Abstract
A method for the hot stamping of a composite part with continuous fiber reinforcement in a thermoplastic matrix. A blank including a laminated structure of plies consisting in unidirectional tapes of fibers pre-impregnated with thermoplastic polymer is obtained. The blank is heated in the open to a temperature greater than or equal to the melting temperature of the polymer making up the matrix. The blank is then stamped.
