Abstract: A method for producing an acoustically resistive structure includes the steps of creating, consolidating and cutting a first layer of reinforcing fibres embedded in a first thermoplastic resin having a first melting point so as to obtain an interlayer, a step of laying a second layer of reinforcing fibres against a first face of the interlayer, a second consolidation step of consolidating the second layer of reinforcing fibres embedded in a second thermoplastic resin having a second consolidation temperature lower than the first melting point of the first resin so as to obtain a non-perforated external layer bound to the interlayer, a step of perforating the external layer and a step of laying an internal layer on a second face of the interlayer. An acoustically resistive structure obtained from the method as well as a sound-absorption panel including such an acoustically resistive structure are also described.

Abstract: Induction welding process for welding two parts using at least one susceptor including discontinuous conductive elements, and assembly of at least two parts obtained using the induction welding process. An induction welding process can join at least first and second parts, and the process can include a step of positioning at least one susceptor, including discontinuous conductive elements, between the first and second contact faces of the first and second parts, and steps of holding the first and second parts pressed against each other and of producing an electromagnetic field to generate an induced current that engenders heating of the susceptor. An assembly of two parts can be obtained using the process.
