Abstract

Manufacturing an acoustic panel by bonding with prior heat treatment. The invention relates to a method for manufacturing an acoustic panel (100) comprising the assembly of at least one first element (130) with a second element (120), the method comprising: - the application of at least one adhesive film (520) comprising a plurality of orifices (521) onto an assembly face (130a) of the first element (130) comprising openings, the centers of the orifices (521) of the adhesive film (520) coinciding with the centers of the openings on the assembly face (130a), - a first heat treatment of the adhesive film (520) such that said adhesive film (520) shrinks and hardens, - bringing the second element (120) into contact with the assembly face (130a) of the first element (130), - a second heat treatment of the adhesive film (520) so as to fix the first element (130) to the second element (120).
