ABSTRACT:
A lightweight expandable baffle for sealing a cavity of a vehicle body at a predetermined cross section of the cavity defined by cavity walls includes a rigid support plate having an outer periphery with a shape generally corresponding to but smaller than the shape of the cross section of the cavity, a heat expandable sealing material mounted only to the outer periphery of the rigid support plate and having an activation temperature range at which the material expands, the support plate being formed of a material having a higher melting point than the activation temperature range, and the sealing material, when activated, expands radially from the rigid support plate to fill the cross-sectional cavity between the rigid support plate and the cavity wall.
