Definitions
- the invention relates to a composite material for the production of material plates of interconnected, preferably glued materials.
- a multi-layered material plate in which a middle layer consists of whole or longitudinally split bamboo tubes or bamboo chips or chippings.
- the tensile strength of the bamboo fibers improves the load capacity of the material panels.
- the invention has for its object to create a material plate, which further improves the reinforcement of material plates with bamboo.
- the inventive material plate has a greater number of advantages of the known material plates.
- material plate consists of a matrix 1 with embedded in these bundles 2 made of bamboo fibers.
- the matrix 1 consists of a composite material such as a homogeneous mixture of fillers, such as wood fibers, wood shavings, wood chips, etc., with glue.
- the composite material corresponds to the known wood fiber, chip OSB-etc. Plates.
- glue is understood in this description to mean any type of adhesive used for the bonding of such boards.
- the bamboo fiber bundles 2 consist of longitudinal, i. in the fiber direction, slashed or peeled leaves into elongated chips, which are combined into bundles and glued together to form strands.
- the strands may have different cross-sectional shapes, e.g. rectangular, circular, oval, flat etc.
- the strands in particular those with flat cross sections, can also be combined into mats, a crosswise arrangement being particularly advantageous.
- the production is carried out so that the bamboo fiber strands between two fiber strands of fibers and glue run into a press or are inserted and the layers are pressed together. This will be the material of the Cover layer partially pressed into the spaces between the bamboo fiber strands.
- the bamboo fiber bundles can be glued directly instead of previously glued. without prior gluing to run between the matrix layers in the press, so to speak "wet on wet", so that the bamboo fibers of the bamboo fiber bundles are glued together miteinender by the glue content in the matrix.
- bamboo fiber bundles act as reinforcement of the material plate.
- the bamboo fiber bundles can be placed either in the midplane of the panels or asymmetrically near the surface where the greatest tensile forces occur. It is also possible to arrange bamboo fibers in two areas close to the surface, so that the finished boards can absorb higher tensile forces on the sides.
Abstract
Der Verbundwerkstoff zur Herstellung von Werkstoffplatten besteht aus einer Matrix aus einem homogenen Gemisch aus Füllstoffen und Leim und in die Matrix eingebetteten Strängen aus miteinander verleimten Bambusfasern.The composite material for the production of material panels consists of a matrix of a homogeneous mixture of fillers and glue and embedded in the matrix strands of glued together bamboo fibers.
Description
Die Erfindung betrifft einen Verbundwerkstoff zur Herstellung von Werkstoffplatten aus miteinander verbundenen, vorzugsweise verleimten Materialien.The invention relates to a composite material for the production of material plates of interconnected, preferably glued materials.
Diese Werkstoffplatten aus einem Materialverbund ersetzen in den meisten Einsatzgebieten das früher ausschliesslich verwendete Vollholz aufgrund von mehreren vorteilhaften Eigenschaften, wie z.B. höhere Formstabilität, bessere Verarbeitbarkeit, niedrigere Kosten. Allerdings gibt es bis heute keine Werkstoffplatte, die alle Vorteile der bekannten Werkstoffplatten in sich vereinigt.These material panels made of a material composite replace in most applications the previously exclusively used solid wood due to several advantageous properties, such as. higher dimensional stability, better processability, lower costs. However, to date there is no material plate that combines all the advantages of the known material plates in itself.

Der Erfindung liegt die Aufgabe zugrunde, eine Werkstoffplatte zu kreieren, welche die Verstärkung von Werkstoffplatten mit Bambus weiter verbessert.The invention has for its object to create a material plate, which further improves the reinforcement of material plates with bamboo.
Erfindungsgemäss wird dies erreicht eine Werkstoffplatte mit den kennzeichnenden Merkmalen des Anspruchs 1.According to the invention this is achieved a material plate having the characterizing features of claim 1.
Die erfindungsgemässe Werkstoffplatte weist eine grössere Zahl von Vorteilen der bekannten Werkstoffplatten auf.The inventive material plate has a greater number of advantages of the known material plates.

Die in
Die Bambusfaserbündel 2 bestehen aus längs, d.h. in Faserrichtung, zu langgestreckten Spänen zerschlitzten oder abgeschälten Blättern, die zu Bündeln zusammengefasst und miteinander zu Strängen verleimt sind. Die Stränge können unterschiedliche Querschnittsformen besitzen, z.B. rechteckig, kreisförmig, oval, flach etc.The
Die Stränge, insbesondere solche mit flachen Querschnitten können auch zu Matten kombiniert werden, wobei eine kreuzweise Anordnung besonders vorteilhaft ist.The strands, in particular those with flat cross sections, can also be combined into mats, a crosswise arrangement being particularly advantageous.
Die Herstellung erfolgt so, dass die Bambusfaserstränge zwischen zwei Faservliessträngen aus Fasern und Leim in eine Presse einlaufen oder eingelegt werden und die Schichten miteinander verpresst werden. Dadurch wird das Material der Deckschicht teilweise in die Zwischenräume zwischen den Bambusfasersträngen gepresst.The production is carried out so that the bamboo fiber strands between two fiber strands of fibers and glue run into a press or are inserted and the layers are pressed together. This will be the material of the Cover layer partially pressed into the spaces between the bamboo fiber strands.
Alternativ ist es auch möglich, die Bambusfaserbündel, anstatt sie vorher zu verleimen, direkt, d.h. ohne vorherige Verleimung, zwischen den Matrixschichten in die Presse einlaufen zu lassen, also gewissermassen "nass in nass", so dass die Bambusfasern der Bambusfaserbündel durch den Leimanteil in der Matrix miteinender verleimt werden.Alternatively, it is also possible for the bamboo fiber bundles to be glued directly instead of previously glued. without prior gluing to run between the matrix layers in the press, so to speak "wet on wet", so that the bamboo fibers of the bamboo fiber bundles are glued together miteinender by the glue content in the matrix.
Es können auch Deckschichten aus Vollholz (Furnier), anderen einschichtigen Werkstoffplatten, wie Z.B. Holzfaserplatten, mehrschichtigen Werkstoffplatten, wie z.B. Sperrholz, Multiplex etc., Kunststoff, wie z.B. Melaminharz, Phenolherz etc. oder aus Metall, wie z.B. Aluminium, etc. verwendet werden. Weitere Deckschichten können auch auf die Faserschichten aufgebracht werden.It can also cover layers of solid wood (veneer), other single-layer material plates, such as. Wood fiberboards, multilayer material boards, e.g. Plywood, multiplex, etc., plastic, e.g. Melamine resin, phenolic heart etc. or metal such as e.g. Aluminum, etc. are used. Other cover layers can also be applied to the fiber layers.
Infolge der hohen Zugfestigkeit der Bambusfasern in Längsrichtung besitzen diese Platten einen besonders hohen Widerstand gegen Durchbiegung. Die Bambusfaserbündel wirken als Bewehrung der Werkstoffplatte.Due to the high tensile strength of the bamboo fibers in the longitudinal direction, these plates have a particularly high resistance to deflection. The bamboo fiber bundles act as reinforcement of the material plate.
Die Bambusfaserbündel können entweder im Bereich der Mittelebene der Platten angeordnet werden oder asymmetrisch in der Nähe der Oberfläche an der die grössten Zugkräfte auftreten. Es können auch Bambusfasern in zwei oberflächennahen Bereichen angeordnet werden, so dass die fertigen Platten auf Seiten höhere Zugkräfte aufnehmen können.The bamboo fiber bundles can be placed either in the midplane of the panels or asymmetrically near the surface where the greatest tensile forces occur. It is also possible to arrange bamboo fibers in two areas close to the surface, so that the finished boards can absorb higher tensile forces on the sides.
