Title: METHOD FOR PRODUCING A TEXTILE UNIDIRECTIONAL FABRIC
Abstract:
The invention relates to a method for producing a textile unidirectional fabric, wherein at least one planar layer of multi-filament reinforcement threads arranged parallel to each other are woven with each other over transverse threads, wherein transverse threads having a core-sheath structure and a titer of 10 to 40 tex are used as transverse threads, wherein the transverse threads have a first component, which structures the sheath, and a second component, which structures the core, wherein the first component has a lower melting temperature than the second component, the first component is a meltable thermoplastic polymer material and, via the first component of the transverse threads, the adjacently arranged multi-filament reinforcement threads are connected to each other by hot melting, wherein alleys are formed in the unidirectional fabric by interweaving the multi-filament reinforcement threads together with the transverse threads, by means of which a permeability of 10 to 600 l/dm2/min can be established. A preferred embodiment relates to a method for producing a unidirectional fabric having a fleece. The invention further relates to a fiber preform, produced from the unidirectional fabric.
