ABSTRACT:
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.
