Abstract

The invention relates to the manufacture of an earth screen based on glass or carbon or aramid ("Kevlar", registered trademark of Dupont de Nemours) fibres combined with epoxy and/or polyester resins 1, 3, 5, 7. The earth-screen, deicing, drying, and cooling functions are all assembled into a compact product; however, each may be used individually. The product is particularly intended for telecommunication and satellite-television antennas. A simplified variant is used for the HF screening of electronics on board aircraft, spacecraft or ships. The chemical characteristics of the polyester allow, by this method, the manufacture of a mean-temperature thermal enclosure which can be flush-cleaned with water for the food and chemical industries.

Description

L'invention apporte une solution à la tabrication des écrans de terre, à la protection des appareillages éleotroniques embarqués (Aviation, Aérospatiale, Marine) contre les champs électromagnétiques et les agents atmosphériques corrosifs pour une faible masse. The invention provides a solution to the tabrication of earth screens, to the protection of on-board electronic devices (Aviation, Aerospace, Marine) against electromagnetic fields and corrosive atmospheric agents for a low mass.

L'utilisation des matériaux composites tel que les fibres, verre, aramide (XEVLAR marque déposée Dupont de
Nemours) et carbone associées aux résines, epoxyde et ou polyester (1-3-5-7) est déterminée par : la faible densité, la résistance mécanique, la tenue aux agents chimiques, la facilité de mise en oeuvre. De plus la facilité d'inclure dans les matériaux composites des éléments très légers donc fragiles, confère à ces derniers des caractéristiques mécaniques égales ou supérieures aux méthodes conventionnelles.The use of composite materials such as fibers, glass, aramid (XEVLAR registered trademark Dupont de
Nemours) and carbon associated with resins, epoxy and or polyester (1-3-5-7) is determined by: low density, mechanical resistance, resistance to chemical agents, ease of implementation. In addition, the ease of including very light and therefore fragile elements in the composite materials, gives the latter mechanical properties equal to or greater than conventional methods.

L'écran de terre (2) est obtenu par pistollage d'un vernis électro-conducteur pouvant recevoir un dépôt métallisant par galvano plastie ou électrolyse. Mais aussi par métal tissé ou en feuille. Le réseau de chauffage (4) est obtenu de la même manière avec toutefois une variante par inclusion d'un ruban électro-conducteur chauffant. Les vernis électro-conducteurs n'ayant pas de propriété d'aocrochage sur le support sont particulièrement adaptés. The earth screen (2) is obtained by spraying an electrically conductive varnish which can receive a metallizing deposit by galvano plasty or electrolysis. But also by woven or sheet metal. The heating network (4) is obtained in the same way with, however, a variant by the inclusion of an electrically conductive heating tape. Electro-conductive varnishes which do not have a fastening property on the support are particularly suitable.

Le réseau réfrigérant (6) est obtenu par inclusion d'un tube de cuivre en réseau assurant la circulation d'un fluide réfrigérant ou chauffant.The refrigerant network (6) is obtained by inclusion of a networked copper tube ensuring the circulation of a refrigerant or heating fluid.

Chaque zone étant intégralement isolée de ses voisines électriquement et chimiquement on peut les utiliser simultanément. Each zone being completely isolated from its neighbors electrically and chemically, they can be used simultaneously.

Particulièrement destiné aux antennes de télécommunication et pouvant travailler dans des conditions extrêmes, l'utilisation de réseau individuellezent trouve d'autre application industrielle. Particularly intended for telecommunication antennas and being able to work in extreme conditions, the use of individual network finds other industrial application.

Ex : Cavité résonnante UH écran électromagnétique allégé (1-2-3) Enceinte thermique moyenne et basse température (34-5) et ou (5-6-7) ainsi que les réservoirs à pré-chauffage. Ex: Resonant cavity UH lightened electromagnetic screen (1-2-3) Medium and low temperature thermal enclosure (34-5) and or (5-6-7) as well as pre-heating tanks.

Tous les procédés de stratification pouvant être utilisés. Des pièces de formes diverses peuvent etre fabriquées de l'unité à la série.  All the stratification processes that can be used. Parts of various shapes can be manufactured from unit to series.
