Abstract
A reinforcement for an expandable or foaming material is disclosed that comprises a first and a second member each having protuberances that are contacted when the first and second members are joined. The members are joined by bending a hinge that separates the members, or can be joined in multiple units to form a series. The members are maintained in a closed or joined position by at least one latch. Once joined, the first and second members define at least one opening wherein a foaming composition can be injected into the joined members. Alternatively, a preformed expandable material can be placed between the first and second members, or located on selected outer positions, e.g., within an automotive cavity to be sealed.
