Abstract

PROCEDIMIENTO PARA OBTENER UNA ESTRUCTURA DE RESINA REFORZADA RESISTENTE A LOS IMPACTOS. CONSISTE EN DISPONER DE MANERA ORDENADA SOBRE UN TROQUEL MACHO UNA ARMADURA TEXTIL REFORZADA (B), CONSTITUIDA POR UNA PLURALIDAD DE CAPAS DE TEJIDO EN FORMA DE MALLA TENSADA, SUPERPUESTAS Y SEPARADAS ENTRE SI, DE TAL MANERA QUE LOS BORDES DE LAS CITADAS MALLAS ESTEN ANCLADAS AL TROQUEL. A CONTINUACION SE RECUBRE EL TROQUEL MACHO ASI PREPARADO CON EL TROQUEL HEMBRA Y SE PROCEDE AL LLENADO DE LA CAVIDAD COMUN MEDIANTE INYECCION DE RESINA TERMOPLASTICA Y TERMORRESISTENTE DE POLICARBONATOS. LA ARMADURA TEXTIL PUEDE ESTAR HECHA DE FIBRAS NATURALES, ARTIFICIALES O SINTETICAS E INCLUSO DE FIBRAS DE VIDRIO. EL PROCEDIMIENTO ADMITE VARIANTES DE FORMA Y REALIZACION. DE USO EN LA REALIZACION DE REVESTIMIENTOS PROTECTORES Y EN ESPECIAL EN LA FABRICACION DE CASCOS PARA UTILIZACION DEPORTIVA Y LABORAL.
