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

What is claimed is: 1. A reinforcement system for a structural member, the system comprising: a carrier defining a chamber wherein the chamber is filled internally with a reinforcing material; and an adhesive material along a portion of the exterior of the chamber of the carrier, the adhesive material being activatable, upon exposure to heat encountered in an automotive paint operation, to form a structural foam. 2. A reinforcement system as in claim 1 wherein the chamber is formed of a blow molded plastic. 3. A reinforcement system as in claim 1, wherein the reinforcing material filling the carrier comprises a multiplicity of pellets. 4. A reinforcement system as in claim 1, wherein the reinforcing material filling the carrier is formed from a pumpable foamable material. 5. A reinforcement system as in claim 1 wherein the reinforcing material of said carrier is a relatively low density material. 6. A reinforcement system as in claim 1 further comprising one or more mechanical retainers attached to the carrier for assisting in placement of the carrier member relative to a structure. 7. A reinforcement system as in claim 1 wherein the adhesive material is a foamable epoxy based material. 8. A reinforcement system as in claim 1 wherein the carrier includes a port for intake of the reinforcing material. 9. A reinforcement system as in claim 1 further comprising an integral neck portion having an end portion for coupling the carrier to an outside filling apparatus for filling an amount of the reinforcing material into the cavity of the carrier. 10. A reinforcement system for a structural member, the system comprising: a carrier defining a plastic chamber wherein the chamber is filled internally with a foam reinforcing material; and an activatable adhesive material along a portion of the exterior of the plastic chamber of the carrier for forming a reinforcement member; wherein the reinforcement member is located within a cavity of a structural member of an automotive vehicle and, upon exposure to heat encountered in an automotive paint operation, the activatable adhesive material forms a structural foam adhered to the carrier and the structural member. 11. A reinforcement system as in claim 10 wherein the chamber is formed of a blow molded plastic. 12. A reinforcement system as in claim 10 wherein the reinforcing material of said carrier is a relatively low density material. 13. A reinforcement system as in claim 10 further comprising one or more mechanical retainers attached to the reinforcement member for assisting in placement of the carrier member relative to the structural member. 14. A reinforcement system as in claim 10 wherein the adhesive material is a foamable epoxy based material. 15. A reinforcement system as in claim 10 wherein the structural member is an automotive frame or rail. 16. A reinforcement system as in claim 10 wherein the structural member is a portion of an automotive pillar. 17. A reinforcement system as in claim 10 wherein the carrier includes a port for intake of the reinforcing material. 18. A reinforcement system as in claim 10 further comprising an integral neck portion having an end portion for coupling the carrier to an outside filling apparatus for filling an amount of the reinforcing material into the cavity of the carrier. 19. A reinforcement system as in claim 10 wherein the system further comprises one or more mechanical retainers attached to the carrier for assisting in placement of the carrier member relative to a structure. 20. A reinforcement system as in claim 19 further comprising an integral neck portion having an end portion for coupling the carrier to an outside filling apparatus for filling an amount of the reinforcing material into the cavity of the carrier. 21. A reinforcement system as in claim 20 wherein the paint operation is an e-coat bake and the reinforcing foam material is a polyurethane foam.
