摘要： The present invention relates especially to an intermediate material comprising, or even constituted exclusively by, an array of individualised ribbons, each ribbon being composed by a tape of unidirectional reinforcing fibres associated, by adhesion, on each of its faces with a veil of thermoplastic fibres, characterised in that the ribbons are disposed in successive layers, in such a way that the ribbons of two successive layers are superposed with or without crossing but without interlacement, the bond between a ribbon and the ribbon or ribbons with which it is superposed being ensured by adhesion, and in that in each layer the ribbons are disposed substantially parallel to each other over at least the major part of their length, while being independent and spaced from each other and in that the ribbons of at least two layers extend in two different directions.

摘要： Fabric having warp and weft yarns where the filaments in the yarns freely move relatively to each other. The basis weight of the fabric is related to the thickness standard deviation of a stack of three identical fabrics deposited on each other. For basis weights greater than or equal to 40 g/m2 and less than 100 g/m2, the thickness standard deviation is less than or equal to 35 μm. For basis weights greater than or equal to 100 g/m2 and less than or equal to 160 g/m2, the thickness standard deviation is less than or equal to 50 μm. For basis weights greater than 160 g/m2 and less than or equal to 200 g/m2, the thickness standard deviation is less than or equal to 60 μm. For basis weights greater than 200 g/m2 and less than or equal to 400 g/m2, the thickness standard deviation is less than or equal to 90 μm.

摘要： The invention concerns a process for preparing a ribbon of reinforcement strands or filaments associated on each of its faces with a polymeric binder, said ribbon having a given width substantially constant over its entire length, in which the strands or filaments extend in a direction parallel to the length of the ribbon, wherein it comprises the following steps: a) adjustment of the ribbon width to the desired width thanks to a dimensioning device, b) association of the ribbon on each of its faces with a polymeric binder allowing the assurance of a homogenous cohesion of the ribbon, such that the total weight of the binder does not exceed 25% of the total weight of the obtained ribbon, as well as the ribbons obtainable by such a process.

摘要： The invention relates to a composite material in which at least one reinforcement thread is deposited on a surface according to a path having at least one curved area on the deposition surface, wherein the reinforcement thread is connected to the surface by a polymeric binder. A twist is applied to the reinforcement thread before the deposition thereof at least in order to compensate the length differences of the extreme paths of the thread on either side of the width as measured in a direction parallel to the deposition surface.
