摘要： The invention relates to a fabric for lightweight nautical sails, such as spinnakers, asymmetric spinnakers, and gennakers, for sailboats and other surface vessels, the fabric being formed of continuous polyester warp and weft yarns and being coated on one or both of its two surfaces with a crosslinked polymer, characterised in that the polyester is poly(ethylene terephthalate) (PET) having a tenacity greater than or equal to 6 cN/dtex; in that the fabric has a density of between 20 and 50 threads/cm, in terms of warp and weft density; in that the polymer is a crosslinked polyurethane (PU) that is polyether-, polyester-, or polycarbonate based; and in that this PU is derived from the crosslinking (1) of a single-component polyurethane elastomer having a modulus at 100% elongation comprised between 1 and 15 MPa, better still between 2 and 15 MPa, in particular between 6 and 15 MPa, according to the standard DIN 53504, used in implementation in solvent phase; and (2) by a crosslinking agent, based on a proportion of dry crosslinking agent relative to the dry elastomer of between 20% and 75% by weight, in particular between approximately 30% and approximately 75% by weight. The coated fabric has an elongation in the bias direction under 20 Lbs, comprised between 10 and 30 hundredths of an inch.

摘要： A disclosed reinforcer includes a shrinkable layer able to shrink in a direction of shrinkage, under the effect of a heat-shrink heat treatment, from an initial state to a shrunk state, a first corrugatable layer, which includes a gridwork of filaments added against the shrinkable layer and connected to the shrinkable layer by connection lines spaced apart and extending transversely with respect to the direction of shrinkage, the first corrugatable layer exhibiting a shrinkage that is substantially zero or that is smaller than that of the shrinkable layer, so that, when the shrinkable layer is in the initial state, portions of the first corrugatable layer, each defined between two consecutive connection lines, are bent over and, when the shrinkable layer is in the shrunk state, the portions of the first corrugatable layer are curved.

摘要： The preform made of a 3D fibrous structure comprises at least 3 layers (1, 2) of weft yarns and/or warp yarns, the structure being woven as a single part by multilayer weaving between a plurality of layers of warp yarns and a plurality of layers of weft yarns. It comprises a predetermined distribution of points of intersection of warp yarn and weft yarn that are bonded by polymer. The polymer represents a mass of less than or equal to 10%. The preform comprises at least one thermoformed portion in which the warp yarns and the weft yarns are bonded at the intersections thereof by polymer where at least one of the warp and/or weft yarns bears polymer.

摘要： The invention relates to a method and facility for manufacturing a tape of reinforcement filaments impregnated by a polymer matrix, said tape having a constant width across the entire length thereof, wherein the filaments extend in a direction parallel to the length of the tape, from a strand of filaments coming from a feeding reel, the method including steps and units that make it possible to manage the unwinding tension of the strand, to guide the strand on the axis of the machine, to manage the width of the strand, to deposit the polymer on the strand by electrostatic powdering, with a polymer weight ratio of around 20% to around 75% to melt the polymer, to calibrate the width and thickness of the tape and to collect the tape on the storage reel.

摘要： This shaping structure (1) comprises two shaping sheets (5, 7) facing each other at a distance from one another. According to the invention, the shaping structure (1) further comprises a macroporous spacer sheet (9), the spacer sheet (9) being arranged between the two shaping sheets (5, 7) and being corrugated in such a way as to form a series of alternating even peaks (18) and odd peaks (20) distributed in a first direction (D1) of the shaping structure, at least one of the even peaks (18) being attached to the first shaping sheet (5), at least one of the odd peaks (20) being attached to the second shaping sheet (7), each peak (18, 20) attached in this way defining an attachment surface (22, 26) for attachment to the shaping sheet (5, 7) to which this peak (18, 20) is attached.

摘要： Said preform (3) defining two parts (21, 23) and comprising: a first group (C1) of layers of warp yarns, which is external in the first part, a second group (C2) of layers of warp yarns immediately beneath said first group, and a first group (T1) of layers of weft yarns which is external in the first part. Furthermore, the first group of layers of warp yarns is absent in the second part and the first group of layers of weft yarns (19) extends into the second part, the first group of layers of weft yarns being external in the second part. The yarns of the first weft group have a lower yarn count than the yarns of the second weft group; and/or the yarns of the first warp group have a lower yarn count than the yarns of the second warp group.
