A modular segmented structural reinforcement system for use with closed forms or cavities defined with automotive vehicles having a plurality of modular segments designed to be secured within a defined portion of an automotive vehicle applications. An expandable or bonding material, such as an epoxy-based reinforcing foam or other sound absorption, damping, vibration reduction, or sealing material is disposed on at least a portion of the outer surface of each of the plurality of segments. Once the system is flexible fitted within the closed form or placed within a selected cavity of an automotive vehicle, the material expands and cures during an automobile assembly operation, bonding the reinforcement system to the segments. As a result, the reinforcement system provides enhanced load distribution over the vehicle frame without adding excessive weight and further serves to reduce noise and vibrational characteristics of the automotive vehicle.

1. A method of reinforcing a structure of an automotive vehicle, comprising:providing a structure of an automotive vehicle, the structure having a plurality of walls defining a cavity; locating a plurality of modular segments within the cavity wherein the plurality of modular segments includes a first segment, a second segment and a third segment, both the first segment and the second segment having expandable material disposed upon outer surfaces thereof and wherein each of the second segment and the third segment, only after insertion within the cavity, engages another of the plurality of segments that is already within the cavity; activating the expandable material of the first segment to expand, contact and adhere to the second segment; and activating the expandable material of the second segment to expand, contact and adhere to the walls defining the cavity of the structure of the automotive vehicle. 2. A method as in claim 1 wherein each segment of the plurality of the segments is shaped to the contours of the cavity.3. A method as in claim 1 wherein a singular retaining member is disposed through each of the plurality of segments during the locating step.4. A method as in claim 1 wherein the third segment includes an annular outer surface upon which the expandable material is disposed.5. A method as in claim 4 wherein the expandable material, upon expansion, adheres to the walls of the structure and forms the plurality of segments into a unitary structure.6. A method as in claim 1 wherein said expandable material is an expandable foam that is generally free of tack to the touch.7. A method as in claim 1 the structure being selected from a pillar, a rail or a combination thereof.8. A method as in claim 1 wherein each segment of the plurality of segments includes a first portion and a second portion and the plurality of modular segments are maintained in an accordion-like state with the first portion of the first segment of the plurality of modular segments located at least partially within a cavity defined in the second portion of the second segment of the plurality of modular segments.9. A method of reinforcing a structure of an automotive vehicle, comprising:providing a structure of an automotive vehicle, the structure having a plurality of walls defining a cavity; locating a first segment of a plurality of modular segments within the cavity; slideably engaging a second segment of the plurality of modular segments with the first segment of the plurality of modular segments, both the first segment and second segment having expandable material disposed upon their outer surfaces; activating the expandable material of the first segment to expand, contact and adhere to the second segment; and activating the expandable material of the second segment to expand, contact and adhere to the walls defining the cavity of the structure of the automotive vehicle; wherein a singular retaining member is disposed through each of the plurality of segments during the slideably engaging step. 10. A method as in claim 9 further comprising:slideably engaging a third segment of the plurality of modular segments with the second segment of the plurality of modular segments. 11. A method as in claim 9 wherein each segment of the plurality of the segments is shaped to the contours of the cavity.12. A method as in claim 9 wherein the outer surfaces are annular and the expandable material, upon expansion, adheres to the walls of the structure and forms the plurality of segments into a unitary structure.13. A method as in claim 9 wherein said expandable material is an expandable foam that is generally free of tack to the touch.14. A method as in claim 9 wherein each segment of the plurality of segments includes a first portion and a second portion and the plurality of modular segments are maintained in an accordion-like state with the first portion of a first segment of the plurality of modular segments located at least partially within a cavity defined in the second portion of a second segment of the plurality of modular segments.15. A method of reinforcing a structure of an automotive vehicle, comprising:providing a structure of an automotive vehicle, the structure having a plurality of walls defining a cavity; locating a first segment of a plurality of modular segments within the cavity; slideably engaging a second segment of the plurality of modular segments with the first segment of the plurality of modular segments, both the first segment and second segment having expandable material disposed upon their outer surfaces, wherein: i) the first segment of the plurality of segments flexibly nests with the second segment of the plurality of segments such that the first segment and second segment can make accordion motions relative to each other; and ii) each segment of the plurality of modular segments successively engages another of the plurality of modular segments, the plurality of modular segments including the first segment, the second segment and a third segment; activating the expandable material of the first segment to expand, contact and adhere to the second segment; and activating the expandable material of the second segment to expand, contact and adhere to the walls defining the cavity of the structure of the automotive vehicle. 16. A method as in claim 15 wherein each segment of the plurality of the segments is shaped to the contours of the cavity.17. A method as in claim 15 wherein the structure is a hydroform tube.18. A method as in claim 15 wherein the expandable material, upon expansion, adheres to the walls of the structure and forms the plurality of segments into a unitary structure.19. A method as in claim 15 wherein said expandable material is an expandable foam that is generally free of tack to the touch.
