Abstract

A textile substrate made from reinforcing fibers for the production of composite-material preforms, Including an unidirectional composite consisting of at least one flat layer of multifilament reinforcing yarns arranged alongside and parallel to one another and joined by transverse threads, whereby a nonwoven of thermoplastic polymer material is arranged on the at least one flat layer of multifilament reinforcing yarns and is adhesively bonded to the flat layer of multifilament reinforcing yarns. The textile substrate wherein the transverse threads have a core/sheath structure with a first component forming the sheath and a second component forming the core, wherein the first component has a lower melting point than the second component, the first component is a fusible thermoplastic polymer material and the multifilament reinforcing yarns arranged alongside one another are joined together via the first component of the transverse threads by meltbonding.
