In a process to make a strengthening material, filaments produced in a hotmelt spinning assembly are combined in roving or a tape and are impregnated with a thermoplastic agent to form a matrix. The hotmelt spinning assembly discharges the matrix as a foil, which is then drafted. In the drafting process, the thermoplastic material is stretched, while the fibers are fractured. The foil may then be cut into strips of width typically 3 - 30 mm. |
