Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a multilayer planar reinforcement characterized in that it consists of a hard layer with a plasticizable and/or plastic layer on at least one side. The plastic layer preferably consists of a melt adhesive layer. In a preferred embodiment, it is sound-absorbing in the cured state.

This plasticizable and/or plastic layer can be thermoplastic or thermoset.

In one preferred embodiment, a slurry-like dispersion is used as the magnetic layer, which dries and/or reticulates under the action of heat. It is advantageous to use materials as plastic layers that harden on drying under the influence of heat.

According to a further advantageous embodiment, it is possible to use as the plastic layer a material that crystallizes under the action of heat or after heat treatment and, upon its dehardening, forms a strong bond with the plate to be reinforced.

According to a further advantageous embodiment, it is possible to use a material that "dries and crystallizes at the same time" as the plastic layer.

The plasticizable and/or plastic layer can have adhesive properties. According to another embodiment, a sound absorbing layer is provided on one side of the hard layer #i'.

According to another common implementation, the hard layer is a shaded plate,
In particular, it is constructed as a corrugated sheet.

In that case, the corrugated sheet can be provided with at least one layer which is in tangential contact with and firmly connected to the crests of the 1" waves.

Furthermore, the two axillary plates can be crossed and overlapped to form a strong connection at the contact point.

The top of the wave on the same double corrugated plate in history! At least one layer can be provided that contacts the 11th object and is firmly bonded to the top.

According to a further advantageous embodiment, the %hard layer can have a nest-of-peaks structure. Furthermore, it can be made of synthetic resin - hard 7 ohm.

The plasticizable and/or plastic layer may have acoustic properties.

The reinforcing body according to the invention can further be characterized in that on both sides of the reinforcing layer sound absorbing layers having a sound absorption loss rate are provided.

The reinforcement according to the invention can furthermore have an additional adhesive layer on one side of the plasticizable and/or plastic layer. This adhesive layer is then optionally a heat-sealable adhesive layer. Furthermore, a pressure-sensitive adhesive layer can also be used as the adhesive layer.

In the past, this reinforcement was often achieved by providing shaped @ in the thin plate. However, this is often not possible for aesthetic and/or aerodynamic reasons. Furthermore, the thin plate is gold IF
4! Reinforcement with IlI reinforcement was also performed. This reinforcement was blast-welded in the form of a lip onto the thin plate to be reinforced. However, this was an expensive process and needed to be saved. Attempts have also been made to reinforce thin plates with composite resin composites. For this purpose, the synthetic resin was applied to the thin plate in a softened state under heating. However, there is a drawback that the synthetic resin does not have the desired rigidity at normal temperatures.

There is a need for improved reinforcement for reinforcing thin sheets. Particularly in the automobile industry, there is a trend towards increasingly thinner sheet metals, especially for car bodies. However, such sheets must be reinforced.

The object of the invention is to develop a rigid reinforcement, in particular in the form of reinforcing ribs made of sheet metal, which can be provided on the sheet metal to be reinforced without requiring any special working steps.

This problem is solved according to the invention by providing a plastic and/or plastic layer on at least one side of the hard layer. As the hard layer, for example, the well-known Kinkaede Lip #A
I guess. The reinforcing body according to the invention is laid on the thin plate to be reinforced in such a way that its plasticizable and/or plastic layer is in contact with the thin plate. This is done before the reinforced sheet is passed through the lacquer drying RT. Next is the picture that passed the same drying F meeting.

The 'IIIJ plastic and/or /l'i plastic layers soften and bond with the reinforced sheet metal. After cooling the reinforcement according to the invention.

To be integrally connected to a thin plate to be reinforced without requiring a special work process for fixing the legs. The plasticizability and/or layer properties are particularly suited to the unbalanced properties of the plate to be refinished under the action of heat, thus making it a replenishing layer and retaining a high degree of temperature. Therefore thl! It is not necessary that the material layer conform exactly to the shape of the sheet to be reinforced.

Materials for the low wti-forming and/or /Ii plastic layers include:
Particularly when heat is applied to plastics, dry at an increased rate.

Dispersion-based pastes that reticulate, thermosets that harden at elevated temperatures, further dry under the action of heat and/or
Also suitable are slurry-like mixtures which crystallize to form bonds with high mechanical strength.

The sound-absorbing effect of the reinforcement according to the invention can be further increased by providing an additional sound-absorbing layer on the other side of the reinforcement.

Examples of embodiments of the present invention are shown in FIGS. 1 to 5 FIA.

In FIG. 1, a corrugated hard layer 1 is superimposed on a layer 2 of melt adhesive. After passing through the drying oven, the same molten adhesive layer 2
is bonded onto the reinforced thin layer 1[3.

In Figures 1 and 2, the corrugated hard layer 1 is additionally reinforced with an upper reinforcing plate 4 and a lower reinforcing plate 5). A molten adhesive layer 2, which is integrally bonded to the #ih reinforced thin plate 3, is bonded to the lower reinforcing plate 5.

A reinforcing hard layer 8 is provided on top of the adhesive layer 2, which in this case can have, for example, a honeycomb structure consisting of chambers 9 of hexagonal cross section. The thickness of the hard layer 8 is, for example, 10 mm. As the material for this hard layer 8, aluminum foil or aluminum sheet can advantageously be used.
