摘要： The present invention relates to a method for producing a three-dimensional preform consisting in producing an initial preform (4) comprising a plurality of stacked plies, said plies being formed from unidirectional continuous fibres and a first polymer, and thermoforming the initial preform between the male forming tool (92) and the female forming tool (91) of a press (9) in order to obtain a three-dimensional preform (1). During the forming step, an outer web is positioned at the interface between the initial preform (4) and the male tool (62) and at the interface between the initial preform and the female tool (91), said outer webs being formed from a second polymer such that, during the forming step, the outer webs remain in a solid state and are deformed.
