Abstract

Procedimiento para reforzar con una resina estratificada armada una pieza constituida esencialmente por un casco termoformado, caracterizado porque consiste en sostener una cara del casco con ayuda de un cojín de materia elásticamente deformable que se adapta inicialmente a dicha cara, en colocar cerca de la otra cara un elemento de molde con superficie de trabajo elásticamente deformable o no y de forma complementaria, dispuesto de manera que forma un espacio libre entre el elemento y el casco, en inyectar bajo presión una resina de refuerzo en dicho espacio libre y en desmoldear el casco así reforzado.
