Abstract

EN POLIMEROS CRISTALINOS LIQUIDOS SE DISPONE POR UNA PARTE DE CADENAS DE MOLECULAS RIGIDAS Y POR OTRA PARTE DE MODO AMPLIO DE SUSTANCIAS DE REFORZAMIENTO EN FORMA DE FIBRAS PRESENTES DE LA FORMA MAS AMPLIA POSIBLE EN DISPOSICION PARALELA CON RESPECTO A LA COSTURA DE FLUENCIA O DE ENLACE, CON LO CUAL FALLAN LAS PROPIEDADES FISICAS EN LA ZONA DE LA COSTURA DE FLUENCIA O ENLACE. ES OBJETIVO DE LA INVENCION CONSEGUIR UNA POSIBILIDAD, PARA IMPEDIR QUE PUEDAN GENERARSE DE FORMA PRINCIPAL LAS COSTURAS DE FLUENCIA O DE ENLACE. EL MATERIAL LICUADO SE APLICA POR ELLO ANTES DE LA ENTRADA EN EL MOLDE DE FUNDICION DE INYECCION CON UNA ENERGIA DE CORTE AL MENOS A TRAVES DE UNA PARTE DE LA LONGITUD DE LA PIEZA DE TRABAJO. ESTA ENERGIA DE CORTE SE GENERA POR MEDIO DE MOVIMIENTO RELATIVO ENTRE DOS SUPERFICIES DE LA PARTE DEL MOLDE.
