The invention relates to a method for making an acoustic absorption panel in particular for the nacelle of an aircraft engine, the panel being of the type comprising a cellular core covered on one side with a so-called outer air-permissive skin and on the other side with a so-called inner perforated skin, the cellular core being formed by the edge-to-edge junction of a plurality of blocks with a cellular core (B1, B2). The method comprises the following steps: a) before the edge-to-edge junction of blocks with a cellular core (B1, B2), opening the cells (A1, A2) located on the edges of the blocks to be joined; and b) edge-to-edge dry joining the blocks (B1, B2) so that the open cells (A1, A2) engage into one another.

L'invention concerne un procédé de fabrication d'un panneau d'absorption acoustique notamment pour nacelle de moteur d'aéronef, ce panneau étant du type comprenant au moins une âme alvéolaire revêtue sur l'une de ses faces d'une peau dite externe perméable à l'air et sur l'autre de ses faces d'une peau dite interne perforée, cette âme alvéolaire étant formée par la jonction bord-à-bord d'une pluralité de blocs à âmes alvéolaires (B1, B2). Ce procédé comprend les étapes consistant : a) préalablement à la jonction bord-à-bord des blocs à âmes alvéolaires (B1, B2), à ouvrir les alvéoles (A1, A2) situées sur les bords des blocs destinés à être joints, et b) à joindre bord-à-bord et à sec ces blocs (B1, B2) de manière que les alvéoles ouvertes (A1, A2) s'imbriquent les unes dans les autres.
