing fibres and on a cross-linkable resin, by continuously winding in superposition a predetermined number Nc of layers of a tape of the reinforcing fibres embedded in a matrix based on a composition comprising the cross-linkable resin, the method comprising, from the upstream end downstream, the steps of: producing a rectilinear arrangement (12) of reinforcing fibres (11), and conveying this arrangement in a feed direction (F); degassing the arrangement of fibres (12) under the action of a vacuum (13); after degassing, impregnating the arrangement of fibres (12) with the resin composition in the liquid state (17); passing the pre-preg thus obtained through a die (20) to impose on the per-preg the shape of a tape (21) consisting of the reinforcing fibres (11) in their liquid resin matrix (17), the thickness (Er) of the tape being between 0.1 mm and 0.5 mm; on leaving the die (20), applying a surface treatment (22) to the upper face of the tape (21) in order to create a solid skin the thickness (Ep) of which represents less than 10% of the thickness (Er) of the tape, so that the skin acts as a stable base for the subsequent winding of the tape (21) on itself; depositing the thus superficially treated tape (21) on a support (23) that dictates the final shape of the composite block, and winding the tape (21) onto the support (23), in a single direction, by superposing the number Nc of layers in order directly to form the continuous ring (30) on the support (23), Nc being less than 15.

    Abstract: A process produces a conductive rubber roller having small aspect ratios of inner and outer diameters, having a stable measure of its inner diameter, having uniform cell distribution and being free from non uniformity of hardness and electrical resistance in the peripheral direction. The process has a step of continuously extruding a tube composed of a specific unvulcanized rubber composition from a rubber extruder in a microwave vulcanizing unit, and a step of foaming and vulcanizing the tube by using a microwave irradiator having a microwave irradiation zone 4 m or less in length while being transported at given speed. The foamed rubber tube has an inner diameter 20 to 35% smaller than the outer diameter of the conductive core material over the whole region in the lengthwise direction, and the conductive core material is press fitted into the foamed rubber tube without using any adhesive.

    Abstract: The present invention provides a method and apparatus for curing a coated fiber, comprising either two fiber coating curing stages separated by a cooling stage, or two fiber coating curing stages separated by a distinct time interval, or both. One of the two fiber coating curing stages responds to the coated fiber, and provides a partially cured fiber coating. The other of the two fiber coating curing stages responds to the partially cured coated fiber for further curing the coating of the fiber. In one embodiment of the invention, a cooling stage is placed between the two curing stages, while in the other the curing stages are placed a set distance apart such that polymerization of the coating initiated by the first curing stage has time to complete prior to the coating being irradiated by the second curing stage. The cooling stage is used to actively remove heat generated during the cure process from the fiber coating, while the time delay is used to allow complete polymerization to occur before subsequent irradiations. These embodiments of the present invention can be used separately or in combination to achieve optimal fiber coating cure.

    Abstract: A method of producing a screen for forming a nonwoven material by hydroentanglement. The method includes the steps of providing a layer of radiation curable polymeric resin material in fluid form. Further, the step of irradiating at least one layer of radiation curable polymeric resin material in fluid form through at least one mask selectively transparent to the radiation, so as to effect at least partial curing of the material of the at least one layer in positions corresponding with radiation-transparent regions of the mask. Further still, the step of removing uncured polymeric material to form one or more apertures within the at least one layer. Wherein the radiation-transparent regions of the mask have different sizes and shapes and are distributed randomly, such that the one or more apertures provided in the cured polymeric material of the screen are not provided in a regular pattern or form.

    Abstract: The invention relates to a process for the production of a polymer layer of a flexible unbonded offshore pipe. The process comprises the steps of shaping a polymer material by extrusion into or onto a supporting unit in an extrusion station and cross-linking said extruded polymer material, said polymer material comprising a polyethylene and a peroxide for providing a cross-linking of the polymer material. The peroxide has an activation temperature substantially above the temperature of the polymer material during the extrusion thereof. The cross-linking of the extruded polymer material is carried out by exposing the extruded polymer material to electromagnetic waves, selected from the group consisting of infrared radiation and microwave. The invention also relates to a flexible unbonded offshore pipe comprising such polymer layer.
