Definitions
- the invention relates to a double-layer sheet made of two a space between the cover plates that form, at least one cover plate as a knobbed plate trained and at the tips of his nubs with the other Cover plate is welded or soldered, and from one filling material filling the space from at least two different types of fabric.
- Double-layer sheets of this type are available in different Versions known (DE 195 03 166 A1; DE 196 06 981 A1; US-A 4,559,274; Stahl und Eisen 117 (1997), No. 10, page 46).
- Double-layer sheets are mainly used in Vehicle construction because of its high rigidity at relatively light weight and still in certain limits can be formed, especially deep-drawing, are.
- the characteristic thickness of the cover plates lies less than 1 mm, especially less than 0.5 mm, and that of Filling material between 1 and 5 mm.
- Filling material are different in the known double-layer sheets Materials, for example perforated mats, in particular made of plastic or cellulose, or perforated Aluminum sheets, inserted. With perforated mats or Aluminum sheets grip the knobs of the knobbed sheet through the holes in the mat.
- a double-layer sheet is known (US-A 4,559,274), whose cover plates are designed as double plates and on the Studs are welded together.
- Filling material made of two different substances, namely from a medium flexible layer of foam, jute, Metal wool or the like and outer layers from one synthetic foamable material.
- the double-layer sheet foams the foamable Material and completely fills the cavities.
- the invention is based on the object To create double-layer sheet of the type mentioned at the outset, that's a better ratio of area moment of inertia to Basis weight than the conventional one Double-layer sheets and not to fail due to buckling inclines.
- Double layer sheet of the type mentioned above solved that the behavior of the filler at Compression of the double-layer sheet by one Bending load by at least two in the direction perpendicular to Significant moduli of elasticity are marked in the sheet plane is, with the filling material Plastic as a matrix with particles embedded in it from one that determines the harder modulus of elasticity Material exists and the expansion of the particles in Direction perpendicular to the sheet plane 2% to 8% smaller than is the distance of the cover plates.
- the proportion of the filling material with the soft modulus of elasticity the bending line of the Double-layered sheet. If the bending force increases, then the proportion of the filling material with the harder Elastic modulus effective, which prevents the Closer cover plates and thereby the Moment of inertia of the double-layer sheet continues is reduced. Because the extension of the harder particles perpendicular to the sheet plane smaller than the distance of the Cover plates is at the beginning of the bending load Proportion of plastic in the filling material for determining the bending stiffness of the double-layer sheet, during the influence of the harder particles to bear comes when this after mutual approximation of the Cover plates due to increasing bending stress on it Plant come.
- the softer modulus of elasticity should be perpendicular to Sheet plane (Z direction) may be less than 50 MPa while the harder one is much larger than 50 MPa and much more should be less than 210,000 MPa. He should preferably at least 500, more preferably 1,500 MPa.
- a plastic is particularly suitable, whose modulus of elasticity in the Z direction is less than 20 MPa
- a plastic is preferably used in which dispersed plastic hollow spheres are distributed that at a medium temperature that is below temperature for full curing (crosslinking), melt.
- This is in particular a thermosetting one Material, because then the melting of the pore-forming hollow spheres are thermosetting Foam used as an intermediate layer in the double-layer sheet because of its dimensional stability a reshaping of the Double-layer sheet, especially deep drawing, without significant impairment of the rigidity of the Double layer sheet as a result of detachments and Cracks in the filler allowed and also Resistant to baking temperatures of up to approx. 220 ° C.
- the Invention provided that as a plastic matrix serving portion of the filler dispersed Contains plastic hollow beads with up to 70 vol%, by melting in the filling material of the finished Partially distributed, closed pores produce.
- the harder modulus of elasticity of the filling material is preferably determined by hard bodies in the Filling material with up to 10 vol% can be included or up to 5% of the weight of the double-layer sheet can be.
- the mutual distance of all Hard body in the sheet metal level should on average 3 to 7 times the distance between the cover plates.
- Hard bodies are those made of hollow glass spheres, Hollow ceramic balls or metal.
- Hard body made of glass or Ceramics can only be used if that Double-layer sheet need not be weldable for assembly, that is, no current bridge for one Resistance welding of the cover plates is required. in the otherwise you will use metallic hard bodies.
- the hard bodies should, however, have a lower hardness than the cover plates, so that they can Double-layer sheets do not damage the cover sheets.
- As Mold for the hard body are hollow bodies, such as Example curved chips, speckled grain, fragments of Metal foam, for example from cast potted Melting steel, or hollow aluminum powder.
- hollow bodies such as Example curved chips, speckled grain, fragments of Metal foam, for example from cast potted Melting steel, or hollow aluminum powder.
- sharp-edged metal hard bodies for example curved steel or aluminum chips Carry out assembly welding without any problems, because with the Resistance welding the metal hard body that Plastic, not yet hardened Filling material when compressing the cover sheets cut through and then an electrical contact bridge between the cover plates at the welding site.
- the filling material under heat to a tough state curing plastic can be used.
- a tough state curing plastic Preferably should complete curing (crosslinking) between 150 ° C and 230 ° C.
- the full curing in this Temperature range is advantageous in that Temperature range also the temperature for the branding of a varnish. Burning in the paint on the Double layer sheet and the full curing of the Plastic can then be done in one step.
- the double-layer sheet is to be formed, should the transformation between the partial and Full hardening of the plastic of the filling material take place because in the partially cured state the forming without affecting the moment of inertia can be done.
- the full curing can be done with epoxy resin be designed so that cracks and detachments heal.
- Applying the filler with deformable Hard bodies can be extruded or in the form of a perforated mat according to the knob distribution partially cured plastic.
- a plastic have thermosetting adhesives as more suitable than thermoplastic adhesive exposed.
- epoxy glue is beneficial because this glue one, albeit low electrical conductivity have, which ensures that at a electrostatic painting also the cut edges of the Accept double-layer sheet of lacquer.
- Embodiment shows on average Double-layer plate.
- the double-layer sheet consists of two spaces between the forming cover plates 1,2 made of galvanized Steel sheet with a thickness of less than each 0.5 mm, in particular 0.30 mm, and from one Intermediate filling material 3. While the a cover plate 1, which when used as a body panel the outer skin forms, is smooth, shows the other Cover plate 2 truncated cones 4 on the End faces 4a welded to the smooth cover plate 1 or are soldered. The height of the knobs 4 and thus the Distance d of the cover plates 1,2 is between 1 and 5 mm. The knobs 4 have a distance of 15 mm to 40 mm.
- the filler 3 consists of plastic, in particular an epoxy resin, a hardener, an accelerator and a hydrocarbon resin and serves as a matrix for various bodies embedded in it.
- the Plastic 3 is designed so that it is at room temperature or slightly elevated temperature incomplete and glassy and at elevated temperatures of approx. 170 ° C to 210 ° C cures completely (cross-linked) to a tough state.
- Such a plastic allows in the partially cured Condition of the forming, especially the deep drawing.
- On such plastic is glued to the cover plates 1,2, which increases the shear strength of the double-layer sheet and thus the shear stress on the double-layer sheet relieved on the welded end faces of the knobs 4 becomes.
- thermosetting Plastic made of thermoplastic or thermosetting Plastic up to a volume share of 70% embedded.
- A is used as the material for the hollow spheres Plastic used at medium temperatures of approx. 140 ° C melts.
- the hollow spheres then leave in the preferably thermosetting plastic closed cavities so that a thermoset foam is created.
- Hard bodies in the plastic filling material embedded in the same or different types.
- This Hard bodies preferably made of metal, can contain hollow spheres 6, Metal foam fragments 7, short curved metal chips 8 or so-called sputtering metal grain 9.
- these hard bodies are finished in 6-9 Component perpendicular to the plane of the double-layer sheet one smaller expansion than the distance d of the cover plates 1.2 to have.
- the individual hard bodies should be in the sheet metal plane a larger diameter than the distance d Cover plates have 1.2, while their distances in geometric mean in the sheet plane 3 to 7 times the distance d of the cover plates should be 1.2.
- the Sum of the two possible distances in the Z direction Hard body 6-9 to cover plates 1.2 should be 2% to 8% the distance of the cover plates 1.2 in the finished formed Component.
- the hard body at least 6-9 are sometimes sharp-edged to serve as a matrix Cut through filler 3 and before full curing the cover plates 1,2 in the paint baking device to be able to contact electrically.
- the hard body As particularly suitable has evolved from the manufacture and use of chips Die-cast aluminum exposed because it becomes one Break off the 3 ⁇ 4 circle (3 to 8 mm diameter) and are sufficiently sharp with chip thicknesses of 0.2 to 0.4 mm.
- the production of the double-layer sheet described takes place in such a way that with on the cover plate 2 knobs 4 facing the filling material 3 either by extrusion or in the form of a partially cured according to the distribution of the knobs 4 perforated mat is applied.
- the metal hard body 6-9 which for Example 1-3% of the weight of the entire double-layer sheet make up, have a larger diameter or height than the later distance d the Cover plates 1,2.
- the filling material is compared to the End faces 5 of the knobs 4 are applied somewhat exaggerated. Then the cover plate 1 is placed on the knobs pressurized and on the end faces 5 of the knobs welded, then completely up to the distance d pressurized to distribute the filling compound.
- double-layer sheet is to be formed to it for example in vehicle construction Forming, especially deep drawing, before full Curing after partial curing. That state is well suited for forming.
- vehicle construction Forming especially deep drawing
- full Curing after partial curing That state is well suited for forming.
- reshaping breakage and partial detachment of the intermediate layer of the cover layers take place, but this will Reversed the appearance because the Expand pores linearly by approx. 10% and that still Press adhesive mass onto the straps.
- Duroplastic foam produced during full curing Temperatures not exceeding 200 ° C for 20 minutes flows out, so that the paint when baking the paint is not damaged by dripping.
