PROCEDE POUR LA FABRICATION D'UNE STRUCTURE ALVEOLAIRE A BASE DE MATIERE PLASTIQUE |
摘要 |
A plastic-based cellular structure is manufactured by continuously extruding parallel lamellae of a composition based on thermoplastic polymer(s) from amorphous or semi-crystalline polymers; subjecting the spaces between two adjacent lamellae to an injection of a fluid and to a vacuum to produce deformation of the lamellae and to weld them in pairs with formation of a cellular structure whose constituent cells extend perpendicular to the extrusion direction; and drawing the cellular structure perpendicular to the extrusion direction. |
