Abstract
A three-dimensional laminate beam is formed by inserting a preformed foam core insert within a hydra-formed metal section having curved three-dimensional geometry. A reinforcing polymer is pumped in and around the foam core insert so as to be adjacent the inside wall of the shell. The polymer bonds to the inside wall of the shell upon the polymer being cured.
