  • Method of casting fail-safe composite metal structure
    Patent number: 5392840
    Abstract: A method for manufacturing a structural component includes forming a groove in an outer surface of a fiber reinforced body. Molten metal is introduced to an exposed surface of the groove and to a predetermined portion of the outer surface of the body. The metal is cooled in a controlled manner to thermally alter sufficient resin to create a secure interconnection of the metal on the body. The metal adjacent the groove is sized so that it will fail prior to separation of the metal from the body under excessive tensile loads. A portion of the metal remains on the body so that elongation of the component significantly exceeds ultimate elongation of the fiber reinforced body and the cast metal.
    Type: Grant
    Filed: May 17, 1994
    Date of Patent: February 28, 1995
    Assignee: General Motors Corporation
