摘要： A method of laminating a porous overlay material to a perforated plate with a dry film adhesive which does not block perforations or pores in the two components. A lay-up is preferably prepared by assembling in order on a vacuum platen a porous peel ply sheet, a sheet of dry film adhesive, a perforated plate, a sheet of microporous material to be bonded to the perforated plate and an air permeable sheet. A vacuum is drawn through holes in the vacuum platen contiguous to the bottom surface of the porous peel ply sheet while the assembly is heated to the softening temperature of the adhesive film. The vacuum is directly applied through the perforation, drawing the film down through the perforations and into contact with the peel ply sheet. As heating continues the film softens sufficiently to adhesively bond the microporous material to the perforated sheet. When the pack is disassembled, the adhesive extending beyond the holes and into the peel sheet is stripped away with the peel sheet, leaving all of the holes and pores open and the holes coated with the adhesive. The resulting structure is particularly adapted for use in noise suppression structure used in aircraft gas turbines engine housings.

摘要： An improved synthesis for PMR-type polyimides, including first preparing a dimer of 5-norbornene-2,3-dicarboxylic acid, or acid ester or anhydride and 4,4'methylenedianiline. This dimer is then reacted with the reaction product of the dimethyl ester (or dianhydride) of 3,3', 4,4'-benzophenonetetracarboxylic acid and 4,4'-methylenedianiline. The resulting polyimide prepolymer exhibits superior physical properties and is substantially free of the undesired trimer of 5-norbornene-2,3-dicarboxylic acid, or acid ester or anhydride and 4,4'-methylenedianiline. When this dimer is reacted with 3,3', 4,4'-benzophenonetetracarboxylic acid dianhydride methylenedianiline amic acid mixture, the resulting polyimide prepolymer exhibits superior physical properties.

摘要： A method of manufacturing a perforate material from wire mesh for honeycomb noise attenuation and the resulting material therefrom comprising the steps of selecting a sheet of wire mesh, constructed from a material that can be readily diffusion bonded; cleaning the selected wire mesh to remove all grease therefrom, suspending the sheet of selected wire mesh within a furnace, evacuating the oven to about 10..sup.5 torr, elevating and maintaining the furnace temperature to facilitate diffusion bonding of the contacting cross-over areas of the strands of the wire mesh; reducing the furnace temperature, removing the sheet of diffused wire mesh from the oven when its temperature is below its oxidation level. The furnace may additionally be charged with an inert gas to decrease the cooling time. In some instances a heat dispersing member is inserted between the sheet of wire mesh and the source of the elevating temperature. The mesh is selected with hole sizes equal or slightly less in cross-section than the desired diffused size. Where the hole cross-section size is slightly less than ultimately required the hole size is enlarged by conventional chem-milling of the diffused wire mesh.
