Abstract
A formed panel construction and method are provided for portable acoustic partitions of the type which are assembled and configured to create workstations in open office plans. Each partition panel includes a freestanding, open frame with a pair of formed cover panels detachably connected to the opposite sides of the frame to enclose the partition. Each cover panel comprises a laminated composite sheet, which includes a sound absorbant backing sheet constructed from heat fusible fibers, and an overlying upholstery sheet with a finished exterior surface. The composite sheet is heated to soften or plasticize the heat fusible fibers, and is compressed and molded while heated to a predetermined geometrically solid shape, such as a five-sided panel having a flat face and four marginal flanges extending at an angle therefrom. The heat and compression process interconnects the various layers of the composite sheet, and the molded shape creates a one-piece, frameless acoustic cover panel with a stiffness or rigidity which facilitates manual handling, and suspension attachment to the frame without sagging.
