Abstract
A structural reinforcing member is provided to improve localized stiffness in frames, rails, body cavities or other such areas found in automotive, marine or aviation applications. The reinforcing member includes a frame having a first and second arm extending laterally therefrom. The frame is configured to be securely positioned in the area of interest. A thermally expandable material is disposed on the arms such that a gap is formed between the thermally expandable material of the first arm and the adjacent second arm prior to expansion. A bake process allows the expandable material to expand around the immediate area, thereby providing localized stiffness and support.
