Device and method for producing a structural thermoplastic part

A production device configured to be integrated to a primary structure of an aeroplane, said production device comprising a structural part being formed from a draft part comprising reinforcing fibres embedded in a thermoplastic matrix, the production device comprising:

• a member for supporting a draft part, the support member extending along a longitudinal axis,
• at least one heating member configured to heat a local portion of the draft part at a temperature making it possible to make the thermoplastic matrix of the draft part malleable,
• at least one cooling member configured to cool the local portion of the draft part at a temperature making it possible to solidify the thermoplastic matrix of the draft part,
• at least one main compression member configured to compress the local portion of the draft part against the support member so as to decrease the porosity thereof, the main compression member being situated between the heating member and the cooling member, and
• a system for moving from upstream to downstream along the longitudinal axis of the heating member, of the compression member and of the cooling member relative to the support member so as to consolidate each local portion of the draft part successively.
