FOAM INSULATION WITH THERMOFORMABLE FILM COATING AND PROCESS FOR MANUFACTURE

A thermal/acoustic insulation product, such as for an aircraft, comprising a block of flexible, open-celled, cellular foam having a predefined shape and having a thermoformed amorphous film covering that completely envelops the foam block. A process for making the insulation product includes first cutting the block of foam to a predefined shape, such as a shape suitable for placement in an area of an aircraft in need of insulation. Then, a first sheet of film is heated to its melt point and conformed to a first surface area of the block, and a second sheet of film is heated to its melt point and conformed to a second surface area of the block, wherein the first film and the second film are joined to one another at one or more seams. The insulation product may then be installed in an aircraft.

Acoustic abatement panel fabrication

A method of making an aircraft acoustic structural panel (10) begins with preforming a core honeycomb laminate (12) having preformed foam (3) bonded inside cells (14) thereof by a distinct adhesive (2). The preformed honeycomb laminate (12) is then stacked between opposite top and bottom structural outer laminates (16,18). The stacked honeycomb laminate (12) and outer structural laminates (16,18) are then compressed together under heat and pressure into a unitary structural panel (10) having the core honeycomb laminate (12) integrally bonded between outer skins (20,22). The outer laminates (16,18) may include imperforate acoustic septums (4) bounding the core honeycomb laminate (12) followed by an outer honeycomb (5) and structural fiber layers (6, 7, 8) defining the outer skins (20,22).
