Abstract
UN ELEMENTO DE BAJA DENSIDAD FORMADO POR UNA HEBRA TRIDIMENSIONAL (1) COMPUESTO DE DOS HOJAS DE TEJIDO CONECTADAS MUTUAMENTE MEDIANTE FILAMENTOS DISPUESTOS PERPENDICULARMENTE AL PLANO DE CONFIGURACION DE DICHAS HOJAS DE TEJIDO, ES IMPREGNADO CON RESINA, Y DESPUES DE HABER SIDO SOMETIDO A UN TRATAMIENTO DE PRE-DUREZA O PRECURA DE LA RESINA, ES INTRODUCIDO EN UN MOLDE (11) PARA EL CURADO FINAL DE LA RESINA. ENTRE LAS DOS HOJAS DE LA FIBRA TRIDIMENSIONAL EN EL MOLDE, SE SUMINISTRA UN FLUIDO PRESUTIZADO, ANTES DE LA CURA FINAL. LA HEBRA TRIDIMENSIONAL PUEDE SER RECUBIERTA ANTES DE SU INTRODUCCION EN EL MOLDE, CON DOS HOJAS EXTERIORES RESISTENTES DE TEJIDO IMPREGNADO CON RESINA.
