A disclosed manufacturing method includes a step for draping a fiber reinforcement, into a plurality of superposed layers, a step for providing resin in the fiber reinforcement, and a step for polymerizing the resin. The method includes, prior to the draping step, a step for making cutouts with a predetermined shape in the fiber reinforcement, and during the draping step, the layers of fiber reinforcement are superposed by putting the cutouts facing each other, the whole of the cutouts of the superposed layers forming a housing at least for an insert.

A belt made up of an elastomeric belt body, an electrically conductive tensile cord such as carbon fiber cord in a cord layer reinforcing the belt body, an outer layer of electrically conductive thermoplastic material such as polypropylene film, and an electrically conductive fabric layer residing between the tensile cord layer and the outer layer and providing electrical continuity between the outer layer and the tensile cord. An electrically conductive thread may be woven in the fabric and may present at both surfaces of the fabric and contact both the outer layer and the tensile cord to provide the electrical continuity there between.

A fabric and elastomeric material (referred to as a fabric trilayer) combined with a sealant may be applied in such a fashion so as to eliminate or minimize air entrapment in an elastomeric composite structure that forms a seal-sealing volume. The performance of the self-sealing volume is dramatically improved with this minimizing of air entrapment. Surprisingly and unexpectedly, this construction approach may be accomplished without significantly adding to the weight or thickness of the volume and without affecting the outer dimension of the self-sealing volume. Thus, a method and system for forming a self-sealing volume are described. The system includes an elastomeric composite structure comprising at least one layer of an elastomeric material derived from a neat (no solvent) elastomeric material that does not substantially react at room temperature.

A molding die and a molding method are provided, which allow high-cycle manufacturing of molded bodies of a thermoplastic resin or thermoplastic resin-fiber composite material, thereby improving productivity. Molding is performed using a molding die including a plurality of die portions that form a cavity in which a molded body is molded, the molding die including: a first temperature adjusting unit disposed in the vicinity of the cavity surface and capable of at least cooling the cavity surface; and a second temperature adjusting unit disposed on a side of the first temperature adjusting unit opposite from the cavity surface and capable of at least heating the cavity surface, wherein a distance L0 from the cavity surface to the first temperature adjusting unit and a distance L1 from the cavity surface to a surface of the corresponding die portion opposite from the cavity surface satisfy the relationship: (L1/L0)>3.

A large-size wind power blade with a multi-beam structure and its manufacturing method, wherein the blade adopts a hollow layout structure and comprises a blade skin suction edge, a blade skin pressure edge, a main load-carrying structure crossbeam and anti-shearing webs, wherein the blade skin suction edge and the blade skin pressure edge are combined to form a cavity structure having a streamlined cross section, wherein a support structure formed by the combination of the main load-carrying structure crossbeam and the anti-shearing web is located in the cavity. Both the blade skin suction edge and the blade skin pressure edge adopt a multi-segment combined structure, wherein the multiple segments are connected to the side surface of the main load-carrying structure crossbeam to integrally form the blade skin suction edge and the skin pressure edge. Under the premise of ensuring the structural rigidity and strength, the anti-bending capability as well as the stability of the blade of the present invention is increased. With the use of high modulus carbon fiber laxer, the weight of the blade is reduced, the load of the blade, especially the fatigue load, is reduced is reduced.

The invention refers to a method for laminating a tubular film (1) preferably manufactured by means of blown film (co-) extrusion with a material capable of absorbing resin or liquids, wherein the tubular film (1) is laminated over its entire perimeter with several layers (10, 11, 12, 13; 20, 21, 22; 30, 31) overlapping or positioned directly opposite one another on their front sides containing material capable of absorbing resin or liquids, so that essentially there are no areas left along the perimeter of the tubular film (1) not covered by the laminated layers (10, 11, 12, 13; 20, 21, 22; 30, 31). The invention also refers to a tubular film laminated in such a way and to various applications.

The invention relates to a process for the production of saturated fiber structures. The process includes (a) introduction of a fiber structure onto a conveyor belt; (b) application of a solution including monomer and optionally including activator, and optionally including catalyst in at least one line to the fiber structure; (c) passage of the fiber structure with the solution through at least one roll pair in which pressure is exerted on the fiber structure; and (d) cooling of the saturated fiber structure, so that the monomer solidifies.
