Title (EN) METHODS, PRECURSORS AND ABRASIVE BLASTING MASKS FOR MANUFACTURING NOISE ATTENUATING DEVICES
(FR) PROCÉDÉS, PRÉCURSEURS ET MASQUES DE DÉCAPAGE PAR PROJECTION D'ABRASIFS DESTINÉS À LA FABRICATION DE DISPOSITIFS ATTÉNUATEURS DE BRUIT
Abstract:
(EN) Noise attenuating devices and methods, precursors and abrasive blasting masks for manufacturing noise attenuating devices are disclosed. An exemplary method disclosed herein comprises bonding a facing sheet (12) of the noise attenuating device (10) to a cellular core (14) and then perforating (18) the facing sheet. Perforating the facing sheet may be performed by abrasive blasting using a mask (26) configured to prevent the abrasive blasting of an underlying structure.
(FR) La présente invention concerne des dispositifs atténuateurs de bruit ainsi que des procédés, des précurseurs et des masques de décapage par projection d'abrasifs destinés à la fabrication de dispositifs atténuateurs de bruit. Un procédé exemplaire de la présente invention consiste à lier une feuille de parement (12) du dispositif atténuateur de bruit (10) à une âme alvéolaire (14), et à ensuite perforer (18) la feuille de parement. La perforation de la feuille de parement peut être effectuée par décapage par projection d'abrasifs en utilisant un masque (26) conçu pour empêcher le décapage par projection d'abrasifs d'une structure sous-jacente.
