Description
Verfahren zum Herstellen von spezifisch leichten Körpern und nach dem Verfahren hergestellter Zellstruktur-Körper
Nach dem Patentanspruch I des Hauptpatentes ist ein Verfahren zur Herstellung von spezifisch leichten und wärmeisolierenden Körpern relativ hoher Eigenfestigkeit und Formstabilität auf der Basis von Schaumstoffmaterial, dadurch gekennzeichnet, dass eine lose Masse von rundlichen Schaumstoffkömem mit flüssiger, aushärtbarer Bindemittelmasse zur Oberflächenbe- netzung der Körner und anschliessend mit Feststoffpulver zur L7berdeckung der Bindemittel-Hüllschichten der Kömer vermischt wird,
dass die derart erhaltene lose Masse von rundlichen doppelt ummantelten Schaumstoffkömem in einer Pressform unter Einwirkung von Pressdruck und Aushärtung des Bindemittels zu einer Hohlzellstruktur mit verbundenen, ausgehärte- ten, polyedrischen Zellwänden und dem Material je eines ursprünglichen Schaumstoffkornes als Zellkammerinhalt verpresst wird.
Gemäss vorliegender Zusatzerfindung ist erfindungsgemäss vorgesehen, dass als Feststoff, welcher der Masse von rundlichen Schaumstoffkörnern nach erfolgter Oberflächenbenetzung derselben mit flüssiger, aushärtbarer Bindemittelmasse zur Ueberdeckung der Bindemittelhüllschichten der Kömer zugemischt wird, mindestens teilweise ein faseriges Material einer gegen über dem durchschnittlichen Durchmesser der Schaumstoffkugeln 1-4 mal grösseren Durchschnitts-Faserlänge benützt wird, um die Zugfestigkeit der erhaltenen Körper zu vergrössern.
Als Fasermaterial werden mit Vorteil geschnittene, lockere Glasfasern, aber z. B. auch Textilfasern, wie Cellulose-Kunstseide, Polyamid-oder Naturfasern mit Längen von ca. 3-10 mm bei Schaumstoffkömem von 1-3 mm Durchmesser verwendet. Selbstverständlich sind bei der Wahl des verwendeten Bindemittels und des Fasermaterials die Anforderungen an den erzeugten Zellstrukturkörper hinsichtlich Festigkeit, Wärme und Witterungsbeständigkeit vor allem an die Resistenz gegen Feuchtigkeitseinflüsse zu berücksichti- gen. Die besten Resultate werden mit Epoxyharz und Glasfasern erzielt. Dem Bindemittel kann zum Strekken auch pulveriges Material z. B. Quarz oder Kreidemehl zugemischt werden.
Dies sollte vor dem Zumischen des Bindemittels zu den Schaumstoffkugeln und nur in dem Masse geschehen, dass die Benetzungsfä- higkeit der Bindemittelmasse nicht wesentlich beein trächtigt wird. Die mit Fasern gründlich durchmischte Masse von bindemittelbenetzten Schaumstoffkörnem soll in Formen möglichst auf etwa einen Drittel bis die Hälfte der ursprünglichen Schichtdicken zusammengepresst werden, um ein inniges Einbetten der Fasern in das Bindemittel zu sichern. Auf diese Weise lassen sich Zellstrukturen erzeugen, deren Zugfestigkeit 30-40 kg/ cm2 bei einem Raumgewicht von 100-300 kg/m3 betragen kann.
Die Erfindung betrifft auch einen nach dem erfindungsgemäss verbesserten Verfahren hergestellten Zellstrukturpresskörper, der miteinander fest verbundene, aus erhärtetem Bindemittel und darin eingebettetem Feststoff aus Fasermaterial bestehende polyedrische Zellkammerwände aufweist, die je das Material eines Schaumstoffkornes enthalten.
Derartige Zellstrukturkörper, vorzugsweise Platten, können in Verbindung mit Deckschichten, aber auch ohne solche, Wand-, Decken-, Boden-und andere Fertigbauelemente für den Baubedarf, aber auch Stän- der und Gehäuse für den Maschinen-und Apparatebau und besonders Gehäuseteile für Luft-und Raumfahr zeuge bilden, also überall da Verwendung finden, wo hohe Festigkeit, bzw. Steifigkeit geringe Wärmeleitfä- higkeit, und hochliegende Eigenschwingungsfrequenzen zur Vermeidung von Deformationen unter dem Einfluss von Erschütterungen verlangt werden.

Process for the production of specifically light bodies and cell structure bodies produced by the process
According to claim I of the main patent, a process for the production of specifically light and heat-insulating bodies of relatively high inherent strength and dimensional stability on the basis of foam material, characterized in that a loose mass of round foam grains with liquid, hardenable binding agent for surface wetting of the grains and is then mixed with solid powder to cover the binding agent coating layers of the grains,
that the loose mass of round, double-coated foam grains obtained in this way is pressed in a mold under the action of pressure and hardening of the binding agent to form a hollow cell structure with connected, hardened, polyhedral cell walls and the material of an original foam grain as the cell chamber content.
According to the present additional invention it is provided according to the invention that the solid, which is added to the mass of round foam grains after the surface has been wetted with liquid, curable binder material to cover the binder envelope layers of the grains, is at least partially a fibrous material of a size compared to the average diameter of the foam balls 1- 4 times the average fiber length is used to increase the tensile strength of the body obtained.
As fiber material, cut, loose glass fibers, but z. B. textile fibers such as cellulose rayon, polyamide or natural fibers with lengths of approx. 3-10 mm are used in foam grains of 1-3 mm diameter. Of course, when choosing the binder and fiber material used, the requirements placed on the cell structure body produced in terms of strength, heat and weather resistance, especially resistance to moisture, must be taken into account. The best results are achieved with epoxy resin and glass fibers. The binder can also be powdered material for stretching. B. quartz or chalk flour are added.
This should be done before the binder is mixed with the foam balls and only to the extent that the wetting ability of the binder mass is not significantly impaired. The mass of binder-wetted foam granules, thoroughly mixed with fibers, should be compressed in molds to about a third to half of the original layer thickness, if possible, in order to ensure that the fibers are intimately embedded in the binder. In this way, cell structures can be created whose tensile strength can be 30-40 kg / cm2 with a density of 100-300 kg / m3.
The invention also relates to a cell structure pressed body produced according to the improved method according to the invention, which has polyhedral cell chamber walls made of hardened binding agent and solid fiber material embedded therein, firmly connected to one another and each containing the material of a foam grain.
Such cell structure bodies, preferably panels, can be used in conjunction with cover layers, but also without them, wall, ceiling, floor and other prefabricated structural elements for building needs, but also stands and housings for machine and apparatus construction and especially housing parts for air -and space vehicles, so they are used wherever high strength or rigidity, low thermal conductivity, and high natural vibration frequencies are required to avoid deformations under the influence of vibrations.
