Abstract
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.
