Description

Plate-shaped composite element, especially for cladding, cladding and the like.

The subject of the present invention is a plate-shaped Composite element, especially for cladding, cladding and the like.

There are currently known various types of composite plate-shaped members, usually by joining a central, resin-soaked mushroom made of synthetic fibers with a pair of outer layers made of fabric or non-woven fabric are obtained.

The layer element produced in this way is subjected to pressing processes in order to obtain the polymerization of the resin and making a composite member having acceptable mechanical strength properties.

However, the currently available known composite elements have serious disadvantages, among which the The first is that they are very deficient from the mechanical point of view, since the middle class, even when impregnated with resin, it is unable to impart suitable strength properties.

The solution of increasing the amount of resin so that the rigidity of the intermediate layer is increased has turned out to be Proven to be impractical, since the excessive impregnation with resin inevitably leads to a change in the same the outside of the skin layers, creating resin stains on the outside surface, and of course the product made themselves unacceptable.

Another disadvantage is further comprised as & iii ^ that the known composites! enierite not Wärra ^ formungsvörgange suitable are _i such that their Anvrendungmo'glichkeit is limited in different industrial areas *

The object of the present invention is to eliminate the disadvantages mentioned above by creating a plate-shaped composite element * that has the disadvantage of resin migration from the main layer to the outer layers does not have, although it has sufficient mechanical Has strength properties.

A particular object of the invention resides in the Creation of a plate-shaped composite element which is excellent for thermoforming processes is suitable, the field of application of which is considerably expanded.

Another object of the present invention is in the production of a panel-shaped composite element in which the intermediate layer is made from an "arsenic" product, which therefore has a very limited effect on costs of the finished product, making the same thing is made very competitive from a purely economic point of view.

They will * be solved or * achieved with a plate-shaped connecting elementί in particular for cladding ₄ cladding and the likej the invention is characterized in that it has an intermediate layer j which is made of natural fibers which are impregnated with a heat-meltable resin ₄ whereby the outer sides of this intermediate layer made of woven or non-woven fabric are associated with outer layers which are connected to the intermediate layer by a process which enables the polymerisation of the resin, which is present in an amount suitable to prevent its migration through the outer layers has caused.

The invention is explained in more detail below with reference to the exemplary embodiments shown in the drawing. Show it:

There are outer layers on both sides of the intermediate layer attached, both labeled 3 ΊΟ and made of a fabric layer or a Fleece layer or other materials that may be considered suitable can be produced.

The permanent connection between the outer layers 3 and the intermediate layer 2 is made by means of a pressing process carried out, the polymerization with subsequent hardening of the intermediate layer 2 impregnating Polyester resin caused so that the intermediate layer itself experiences a certain rigidity, ctie the panel-shaped composite element valuable imparts mechanical properties.

The proportioning of the polyester resins can be carried out in a relatively small amount, since the resins are excellent together with the Eokos fibers, and suitable mechanical properties are imparted to the assembly as a whole. - \

This fact is extremely important because the synthetic resins, after they are present in a small amount, have no possibility during the pressing process towards the outsides of the outer layers 3

Furthermore, according to the innovation for Warmfonnungsvorgäoge suitable, so that it "wallowing." of the eressing process is possible, is ^ the plate-shaped To give composite element directly the desired shape.

In this way the composite element can be used for the production of cladding and cladding e.g. in a car interior as well as for the production of vc-n interior cladding panels j small ceilings, lower rear surfaces or support surfaces or any type of cladding for both civil and civilian use can be used in a great many other commercial areas.

Furthermore, the presence of the coconut fibers, which i ~ In fact, after impregnation with the synthetic resin, a continuous row of internal spaces form, the composite element according to the innovation excellent sound-absorbing and sound-absorbing Properties.

For these reasons, the composite element is excellent as a cladding element for partition walls or, as a cladding element for the engine compartment from Wall separating the car interior.

From the above it can be seen how the Iseuerung achieves the stated objectives, with particular emphasis on the fact that the use of an intermediate layer made of natural carbon fibers enables the panel element itself to have improved properties compared to the known panel elements and, furthermore, considerably lend lower cost za.
