  • Composite structure and method of manufacturing it
    Patent number: 4641726
    Abstract: A panel having a cellular core and an acoustically semi-transparent facing is provided. The core, which may be a honeycomb, has cells opening to a face of the core. The facing is bonded to the face of the core such that pillow-like portions of the facing extend into the open cells of the core to provide a mechanical interlock between the facing and the core and to improve the absorption of acoustic energy directed upon the panel. The panel may include a layer bonded to the core opposite the facing for reducing the transmission of acoustic energy through the panel or for increasing its strength and rigidity. Preferably, the facing is non-homogeneous such that the density of the pillow-like portions is less than the portions of the facing adjacent the structure of the core. The panel may be formed by heating and compressing an uncured fibrous element of relatively uniform thickness and density against a cellular core. A heated platen may be used to produce a relatively flat, hardened outer surface of the panel.
    Type: Grant

    Date of Patent: February 10, 1987
