Definitions
- the invention relates to a method for producing a core structure, preferably for a core composite, (defined in DIN 53 290 Feb. 1982), the core structure consisting of a thin foldable starting material with an undefined length, in particular semi-finished fiber webs, pre-impregnated semi-finished fiber products, paper webs, cardboard webs, film webs , Sheet metal or the like is produced, wherein the starting material is folded into a spatial, multi-surface, developable structure, and wherein the starting material undergoes a contraction of the material web in the width and longitudinal direction and an expansion into space with respect to the expansion of the starting material and between the two outer surfaces of the core composite forming cover layers can be arranged and connected to the cover layers by gluing or other connection.
- the invention also relates to a device for carrying out the method, in particular for producing the core structure.
- core composites of the type mentioned at the outset, for example the corrugations in conventional corrugated cardboard or so-called honeycombs.
- core composites are required as light panels or shell elements for walls or floors in commercial aircraft, cars, ships or trains; also in the interior and exterior construction of buildings or in the furniture industry as a filler for veneered furniture or as in the case of corrugated cardboard also as packaging material.
- Structures of the type mentioned at the beginning can also be used as elements in filters, (fuel cell) reactors, solar collectors, design elements such as lamps, transparent elements, cladding elements or the like, as well as (crash) energy-absorbing, sound or radar-absorbing elements or as kinematics be used.
- the invention is based on the object of creating a method for producing a core structure in which the starting material is not stretched or compressed, but is instead - without making incisions or punched-outs - continuously folded according to area and angle.
- the object is achieved in that the material web is pretreated in a continuous process from the top and bottom along curved or several straight folding lines touching in a star shape and folding lines running in repeating patterns or within the areas which are delimited by the folding lines so that folding edges that allow kinking are created, which fulfill a function comparable to hinges and form the folding kinematics, that after pretreatment has taken place, the folding process is initiated in the area of the folding lines or the areas delimited by the fold lines are carried out on the upper side and the lower side of the material web, that the material web is delayed after initiation in order to complete the folding process, and that the material web can be post-treated to stabilize the folding structure after the folding process What can be done by, for example, the influence of temperature, embossing, impregnation, coating or the application of an open or closed top layer on at least one side of the folding structure formed.
- Embodiments of the method according to the invention are described in subclaims 2 to 8.
- sagging materials such as, for example, fabrics that would not in themselves form folding kinematics
- a synthetic resin can first be pre-hardened (bi-staging) and only fully hardened after the folding process has been completed, that the folding process along the pretreated folding lines is initiated by a suitable device
- the material itself being pretreated as folding kinematics serves that the thin starting material from its two-dimensional starting form with folding edges running at predetermined angles to each other or along curves undergoes an angle and area-accurate transformation during a folding process, that the core structure along the folding edges changes from its two-dimensional starting form into one in the third Dimension-extending core structure is folded, the core structure undergoes both a length and a width change compared to the two
- the core structures produced by the method according to the invention are advantageously characterized by their low density with simultaneous, in particular in cooperation with applied top layers, high bending and compressive rigidity and strength, and due to the folded structure and possibly the folded material, good sound insulation, which is achieved by perforation of the Cover layers can still be raised from.
- Another The advantage of the invention lies in the substantially increased production speed, which thus leads to a cost reduction, which is made possible by the continuous production.
- the possibility of folding the starting materials along curved folded edges also improves the compressive rigidity and thus expands the area of application of the core structures significantly compared to existing core structures, because structures folded along curved folded edges, unlike those that are only folded along straight folded edges, can be curved and are stiffer.
- the curved fold edges lie along their entire fold edge on the upper and lower cover layers, and can thus advantageously be glued to the cover layers with their entire fold line or otherwise connected.
