  • Method of manufacture of honeycomb noise attenuation structure for high temperature applications
    Patent number: 4522859
    Abstract: Method of manufacturing broad band attenuation panel structure and the resulting structure therefrom for utilization in high temperature applications, having a maximum temperature in the range of 1600.degree. F. The panel comprises a cellular core constructed of Inconel, titanium alloys, 321 stainless steel, P H hardened stainless steel and the like, positioned between and brazed, liquid interface diffusion (LID) bonded, or diffusion bonded to two facing sheets, one imperforate and one perforated, the facing sheets constructed of a similar material. A sheet of porous metal overlay made of Inconel, nickel, monel, stainless steel alloys or the like is diffusion bonded to the outer surface of the perforated facing sheet.The sequential steps of sizing, cleaning, plating, and heating are set forth as well as the details of pressure, temperature, and protective atmosphere, and protective materials.

  • Multi-layer honeycomb thermo-barrier material
    Patent number: 4336292
    Abstract: A thermal barrier material comprising at least four vertically stacked cellular cores separated with septum sheets and enclosed at the outer periphery by facing sheets. The components making up the thermal barrier material may be constructed of titanium alloy, TD nickel, niobium, or the like. In one embodiment, one outer facing sheet is highly polished for use as a reflective surface.

  • Method of diffusion bonding and brazing of materials
    Patent number: 4029254
    Abstract: A diffusion and brazing method of bonding honeycomb core material to its facing sheets wherein the core and facing sheets have a predetermined configuration and either the facing sheets or the core edges have had deposited thereon a laminate formed of diffusion bridge or braze alloy material. First, the faying surfaces of the facing sheets and the core are positioned together with the core located between the facing sheets to form the assembly. Secondly, a male plug is inserted into the interior of the assembly wherein the dimensions of the male plug are slightly smaller than the interior dimensions of the asembly and wherein the male plug is formed from a metal having a thermal coefficient of expansion greater than that of the material of the facing sheets and core.
