Abstract
This process for producing a thermoplastic composite part by laying of at least one thermoplastic composite layer on a tool includes laying on the tool a hardened first ply before the laying of the thermoplastic composite layer. The first ply is produced beforehand to the shape of the tool and includes a first material able to experience an attractive force when it is subjected to a magnetic field, and/or to an electrical potential difference, and includes a second material of a thermoplastic resin that is chemically compatible with the resin of the thermoplastic composite layer. The first ply is clamped to the tool by the effect of a magnetic field, and/or of an electrical potential difference, established at the level of the tool. In one form of implementation, the first ply is produced on a first-ply mold that is preferably of convex shape.
