Abstract

LA INVENCION CONSISTE EN UN DISPOSITIVO PARA CONFORMAR UNA ESTRUCTURA PORTANTE MEDIANTE EFECTOS ELECTRICOS O MAGNETICOS. DICHA ESTRUCTURA PORTANTE SE COMPONE DE UN COMPUESTO DE FIBRAS COMBINADO CON UN MATERIAL DE BALASTO, Y DE CERAMICAS O POLIMEROS PIEZOELECTRICOS, CERAMICAS ELECTROESTRICTIVAS O MATERIALES MAGNETOESTRICTIVOS, COMO POR EJEMPLO LA ALEACION TERFENOL-D, DISPUESTOS EN EL COMPUESTO DE FIBRAS. DICHO COMPUESTO DE FIBRAS SE COMPONE DE UN GRAN NUMERO DE FIBRAS DISPUESTAS EN UN ANGULO (MAS MENOS) AL} CON RESPECTO A LA DIRECCION TRANSVERSAL X DE LA ESTRUCTURA PORTANTE, DE MANERA QUE LAS CERAMICAS O POLIMEROS PIEZOELECTRICOS, CERAMICAS ELECTROESTRICTIVAS O MATERIALES MAGNETOESTRICTIVOS, COMO POR EJEMPLO LA ALEACION TERFENOL-D, SE HAN APLICADO SOBRE LA ESTRUCTURA EN FORMA DE TIRAS DISPUESTAS EN LA DIRECCION TRANSVERSAL X.
