Abstract

UNA BOLSA DE VACIO UNITARIA (4) PARA LA FORMACION DE UN ARTICULOS COMPUESTO REFORZADO CON FIBRAS DENTRO DEL CUAL HAY MOLDEADO UN ELEMENTO DE DISTRIBUCION DE RESINA (10) CON LO QUE QUEDA FORMADO UN ARTICULO ESPECIFICO. LA BOLSA DE VACIO (4) SE FORMA SOBRE EL MOLDE QUE CONSTITUYE LA BASE PARA LA FABRICACION DEL ARTICULO COMPUESTO REFORZADO CON FIBRAS DESEADO. LA BOLSA (4) TIENE UN LADO ABIERTO, UN CONDUCTO DE DISTRIBUCION PRINCIPAL ELASTICO (10) QUE SE EXTIENDE LATERALMENTE A LO LARGO DE LOS EJES LARGOS DE LA BOLSA DE VACIO CON UNOS CONDUCTOS SECUNDARIOS (10) PARA PROPORCIONAR UN FLUJO DE RESINA DE LARGA DISTANCIA A TODAS LAS PARTES DEL ARTICULO COMPUESTO Y RECEPTACULOS TUBULARES ELASTOMERICOS (20). EN LA SUPERFICIE INTERIOR DE LA BOLSA HAY FORMADOS UNA PLURALIDAD DE CANALES TRANSVERSALES (14) A PARTIR DE UN PATRON DE PUNTOS (16) QUE CUBREN LA MAYOR PARTE DEL AREA BAJO LA QUE SE COLOCA LA ESTRUCTURA DE FIBRAS DENTRO DEL MOLDE. SOBRE EL MOLDE SE COLOCA UN MODELO PARA FORMAR UNA BOLSA DE VACIO(4) A PARTIR DE UN MATERIAL ELASTICO Y LA BOLSA DE VACIO SE UTILIZA PARA FORMAR UN ARTICULO COMPUESTO.
