The present disclosure relates to a system for manufacturing a hybrid component including a first thermal supplier configured to heat a steel plate, a rolling roll for undercut configured to pressurize the steel plate heated by the first thermal supplier, and to form an undercut on one surface of the steel plate, a first molding roll configured to pressurize the steel plate formed with the undercut to mold the steel plate in a shape of a component to be manufactured, a composite material feeder configured to supply a composite material tape to be seated on one surface of the steel plate formed with the undercut through the first molding roll, and a composite material pressurization roll configured to pressurize the steel plate on which the composite material tape is seated.

Methods produce a folded connection, sealed by means of an adhesive composition and by means of first and second sheetlike elements, wherein a flange of the first sheetlike element, having a first surface (11) and a second surface (12), is taken back over a flange of the second sheetlike element. The methods apply at least one layer of an adhesive composition to the flange of the first sheetlike element, bead the flange of the first sheetlike element around the flange of the second sheetlike element, and apply the adhesive composition to both the first and second surfaces of the flange of the first sheetlike element.

An apparatus and method for fastening dissimilar metals like steel and aluminum utilizes a steel rivet and a spot welding machine. The rivet and metals are stacked and the heat from the welder's electric current softens the lower melting point aluminum allowing the rivet to penetrate the aluminum and weld to the steel layer. The fastener may be used to join stacks with several layers of different materials and may be used to apply a threaded socket or stud made from steel or titanium to an aluminum or magnesium alloy structure. Layers of non-conductive materials like plastic and ceramics may also be affixed to a conductive layer using the fastener made from a compatible material that extends through a pilot hole.

Disclosed is a structure for a hybrid-type door, which is capable of preventing deformation caused by difference in thermal expansion coefficient between an outer panel of aluminum alloy and an inner panel of iron steel. The structure for a hybrid-type door may include an inner panel and an outer panel made of different material from the inner panel. In particular, an end portion of the inner panel may be hemmed by an end portion of the outer panel with the end portions of the inner panel and the outer panel being brought into contact with each other. A sealer may be applied to a contact area at which the inner panel and the outer panel are brought into contact with each other, and the sealer may include a first sealer that may be curable at a room temperature, and a second sealer that may be curable at a temperature greater than a curing temperature of the first sealer.

The structure for a hybrid-type door may include an inner panel and an outer panel made of different material from the inner panel. In particular, an end portion of the inner panel and an end portion of the outer panel may be provided at a contact area, and the end portion of the inner panel may be hemmed by the end portion of the outer panel. A sealer may be applied to the contact areas at which the inner panel and the outer panel may be brought into contact with each other, and the contact area of the inner panel may include a non-contact space being free from contacting the sealer.

A motor vehicle includes a tailgate which has an inner panel, a reinforcing component and an outer panel. The inner component or the outer component is flanged on an end portion, forming a cavity or intermediate space. An adhesive is placed in the intermediate space. An end portion of the non-flanged component is arranged in the intermediate space. An intermediate space is formed between an inner surface of the inner component and an inner surface of the outer component and is filled with adhesive. The end portion of the middle component present in each case is arranged in the intermediate space.

The invention relates to a method of bonding panels together to form a panel assembly, comprising the following steps: providing a first panel (10) with a body portion (11) and an end portion (12) and a second panel (20) with a body portion (21) and an end portion (22); providing a first structural adhesive film (30) and a second structural adhesive film (31); applying the first structural adhesive film (30) on an upper side of the end portion (22) of the second panel (20) and applying the second structural adhesive film (31) on a lower side of the end portion (22) of the second panel (20); bringing the two panels (10 and 20) together and folding the end portion (12) of the first panel (10) around the end portion (22) of the second panel (10) such that the end portion (12) extends essentially parallel to the body portion (11) of the first panel (10) thereby enclosing the end portion (22) of the second panel and such that the first structural adhesive film (30) is positioned between the upper side of the end portion (22) of the second panel (20) and the end portion (12) of the first panel (10) and that the second structural adhesive film (31) is positioned between the lower side of the end portion (22) of the second panel (20) and the body portion (11) of the first panel (10); heating the assembly above the activation temperature of the first (10) and second structural adhesive tape (20); wherein the first structural adhesive film (10) differs from the second structural adhesive film (20).

A structural adhesive film is provided whereby both adhesion and edge coverage can be achieved. The structural adhesive film (1) includes a first curable resin layer (1a) containing a first thermosetting resin and a first foaming agent; and a second curable resin layer (1b) containing a second thermosetting resin. A curing temperature of the first curable resin layer (1a) is lower than a curing temperature of the second curable resin layer (1b); and a foaming starting temperature of the first foaming agent is lower than the curing temperature of the first curable resin layer (1a).

Surfaces 1, 2 are bonded together by a heat activated adhesive 3 that is applied to a surface 2 to cover an area greater than the area that is to form the bond, the two surfaces 1, 2 are brought together and the adhesive 3 activated so that it creates the bond and also covers the exposed edges of the surfaces to provide an aesthetically pleasing and coatable corrosion and rust protective layer.
