Abstract
Abstract Plates of honeycomb structure, that are made, for example, from polyamide paper, are used as core material for sand-wich boards with covering layers of carbon or glass fibre rein-forced plastics or of aluminium. The new light-weight construction material is to be used for manufacturing honeycomb structures which, in comparison to the known honeycomb structures, are characterized by higher strength and stiffness, improved energy absorption and improved behavior in fire. The light-weight construction material consists of a fibrous thermoplastic compo-site foil which contains carbon, silicon carbide, whisker or the like fibres in the form of woven fabric, or mats, the fibres being embedded in a matrix of a high temperature thermoplastic such as polyether ether ketone, polyether sulfone or polysulfone.
The sandwich boards with honeycomb cores are used in the field of aeronautics and space travel, mechanical engineering, and in the construction of rail vehicles and watercraft as well as of sport and recreational equipment.

Description
~2S6~
The i~vention relates to light-weight construction material and to a process for manufacturing honeycomb structures from such light-weight construction material.
Plates of honeycomb structure, that are preferably manufactured from a high-strength polyamide paper and coated with a phenolic resin unaffected by high changes of temperature, are used as core material fox sandwich boards with covering layers of carbon or glass fibre reinforced plastics or of aluminium. Such sandwich boards are structural members with a very high strength 1~ and stiffness, a high specific energy absorption cap~city and good elasticity at the lowest weight. Sandwich boards with honeycomb cores are used in the fields of aeronautics and space travel, mechanical engineering and in -the construction of rail vehicles and watercraft as well as of sports and recreational equipment.
Light-weight building boards with a honeycomb structure are manufactured according to the "expansion process" or the "pro-filing process".
During the expansion process strip material, for ex-ample polyamide paper drawn from a reel is severed into sheets, an adhesive is dotted onto the sheets in straight lines running in the direction of travel of the strip, the sheets are stacked and the lines of adhesive are hardened. Finally the layers of paper stacked on top of one another are pulled or spread apart into honeycomb blocks Erom which plates with the desired thickness can be cut. Furthermore, it is possible ko cut discs of the desired thickness from the stack of sheets and to then spread : . : .
~: , ,, :
: . ,: . . .
,:, ' .~ '' : - ' ` :
~O~S6~3 these discs apart into plates o~ honeycomb structure.
The profiling process is used to manufacture honeycomb structures having greater strength. In this process the strip material, for example o~ aluminium, running off a reel, is rolled by means of profile reels into, for e~ample, a trapezoidal profile strip, the profiled strip is severed into trapezoidal profile plates, an adhesive is applied to the raised parts of the trape-zoidal profile plates and the plates are stacked on top of one another and glued together to form a honeycomb block from which paneling of desired thickness is cut.
It is the object of the present invention to develop a light-weight construction material as well as a process and in-..:
stallation for manufacturing honeycomb structures from this mate-- rial which, in comparison to the known honeycomb structures, areI characterized by a higher strength and stiffness, improved energyj absorption as well as improved behaviour in fire.
The light-weight construction material according to the present invention which meets these objectives consists of a fibrous thermoplastic composite foil which contains carbon, sili-con carbide, whisker or the like fibres in the form of woven fabric, nests or mats, the ibres being embedded in a matrix of a high temperature thermoplastic such as polyether ether ketone, polyether sulfone or polysulfone.
Three processes are proposed in accordance with the present invention for manufacturing honeycomb structures from fibrous thermoplastic composite foil described above, these ",' ' : ~
.,.,.~ , . .
~`::
'',,',: . . ~: "` ' ' '` ' processes using -the known "profiling pxocess" and being distin-yuished by the production of fibrous thermoplastic composite foil as the base material for the honeycomb structures.
In the first process an upper and a lower heated thermo-plastic foil strip and a fibrous material guided between the two foil strips are joined together by rolling.
The second process is characterized in that the thermo-plastic foil strip is extruded and subsequently joined to a fi-brous material by rolling.
The third process is characterized therein that thermoplastic granules are melted and in the melted state rolled with a fibrous material to a fibrous thermoplastic composite foil.
The latter process avoids the disadvantages occurring in the first two processes of poor fibre wetting and fibre damage caused by the high viscosi~y of the thermoplastic composite foil used.
In all three processes the fibrous thermoplastic com-posite ~oil is compressed following rolling by subsequently heat-ing and rolling it once or several times and is brought to the desired thickness.
Three installations operating according to the processes described abo~e are explained herebelow on the basis of the accom-panying schematic drawings, which show in Figure 1: a side view of a complete installation for manufacturing honeycomb structures, Figures 2 and 3: side ~iews of two modified parts I
