Abstract
(A1) Um ein Verfahren bereitzustellen, welches eine einfache und kostenguenstige Herstellung eines dreidimensionalen Strukturelements ermoeglicht, wird vorgeschlagen, dass ein Werkstoff des dreidimensionalen Strukturelements auf eine Formgebungseinrichtung zur Formung des dreidimensionalen Strukturelements gesprueht wird.

 

DE 102009018131 A1 UPAB: 20101125 NOVELTY - The method for producing a three-dimensional structural element (108), comprises spraying a material of the three-dimensional structural element onto a shaping device (102) for forming the three-dimensional structural element in a powdered manner. A shaping element (110) of the shaping device is moved, so that the production and/or the processing of the three-dimensional structural element is enabled in a continuous process and so that the three-dimensional structural element is produced and/or processed without deflection of a moving direction of the three-dimensional structural element. DETAILED DESCRIPTION - The method for producing a three-dimensional structural element (108), comprises spraying a material of the three-dimensional structural element onto a shaping device (102) for forming the three-dimensional structural element in a powdered manner. A shaping element (110) of the shaping device is moved, so that the production and/or the processing of the three-dimensional structural element is enabled in a continuous process and so that the three-dimensional structural element is produced and/or processed without deflection of a moving direction of the three-dimensional structural element, where two shaping elements are moved past in a production direction of the structural element. The material of the structural element is sprayed on a shaping roller, a roller strip and/or a negative mold (114) of the shaping device. The material sprayed on the shaping device is pressed using a press roller, roller strip and/or a positive mold of a pressing device (106), and is heated. A spraying device, by which the material is sprayed onto the shaping device, is moved relative to the shaping device. The component of the material of the structural element is a duroplastic, thermoplastic or elastomeric material, and is an adhesive material or resin, where the fibers and/or filler material are admixed to the material of the structural element for reinforcement and short fibers, glass fibers and natural fibers are selected as a part of the admixed fibers. The material of the structural element is partially sprayed onto the shaping device in a liquid manner. A covering layer is adhered, sprayed or pressed onto the structural element using a pressure roller. An intermediate layer is applied onto the structural element before the application of the covering layer. A non-woven material is selected as material of the intermediate layer. An INDEPENDENT CLAIM is included for a device for producing a three-dimensional structural element. USE - Method for producing a three-dimensional structural element. ADVANTAGE - The method ensures simple, rapid, continuous, easy and cost-effective production of the three-dimensional structural element with high stability in an effective manner.
