Definitions
- the invention relates to sandwich elements with at least one predetermined breaking-point at which the sandwich element breaks in the event of an impact and also to their use in the automotive field.
- Sandwich elements can be employed, for example, in the automotive field as roof, bonnet, tailgate, door or floor-panel modules and also as load floors, rear parcel shelves or interior-trim components; an advantage in this connection is their high flexural rigidity with, at the same time, low area weight in comparison with structural elements of massive construction.
- structural elements that extend predominantly in a plane display high rigidity and strength values when loaded in that plane.
- these high strength values in the plane are disadvantageous.
- the present invention therefore provides constructional elements that exhibit, on the one hand, a low weight and, on the other hand, a high flexural rigidity and flexural strength and that, in addition, in the event of an accident (a crash, in particular a rear-end crash) do not transmit the energy of the crash into the passenger cell and hence endanger the occupants.
- the present invention provides a sandwich element with at least one predetermined breaking-point, the sandwich element made of
- a core layer preferably constructed from at least one ply
- At least one delamination means is included in at least a portion of the sandwich element on a first (tension) side of the sandwich element, and wherein the delamination means is disposed between the exterior layer located on the first (tension) side and the core layer or contained in the outermost third of the core layer on the first (tension) side of the sandwich element.
- the first (tension) side is that side of the sandwich element that is subjected to tensile stresses in the event of a flexural load.
- fibrous materials that are interspersed with plastics (such as, for example, polycarbonates, polyamides, polyurethanes, polyesters, polypropylene, polyethylene, polyvinyl chloride, polystyrene, polymethyl methacrylate, acrylonitrile/butadiene/styrene copolymers and blends thereof, epoxy resins, in particular polyurethane resin), such as glass-fiber mats, glass-fiber fleeces, glass-fiber random layers, glass-fiber cloth, cut or ground glass fibers and mineral fibers, natural-fiber mats, natural-fiber knitted fabric, cut natural fibers and also fibrous mats, fibrous fleeces and fibrous knitted fabric based on polymer fibers, carbon fibers or aramide fibers and also mixtures thereof.
- plastics such as, for example, polycarbonates, polyamides, polyurethanes, polyesters, polypropylene, polyethylene, polyvinyl chloride, polystyrene, polymethyl methacrylate, acrylonitrile
- Plastics such as, for example, polycarbonates, polyamides, polyurethanes, polyesters, polyethers, copolymers, polypropylene, polyethylene, polyvinyl chloride, polystyrene, polymethyl methacrylate, acrylonitrile/butadiene/styrene copolymers and blends thereof can also be employed.
- metal sheets, plastic sheets, wood panels or wood veneers can be employed. Glass-fiber mats with polyurethane resin applied to them preferably find application in the present invention.
- thermoformable and also thermosetting polyurethane and thermoplastic foamed materials paper honeycombs, metal honeycombs or plastic honeycombs with honeycomb or corrugated structure may preferably be employed in the present invention.
- a delamination means means having a decoupling effect (loosening the adhesion between exterior layer and core layer or weakening the core layer on the tension side), which are introduced either (a) in situ in the course of manufacture of the sandwich elements or (b) subsequently, may preferably be disposed between the exterior layers and the core layer.
- Suitable materials in case (a) include, but are not limited to, paper, cardboard, plastic foils and sheets or sheet-metal foils and plates, textile, plastic or metal foils provided with adhesive layers on one side, wood panels or wood veneers, impermeable textiles or naturally or synthetically based woven fabrics as well as solid or liquid films acting as separating agents as well as adhesive-free or coupling-agent-free zones.
- an adhesive-free zone for example, may act as delamination means.
- An adhesive-free zone or a zone with low adhesion or without adhesion can be produced by a delamination means which was inserted during the manufacture of the sandwich element being removed.
- Suitable in case (b) are subsequent, mechanical or thermal, locally limited separation, such as sawing, cutting, splitting or lasing, of the core layer and of the exterior layer on the tension side, so that a zone without adhesion is formed.
- the decoupling is more preferably obtained by means of delamination means that are described in case (a).
- the sandwich elements according to the present invention may find particular application in the automotive field as roof modules, bonnets, tailgate modules, door modules or floor-panel modules, more particularly as load floors, rear parcel shelves or interior-trim components.
- the flexural strength is the limit of the flexural load, the exceeding of which results in failure of the structural element.
- the flexural rigidity is the resistance of a structural element to flexure.
- Comparative Example 1 a compression test was carried out in the plane of the sheet (crash direction) on samples without predetermined breaking-point, and in Example 2, on samples with predetermined breaking-points according to the invention.
- Comparative Example 3 the flexural rigidity and flexural strength were determined on samples without predetermined breaking-point, and in Example 4, on samples with predetermined breaking-point according to the invention.
- Examples 5 and 6 show, on the basis of compression tests, how the breaking behavior can be controlled by modification of the type and geometry of the predetermined breaking-point according to the invention.
- Polyol 1 polyether polyol with an OH-value of 865, prepared by addition of propylene oxide onto trimethylolpropane as initiator.
- Polyol 2 polyether polyol with an OH-value of 1000, prepared by addition of propylene oxide onto trimethylolpropane as initiator.
- Polyol 3 polyether polyol with an OH-value of 42, prepared by addition of 86% propylene oxide and 14% ethylene oxide onto propylene glycol as initiator.
- Polyisocyanate polymeric MDI with an isocyanate content of 31.5 wt. % (DESMODUR 44V20L, Bayer AG).
- Stabilizer silicone stabilizer POLYURAX SR242, Osi Crompton Witco Specialities, Frankfurt.
- Catalyst amine catalyst THANCAT AN10, Air Products GmbH, Hattingen.
- Dyestuff BAYDUR Schwarzpaste DN, Bayer AG, Leverkusen.
- Polyurethane Formulation 1 Polyol 1 30 parts by weight Polyol 2 20 parts by weight Polyol 3 33 parts by weight catalyst 2.8 parts by weight stabilizer 1.3 parts by weight acetic acid 0.3 parts by weight dyestuff 3.3 parts by weight polyisocyanate 140 parts by weight
- the polyol mixture formed from Polyols 1 to 3 has an average OH-value of 568 mg KOH/g.
- the delamination means was cut to a width of 15 mm and a length of 1,000 mm and was stuck onto one side parallel to the course of the paper corrugations in the middle of the core layer. Then there were placed on both sides chopped glass-fiber mats having an area weight of 450 g/m 2 which were treated at room temperature by spraying on 450 g/m 2 of polyurethane formulation 1.
- This sandwich element was introduced into a flat tool heated to 130° C. and subsequently press-molded to a thickness of 19.4 mm.
- the tool was opened and the finished sandwich element was taken out.
- the size of this sandwich element amounted to about 1,000 mm ⁇ 1,000 mm.
- three rectangular samples with a size of 400 mm ⁇ 180 mm were sawn out of the sheet, the longer edge of the sample being at right angles to the course of the paper corrugations of the core layer.
- the samples were sawn out in such a way that the delamination means was located in the middle of the samples. With the exception of the delamination means, these samples were produced so as to be identical to those from Comparative Example 1.
