Patent ID: 6880657

Claim:
A method of reinforcing or baffling a structure of an automotive vehicle with a structural assembly, comprising: (a) providing a structural assembly including: i) a first member having a first surface generally opposite a second surface; ii) a second member having a first surface generally opposite a second surface; iii) an expandable material intermediate the first member and the second member, the expandable material being different from a first material forming the first member and a second material forming the second member, the first material being the same or different than the second material; iv) one or more fasteners assisting in attaching the first and second member together; (b) positioning the structural assembly within a cavity defined by the automotive vehicle structure such that the second surfaces of the first and second members respectively oppose a first surface and a second surface that at least partially define the cavity; (c) expanding the expandable material between the first surfaces of the first and second members thereby promoting connection of the second surfaces of the first and second members with the first surface and the second surface that at least partially define the cavity.
