Abstract

PREFORMAS DISTINTAS SON REALIZADAS PARA DIFERENTES PARTES DE UNA PIEZA, DE MATERIAL COMPUESTO A FABRICAR, Y SON ENSAMBLADAS EN UN ESTADO NO DENSIFICADO O NO COMPLETAMENTE DENSIFICADO, POR ENLACE ENTRE SUPERFICIES RESPECTIVAS EN CONTACTO CON LAS PREFORMAS (13, 15, 36) POR MEDIO DE FIBRILLAS (17, 19) QUE HACEN SALIENTE PERPENDICULARMENTE A LA SUPERFICIE DE UNA PREFORMA (13, 15) Y EN LAS CUALES SE TRASLADA LA SUPERFICIE DE OTRA PREFORMA (36). LAS PREFORMAS ENSAMBLADAS SON A CONTINUACION CODENSIFICADAS. LA FIBRILLAS ESTAN FORMADAS EN LA SUPERFICIE DE UNA PREFORMA FIBROSA POR LOS EXTREMOS DE FIBRAS DE ESTA, DESPLAZADOS POR AGUJEREADO DE LA PREFORMA. EL PROCESO ES CONVENIENTE EN PARTICULAR PARA LA FABRICACION DE UN PANEL SANDWICH DE MATERIAL COMPUESTO QUE COMPRENDE DOS PIELES RIGIDAS ENTRE LAS CUALES ESTA DISPUESTO UN ALMA FORMADO POR TABIQUES PERPENDICULARES A LAS PIELES.
