Abstract
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 (B, B). The method comprises the following steps: a) before the edge-to-edge junction of blocks with a cellular core (B, B), opening the cells (A, A) located on the edges of the blocks to be joined; and b) edge-to-edge dry joining the blocks (B, B) so that the open cells (A, A) engage into one another.
