  • Honeycomb noise attenuation structure
    Patent number: 4539244
    Abstract: Broad band noise attenuation sandwich panels utilizing a cellular core positioned between and bonded to two facing sheets by an adhesive bonding system. One facing sheet is perforated and the other imperforate. A thin sheet of porous fibrous felt or fabric is bonded to the outer surface of the perforate sheet. The adhesive layer, at least between the perforate sheet and the porous fibrous material, is sufficiently thick to isolate the two components and form a funnel shaped opening necked down at the entrance to each perforation.
    Type: Grant
    Filed: February 29, 1984
    Date of Patent: September 3, 1985
    Assignee: Rohr Industries, Inc.
    Inventors: Stanley L. Beggs, Frank J. Riel, Dale W. R. Lawson
  • Honeycomb noise attenuating structures
    Patent number: 4384020
    Abstract: Honeycomb noise attenuation sandwich panels and method of construction having a cellular core positioned between and bonded to two facing sheets. One facing sheet is perforated and the other imperforate. A thin sheet of porous fibrous felt or fabric is bonded to the perforated sheet. The core cells communicate with the atmosphere through the perforated sheet and the pores of the fibrous sheet.

  • Method of manufacture of honeycomb noise attenuation structure and the resulting structure produced thereby
    Patent number: 4254171
    Abstract: Method of manufacturing broad band noise attenuation sandwich panels utilizing a cellular core positioned between and bonded to two facing sheets by an adhesive bonding system. One facing sheet is perforated and the other imperforate. A thin sheet of porous fibrous felt or fabric is bonded to the outer surface of the perforate sheet. The adhesive layer, at least between the perforate sheet and the porous fibrous material, is sufficiently thick to isolate the two components and form a funnel shaped opening necked down at the entrance to each perforation. In one embodiment a thin layer of non-metallic cloth is positioned between the perforated and porous fibrous material in those areas where cutting, trimming or drilling of the completed structure is required to maintain isolation.
