Abstract

A system and method for reinforcing at least a portion of a structural member (16), including at least one hollow carrier (12), having an exterior shell (20) and an interior portion, which substantially conforms to the dimensions and geometry of the structural member (16) being reinforced; and a lightweight, low density material (14) for filling the interior portion of one or more of the carriers (12). The material (14) filling one or more of the carriers (12) of the present invention can be a reinforcement material, self-curing material, or a heat activated expandable material. The carrier (12) can be produced by blow molding or rotational molding and has an adhesive material (24) disposed along at least a portion of the exterior shell (20) used to place, adhere, and affix the carrier (12) to a targeted portion of the structural member (16) selected to be structurally reinforced.
