摘要:
A method of making a composite part including an insert and an elastomer layer that is bonded to the insert. The insert is placed in a mold and an uncured elastomer is sprayed into the mold to form a composite part. The inherent adhesive properties of the uncured elastomer is the sole mechanism for bonding the elastomer to the insert.

The present invention relates to a composite shoddy for use in a vehicle interior. To this end, the composite shoddy of the present invention includes an organic material having a predetermined density defining shoddy bottom layer and a scrim material having a predetermined density defining a scrim top layer. The scrim top layer is adapted to operatively engage a surface material and accommodate movement of a surface material in the shear direction. The composite shoddy further includes a bituminous mastic material having a predetermined density defining a mastic middle layer. The mastic middle layer is disposed between the shoddy bottom layer and the scrim top layer.

A method of making an acoustic insulator includes depositing thermoplastic particulate on a first surface of a base layer. The method further includes heating the particulate such that the particulate at least partially melts and penetrates the first surface of the base layer, thereby increasing density and airflow resistance of the base layer proximate the first surface such that the base layer has an areal mass in the range of 0.1 to 1.0 kg/m2 and an airflow resistance in the range of 300 to 5,000 Nsm−3 proximate the first surface.

摘要:
A ceiling baffle includes a glass cloth faced fibrous glass board, grooved and folded to provide a double thickness of board. End caps for the folded board are each provided with blade portions extending between the two thicknesses of board and with a hole in an upper wall portion for receiving a barb portion of a suspension clip attachable to an inverted T-bar of a ceiling grid system for mounting ceiling panels.
