Abstract

Procedimiento para fabricar un brazo de material compuesto para estructuras modulares articuladas o telescópicas para la distribución de hormigón, que proporciona preparar un molde del tipo macho (11) que tiene una sección transversal provista de por lo menos una pared sustancialmente plana, la cual se reduce en por lo menos uno de sus tamaños y en por lo menos una parte longitudinal, pasando desde uno de sus extremos al otro y que comprende una primera fase de deposición en la cual una o más capas de fibra (16, 25) son distribuidas en la superficie exterior (17) de dicho molde de tipo macho (11), dichas fibras (16, 25) pueden estar o no impregnadas previamente con una matriz resinosa, y una segunda fase de extracción en la cual el molde macho (11) es expulsado del producto así obtenido, estando provisto un posible tratamiento térmico, por ejemplo en una autoclave, antes de la extracción del producto, caracterizado por que durante dicha primera fase de deposición está provista una distribución de dichas fibras (16, 25) con una concentración variable a lo largo de la extensión longitudinal de dicho molde macho (11).
