Multilayer anti-drumming and stiffening sheeting
First Claim
1. A multilayer anti-drumming and stiffening sheeting for use with a sheet metal element which has a predetermined configuration and which is heated during fabrication of an article, the multilayer anti-drumming and stiffening sheeting comprising:
- an anti-drumming sheeting which includes a mass and a filler, and a stiffening sheeting which includes a thermosetting material adapted to conform to the predetermined configuration after heating, the stiffening sheeting being integrally connected to the anti-drumming sheeting.

Abstract
A multilayer sheeting for attachment to sheet metal to stiffen the sheet metal and diminish noise. An anti-drumming sheeting consisting of a filler embedded in a mass such as a bituminous material may be bonded to sheet metal, such as the sheet metal employed in manufacture of an automobile door, and a stiffening sheeting which may consist of a matrix such as a fiberglass mat drenched in a thermosetting resin is bonded to the anti-drumming sheeting. Such a multilayer anti-drumming and stiffening sheeting is flexible enough during application to conform to the configuration of the sheet metal, but hardens into a rigid lining component when the sheet metal is heat treated during the normal course of fabrication.
