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.

Method of producing the composite metal-and-plastic components of an antiballistic grill for an armored vehicle

An attachment between the frame of a grating in a special-purpose vehicle, an armored vehicle for example, and the lengths of structural section that comprise the grating. The ends of the lengths of structural section are secured against displacement by a plate. When the lengths of structural section have a metal core and a non-metal sheath, the core or part of the core is attached to and can or cannot be detached from the frame by way of the plate. The plate is positioned against the surface of the frame component that faces away from the lengths and is provided with cutouts (6) that provide access to the core of each length and allow the introduction of means (5 or 8) of attachment.

Connection of a frame of a grille for special vehicles such as armored

A grating system (1) with parallel lengths (5) of structural section is accommodated in a frame. It is intended for armored special-enough vehicles and or stationary units. The object is to optimize protection against a strike or impact. Energy absorbers are interposed between the system and the vehicle or unit that accommodates it.

Grating system

A connection between frame components (1) and the ends of parallel strips ( 3 ) of structural section in gratings ( 2 ) for special-purpose vehicles. The known connection is welded, and the welds do not withstand impact and abrasion as well as the rest of the material. To render the vicinity of the connection as resistant as the rest, the end of each strip is inserted in a matching aperture (4) in the frame component.
