Method for manufacturing a sound attenuation panel

摘要

The present disclosure provides a method for manufacturing a sound attenuation panel having a first cellular core structure and a second cellular core structure joined in a junction area (J). The method includes: a) a joining edge of the first cellular core structure is joined to a corresponding joining edge of the second cellular core structure, thereby forming the junction area; b) the first cellular core structure and the second cellular core structure are placed between an inner skin and an outer skin of the panel.;In particular, the method further has a step prior to step a), in which one junction reinforcement is inserted between the joining edge of the first cellular core structure and the corresponding joining edge of the second cellular core structure in the junction area.

1. A method for manufacturing a sound attenuation panel comprising a first cellular core structure and a second cellular core structure joined in a junction area (J), the first and second cellular core structures each comprising at least one cellular core layer,
wherein: a) a joining edge of the first cellular core structure having a cellular core is joined to a corresponding joining edge of the second cellular core structure having a cellular core, thereby forming the junction area; b) the first cellular core structure and the second cellular core structure are placed between an inner skin and an outer skin of the panel, wherein the method further comprises: a step prior to step a), in which at least one junction reinforcement is inserted between the joining edge of the first cellular core structure and the corresponding joining edge of the second cellular core structure in the junction area, said junction reinforcement extending in a plane transverse to the first and the second cellular core structures, and a subsequent step in which the first and second cellular core structures and the junction reinforcement are secured together using a connecting means, and wherein the junction reinforcement is indexed and fixed on a mold.
