Abstract
A process for producing an acoustically resistive layer, particularly for the nacelles of aircraft jet engines. The process includes producing a structural component by using thermoplastic resins, this component having a given quantity of open surface relative to the acoustic waves to be treated. The structural component is connected to an acoustic metallic fabric having a mesh adapted to the open surface quantity of the structural component. Then, the thermoplastic resin is heated under pressure at high temperature.
