Method for manufacturing noise-attenuating devices using abrasive blasting masks
A recently granted patent (Publication Number: US11911873B2) discloses a method for manufacturing a noise-attenuating device involving bonding a facing sheet to a cellular core and then perforating the facing sheet using abrasive blasting. The method includes producing an abrasive blasting mask by applying a photosensitive masking material on the facing sheet and selectively exposing it to light to create holes in specific regions. The patent also details the use of data representative of the cellular core's position to generate images for the perforation process, ensuring precise and controlled perforation of the facing sheet.
Furthermore, the patent describes a precursor for manufacturing a noise attenuating device, comprising a cellular core, an imperforated facing sheet bonded to the core, and a mask overlaying the facing sheet to prevent abrasive blasting at specific locations. The mask is produced using photosensitive masking material and images projected onto it to create holes in desired regions. The method outlined in the patent aims to improve the manufacturing process of noise-attenuating devices by ensuring accurate perforation of the facing sheet while avoiding damage to the cellular core structure. Additionally, the use of data for image generation enhances the precision and efficiency of the perforation process, ultimately leading to the production of high-quality noise-attenuating devices.
