Title: TEXTILE SUBSTRATE MADE OF REINFORCEMENT FIBRES
Abstract:
The invention relates to a textile substrate made of reinforcement fibres for producing composite-material preforms, comprising a unidirectional laid fabric made of at least one sheet-like ply of multifilament reinforcement yarns that are arranged parallel to and alongside one another and are connected together via cross threads, wherein a nonwoven made of thermoplastic polymer material is arranged on the at least one sheet-like ply of multifilament reinforcement yarns, said nonwoven being adhesively connected to the sheet-like ply of multifilament reinforcement yarns. The textile substrate is characterized in that the cross threads have a core-sheath structure having a first component making up the sheath and a second component making up the core, wherein the first component has a lower melting point than the second component, the first component is a meltable thermoplastic polymer material and the multifilament reinforcement yarns arranged alongside one another are connected together by melt bonding via the first component of the cross threads.
