Abstract
Methods for reducing vibration or noise that is transmitted by or through a relatively thin, flat, rigid sheet of material such as a glass pane (e.g., the windshield of a vehicle) or metal panel are provided, wherein such a panel is provided with a material between the panel and a frame that is capable of causing attenuation of the noise or vibration propagating from the panel to the frame or vice versa. Such an assembly is especially useful for glazing in a vehicle for the purpose of improving acoustic comfort within the vehicle.
Claims24
An assembly comprising a) a panel having at least one edge, b) a carrier, and c) a high damping foam, wherein said edge is at least partially encased by said high damping foam, said high damping foam is at least partially contained by said carrier, and said carrier is adapted to fit into and/or attach to a frame.
An article of manufacture comprising a) a panel having at least one edge, b) a carrier, c) a high damping foam, and d) a frame, wherein said edge is at least partially encased by said high damping foam, said high damping foam is at least partially contained by said carrier, and said carrier is attached to said frame.
The article of manufacture of claim 11, wherein the edge of the panel does not contact the carrier.
The article of manufacture of claim 11, wherein said article of manufacture is a vehicle or a component of a vehicle.
The article of manufacture of claim 11, wherein said carrier is channel-shaped.
The article of manufacture of claim 11, wherein said frame is comprised of metal.
A method of making an assembly, said method comprising a) placing an edge of a panel within a carrier containing one or more portions of heat activatable expandable resin and b) heating said one or more portions of heat activatable expandable resin under conditions effective to convert said one or more portions of heat activatable resin to a high damping foam which at least partially encases said edge and which is at least partially contained by said carrier.
The method of claim 23, wherein the edge of the panel does not contact the carrier.
The method of claim 23, wherein said carrier is channel-shaped.
A method of making an article of manufacture, said method comprising a) placing an edge of a panel within a carrier containing one or more portions of heat activatable expandable resin to form an assembly, b) attaching said assembly to a frame using at least one adhesive and/or one or more mechanical fasteners, and c) heating said one or more portions of heat activatable expandable resin under conditions effective to convert said one or more portions of heat activatable resin to a high damping foam which at least partially encases said edge and which is at least partially contained by said carrier.
A method of making an assembly, said method comprising placing an edge of a panel within a carrier containing one or more portions of a high damping foam such that said high damping foam at least partially encases said edge and is at least partially contained by said carrier.
A method of making an assembly, said method comprising a) placing an edge of a panel within a recess of a portion of a high damping foam such that said high damping foam at least partially encases said edge and b) placing said portion of said high damping foam within a carrier such that said portion of said high damping foam is at least partially contained by said carrier.
A method of making an assembly, said method comprising a) placing an edge of a panel within a recess of a portion of a heat activatable expandable resin, b) placing said portion of said heat activatable expandable resin within a carrier, and c) heating said portion of said heat activatable expandable resin under conditions effective to convert said portion of heat activatable resin to a high damping foam which at least partially encases said edge and which is at least partially contained by said carrier.
