Abstract

Plaquette de plastique contenant des fibres de verre métal lisé. La plaquette a une âme en fibres disposées de façon à se disperser lors de la fabrication d'un objet en formant des fibres individualisées et des paquets de fibres parallèles entre elles et perpendiculaires au courant de plastique lors du remplissage d'un moule. Application à la fabrication d'articles thermoplastiques formant écran aux ondes radioélectriques et magnétiques.Plastic plate containing smooth metal glass fibers. The wafer has a core of fibers arranged so as to disperse during the manufacture of an article forming individualized fibers and bundles of fibers parallel to each other and perpendicular to the flow of plastic when filling a mold. Application to the manufacture of thermoplastic articles forming a screen against radioelectric and magnetic waves.
