Abstract
Description
Die vorliegende Erfindung betrifft ein Sandwichmaterial mit einer Außenhaut aus Aluminiumblech, glasfaserverstärktem Kunststoff oder Holz, dadurch gekennzeichnet,The present invention relates to a sandwich material with an outer skin made of aluminium sheet, glass fibre reinforced plastic or wood, characterized in that
daß durch Einbringung eines Wabenaufbaus aus Papier die Steifigkeit ohne Einbringung spezieller Versteifungsvorrichtungen signifikant erhöht wird und das Material wasserfest ist.that by introducing a honeycomb structure made of paper, the rigidity is significantly increased without the need for special stiffening devices and the material is waterproof.
Allgemein besteht das Bestreben, den Nutzlastanteil eines Lastwagens zu maximieren.The general aim is to maximize the payload of a truck.
Der Zwang zur Minimierung des Eigengewichtes von Lastwagen und zugehörigen Aufbau wird dabei um so stärker, je geringer das zulässige Gesamtgewicht des Lastwagens ist.The pressure to minimize the dead weight of trucks and their bodies becomes greater the lower the permissible total weight of the truck is.
Dieser Zwang besteht ganz besonders bei den Lastwagen bis 7,49 to zuGG. Aber auch bei den schweren Lastwagen mit 16 to zGG und mehr wird die Wertschöpfung des Transportes durch ein niedriges Eigengewicht des Aufbaus erhöht.This requirement is particularly important for trucks with a GVW of up to 7.49 tonnes. But even for heavy trucks with a GVW of 16 tonnes and more, the added value of transport is increased by a low deadweight of the body.
Sandwichmaterialien, die im Stand der Technik als Material für Aufbauten von Lastwagen verwendet werden, bestehen beispielsweise aus Schaumstoff als Mittelschicht mit einer Deckschicht beidseits aus Holz und glasfaserverstärkten Kunststoff oder aus Schaummaterialien mit beidseits glasfaserverstärten Kunststoff.Sandwich materials that are used in the state of the art as material for truck bodies consist, for example, of foam as a middle layer with a covering layer on both sides made of wood and glass fiber reinforced plastic or of foam materials with glass fiber reinforced plastic on both sides.
Diese Materialien sind relativ teuer, schwer und haben eine schlechte Biegestabilität, so daß teilweise Verstärkungsprofile bei deren Produktion eingearbeitet werden müssen. Bei Beschädigungen der Außenhaut sind Reparaturen meist schlecht möglich und es müssen ganze Segmente ausgetauscht werden.These materials are relatively expensive, heavy and have poor bending stability, so that reinforcement profiles sometimes have to be incorporated into their production. If the outer skin is damaged, repairs are usually difficult and entire segments have to be replaced.
Es sind auch Sandwichmaterialien bekannt, deren Außenhaut aus Aluminium oder GfK und der Sandwichkern als Wabenkonstruktion aus Aluminium oder Gfk gefertigt sind.Sandwich materials are also known in which the outer skin is made of aluminum or GRP and the sandwich core is made as a honeycomb construction of aluminum or GRP.
Diese Sandwichaterialien haben eine sehr hohe Festigkeit und werden beispielsweise im Flugzeugbau eingesetzt. Der Preis dieser Materialien ist sehr hoch.These sandwich materials are very strong and are used in aircraft construction, for example. The price of these materials is very high.
Weiter bekannt sind Sandwichmaterialien mit einem Wabenkern aus Altpapier, die sich durch hohe Biegesteifigkeit, geringes Gewicht und günstigen Preis auszeichnen, wobei die Außenhaut vorzugsweise aus Aluminium besteht.Also well known are sandwich materials with a honeycomb core made of recycled paper, which are characterized by high flexural rigidity, low weight and low price, with the outer skin preferably made of aluminum.
Diese Materialien sind extrem wasserempfindlich, verlieren bei Feuchtigkeit ihre Stabilität und neigen zur Schimmelbildung oder verrotten leicht.These materials are extremely sensitive to water, lose their stability when exposed to moisture and tend to form mould or rot easily.
Im Fahrzeugbau werden bisher keine selbsttragenden Strukturen für den Tragrahmen eingesetzt.In vehicle construction, no self-supporting structures have been used for the supporting frame to date.
Dies erfordert einen erhöhten Aufwand für Stahl- und/oder Aluminiumkonstruktionen, die als tragendes Element den regulären Fußboden aufnehmen.This requires increased expenditure on steel and/or aluminum structures that support the regular floor as a load-bearing element.
Es wird die Aufgabe gelöst, im Fahrzeugbau durch den Einsatz von speziellen WabenkonstrktionenThe task is solved in vehicle construction by using special honeycomb constructions
• mit beidseitiger Beschichtung aus Aluminiumblech und/oder Kunststoff eine selbsttragende Struktur zu bilden die es ermöglicht, ganz auf den üblichen Tragrahmen zu verzichten, also selbsttragend zu• to form a self-supporting structure with a coating on both sides made of aluminium sheet and/or plastic, which makes it possible to completely dispense with the usual supporting frame, thus making it self-supporting
