    The present invention relates to a new transport pallet, which is particularly suitable for air traffic, wherein the same has substantially the shape of a square or rectangular plate and the same compared to the usual for this purpose plates based on aluminum or Aiuminiumlegierüngen significantly less weight or mass.
    There are already a variety of proposals for such transport pallets become known, in particular whose a yes not usable tare performing weight should be reduced as possible, which is particularly essential for aviation of essential importance.
    In the course of extensive tests, a new mechanically highly stable, high-strength pallet based on plastic material was developed. The new transport pallet is characterized in that it - for a substantial reduction in its weight - formed into substantial proportions with plastic material, - at least one - at least two crossing each other at an angle in the range of 15 to 90 °, at the respective crossing point, preferably over there Relativlagestabilisierungs gutters or notches for plug connection abutting, formed with a mechanically high-strength, fiber-reinforced composite plastic reinforcing struts or rods (-Strings, -Stringer), the same in a stable position and arrangement to each other holding, richly bound to them, and they comprise enclosing or embedding, preferably all-round, enclosing, formed with a plurality of sub-cores plate-like core of a mechanically stable foam plastic, - at which the reinforcing struts containing foam plastic core at least over the upper and lower main surface at least each because a mechanically high-strength layer is bonded from a fiber-reinforced composite plastic, or else which
    M multi-part foam core is encased in total by such a fiber-reinforced composite plastic layer, and - that is preferably provided that the side edges of the pallet plate either by in the local composite plastic material retracted, inserted, glued or incorporated, or possibly by are reinforced over the same drawn or inverted profiles made of aluminum or a high-strength aluminum alloy.
    The new range, which is thus formed to a high degree with plastic material having a density substantially close to 1 g / cm3, is characterized by the reinforcing struts provided inside, the hardened foam core and the hard composite surface - and -Unterschicht or -Ummantelung by high mechanical stability, high load capacity, high wear resistance and ease of handling and manufacturing.
    It is therefore of great interest for any type of transport, but especially for transport by aircraft, because they compared to the previously used in this field transport pallets based on aluminum with at least the same flexural strength and mechanical stability as the previously known pallets, a has up to 40% less weight.
    As regards the reinforcing struts of fiber-reinforced composite plastic present inside the new pallet, it has proved to be advantageous for the stability of the new pallet when the intersecting reinforcing struts or rods are substantially parallel or at an angle of 90 ° to the Side edges of the pallet plates or in the direction of the diagonal thereof are aligned.
    Particularly high mechanical quality of the new range can be achieved if the partial cores of the reinforcing struts containing or substantially enclosing foam plastic core at those of their side edges, where they rest against the reinforcing struts, to the cross-sectional shape of the same fitted cross-section having longitudinal recesses or Have flank grooves. 3/22 ϋ • • · · · · • t I I I I I I I t t t t t t t t t t t t t t t. * • • • • •: •: • • # • • ♦ · ♦ ·
    As far as the reinforcing struts themselves are concerned, it is advantageous if they have the same, possibly round, elliptical, square or hexagonal cross-section.
    However, a new transport pallet is particularly preferred, in which the reinforcing struts or rods have substantially (flat) strip-like design, very wide or flat I-section and that they are optionally provided with at least one indentation, notch or constriction.
    Reinforcing bars made of fiber-reinforced composite plastic have also proven to be particularly advantageous if necessary, which are formed approximately Torstahlartig.
    As regards the material of the reinforcing rods which is particularly preferred in the context of the invention, a particular advantage is given when the reinforcing struts or rods of the foamed plastic core contained in the same umbettet and the two outer layers or the sheath layer different or equal a formed with glass, carbon, aramid and / or mineral, especially basalt fibers reinforced composite plastic material is or is.
    For the foam core, which nevertheless contributes substantially to the strength of the new transport pallet, in particular as a consequence of the so-called sandwich effect, with the least possible mass, it has proved to be advantageous if the reinforcing strut or rod has several of its parts. Cores enclosing, foam plastic core with a mechanically stable foamed plastic, in particular with Rohacell or based on a polyurethane is formed.
    Last but not least, especially with regard to the rough loading conditions that prevail at airports, mentioned that it has proved to be beneficial if the side edges of the pallet or pallet plate on the top side edge-thickened or up-trained increases are, in that the Seitenrandverdickungen with the sheath layer of the fiber-reinforced composite plastic material are formed and at least one, preferably upwardly open undercut trough, in which a 4/22 *: ·· * ·: • ·

    Plastic-coated pallet plate is pushed or pulled sideways-thickening profile made of aluminum or an aluminum alloy, this profile is flush with the bottom composite resin layer on the bottom of the pallet,
    Here, the advantage of a substantial stabilization of the cargo through the raised edges is given, with an undercut trough profiling of the edges of the range is of particular advantage, in which, for example. the transport straps can be pulled.
    The invention is finally a method for producing the new transport pallets, which is characterized in that the intersecting reinforcing struts are made of the fiber-reinforced composite plastic, optionally via their connectors, in each desired mutual position, - that in the fields or, gusset between them and between them and the side edges of the pallet plate, the same corresponding shapes having partial cores made of a foamed plastic and positioned cross-sectional shape corresponding to the Armierungsstreben fitting and preferably ultimately glued to the reinforcing struts and so form a total of a reinforced foam plastic core, on which a plastic prepreg is applied for connection to the struts, - then at least on both sides of the foam plastic core each a Faserarmierungsvlies is applied, which after insertion of aluminum profiles on the Seitenr is impregnated with a change of the core polymer, and the structure is compressed so voprbereitete with introduction of polymer and the formation of the margin-umwulsteten pallet plate under the action of heat and pressure. 5/22 ·· ···· ·· ♦ ··· • · · · · · ·
