Abstract
There is described a process for manufacturing a dimensionally stable, three-dimensionally shaped, sheetlike textile material by bringing one or more layers of a deep-drawable textile material made of yarns, preferably a knitted material, and containing reinforcing fibers and a thermoplastic matrix material in fiber form which melts at a lower temperature than the reinforcing fibers, into the shape desired for the core material by an area-enlarging shaping process, for example by deep-drawing, at a temperature at which the fibrous thermoplastic matrix material melts, then reducing the temperature to back down to below the melting point of the thermoplastic matrix material and keeping the shaped material in the mold until the thermoplastic matrix material has sufficiently hardened, and then demolding the resulting shaped textile material.
