    摘要： There is disclosed a drop-in ceiling tile or the like together with method of making the same wherein expanded polystyrene in a large block is cut into substrate sheets approximately two feet by four feet by three-quarters to one inch thick using a hot-wire cutter, which substrate sheet thereafter is provided with a thin facing of vinyl plastic stretch resistant sheet, e.g. rigid PVC, about 0.001 to about 0.005 inches in thickness having nearly invisible perforations therein to facilitate the escape of moisture from water base adhesive utilized to laminate the vinyl sheet onto the expanded polystyrene substrate. The vinyl sheet will previously have been textured in a conventional manner or otherwise decorated, in a preferred embodiment. The product and method of making it is adapted to rapid repetitive batch processing with a maximum of a few hours from start of sheet cutting to finish and packaging of the product thereby allowing production on demand with minimal storage space requirements or investment in finished product.

    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.
