A method of making an acoustic absorption structure comprising a skin forming a plurality of enclosures, an acoustic absorption structure obtained by said method and an aircraft comprising said acoustic absorption structure
Method for producing an acoustic absorption structure comprising a skin forming a plurality of enclosures, an acoustic absorption structure obtained according to said method and an aircraft comprising said acoustic absorption structure The subject of the invention is a method for producing a sound absorption structure comprising an acoustically resistive structure, a honeycomb structure (54), a reflective layer as well as a plurality of acoustic elements positioned in the honeycomb structure (54), against the acoustically resistive structure, the method comprising : a step of forming a skin (68) forming enclosures of the acoustic elements by attaching a resin to a mold (74) having a base (76) on which are positioned protruding shapes (78) shaped as the delimited cavities by the enclosures of the acoustic elements, a step of docking the mold (74) supporting the resin and the honeycomb structure (54), the resin being both interposed between the mold (74) and the honeycomb structure (54), a resin polymerization step in order to simultaneously obtain hardening of the skin (68) as well as the junction between the skin (68) and the honeycomb structure (54), and a step of placing the acoustically resistive structure and the reflective layer.
