Abstract: A lengthwise extended component contains of a support that possesses flow channels in the direction of its longitudinal axis. The support additionally possesses external surfaces that are offset to each other in the direction of the longitudinal axis as well as a lateral external surface. These external surfaces are provided with a layer of a thermally expansible and curable composition. Reinforcing components of this type are suitable for stiffening and/or reinforcing hollow supports, such as the A-, B- or C-pillars, the roof edges or the rocker panels of vehicles, especially passenger cars.

Abstract: Motor vehicles designed as station wagons having a large roof opening have a tendency toward body shaking. To minimize body shaking, at least one foam composite component is provided in the node region of a rear pillar and an additional body structural component. The foam composite component includes a base body which is coated in places with a foam material. As the result of heat treatment the foam material expands and fills the cavity in the node region in a manner which increases rigidity.
