  • Method of producing the composite metal-and-plastic components of an antiballistic grill for an armored vehicle
    Patent number: 6174398
    Abstract: A method of fabricating the composite metal-and-plastic components of an antiballistic grill for an armored vehicle. Each component comprises a core in the form of a length of structural section with layers of plastic against each side bonded to the core by heat and pressure in a mold comprising two halves. The object of the present invention is simpler and more economical lamination in the fabrication of non-flat work with a metal core. The core is electrically heated to a prescribed processing temperature by regulating a current of electricity, whereby the resulting heat is employed to soften to a prescribed extent adhesive between the core and the layers of plastic to be bonded to it.
