Abstract

METODO DE MOLDEAR MATERIALES PARA DARLES FORMA ONDULADA Y METODO DE BOBINAR FILAMENTOS, EN QUE SE DEPOSITA EN UN MOLDE UNA CAPA DE BASE DE HOJAS DE TELA IMPREGNADAS POR UN MATERIAL DE LIGADO. SE COLOCA UNA PLURALIDAD DE MACHOS HUECOS SEPARADOS PARALELOS, SOBRE LA CAPA DE BASE. LUEGO SE COLOCA UNA CAPA SUPERPUESTA SOBRE LOS MACHOS Y LA CAPA DE BASE, ESTANDO IMPREGNADA TAMBIEN LA CAPA SUPERPUESTA POR MATERIAL DE LIGADO. SE SOMETE EL CONJUNTO A CALOR Y TEMPERATURA. LUEGO SE SOMETE EL MACHO A UNA TEMPERATURA QUE PROVOCA SU ENCOGIMIENTO Y PERMITE SU RETIRADA. EL RESULTADO ES UNA CAPA DE BASE A LA QUE ESTA LIGADA LA CAPA SUPERPUESTA, PRESENTANDO LA CAPA SUPERPUESTA ONDULACIONES QUE AUMENTAN LA RESISTENCIA ESTRUCTURAL. EL FILAMENTO IMPREGNADO SE BOBINA ALREDEDOR DEL MOLDE.
