A method for forming a thermoplastic composite material with continuous fiber reinforcement by stamping. A flat blank comprising a pre-consolidated stack of plies by automatic fiber placement of fibers referred to as the thermoplastic pre-impregnated fibers is obtained. The flat blank is reheated to a temperature greater than or equal to the melting temperature of the thermoplastic polymer making up the matrix of the thermoplastic pre-impregnated fibers. The reheated flat blank is hot stamped and the part formed between the stamping punch and die is consolidated.
