Abstract
Muelle de ballesta, fabricado de un material de resina sintética reforzado con fibra, caracterizado porque comprende una primera y una segunda capas de fibras cuya mayoría se orientan para quedar en el sentido longitudinal del muelle, y un elemento separador de fibras orientadas de una forma aleatoria entremedias al menos en la parte central de la longitud del muelle, para separar la primera y la segunda capas una de la otra en la dirección de flexión del muelle, incorporándose todas las fibras en una matiz de resina sintética.
