Abstract
There is described a tape comprising unidirectionally oriented reinforcing and thermoplastic fibers composed of yarns of reinforcing and/or thermoplastic fibers, the yarn density being about 5 to 20 yarns/cm of width and the yarns having a linear density of about 1000 to 3000 dtex, the matrix fibers having been locally incipiently or completely melted on at least one of the tape surfaces to form consolidation points. The tape is suitable as a starting material for producing composite materials.
