Abstract
The invention relates to a process for manufacturing a composite molded structure including the steps of: depositing first and second members in a mold; inserting at least one flexible plastic membrane between the first and second members so as to form a sheath when the mold is closed; closing the mold; injecting into the sheath reactants intended to react to form a foam which expands in situ and stretches the sheath until it forces the members flat against the walls of the mold; cooling the contents of the mold; and opening the mold to withdraw the composite molded structure.
