          Abstract

          RESUMEN Para el diseño de embarcaciones construidas por laminados de GFRP se propone una inserción con capa viscoelástica para disminuir la propagación del daño producido por el impacto vertical del fondo de la nave con el mar o fenómeno de slamming. Mediante comparaciones de impactos verticales por caída de peso que reproducen la energía inferida al panel durante la navegación, se estudia la propagación del daño de paneles de preimpregnado curados OoA comparándolo con paneles modificados con inserción de capa viscoelástica. El empleo de lectura de datos de aceleraciones durante el impacto permite cuantificar mediante la formulación desarrollada los beneficios de la modificación observando el comportamiento de la fuerza, el desplazamiento y la energía que devuelve el panel luego del impacto y que no se convierte en daño intralaminar e interlaminar.

          ABSTRACT For the design of vessels built by GFRP laminates, an insert with a memory foam layer is proposed to reduce the spread of damage produced by the vertical impact of the ship's bottom with the sea or slamming phenomenon. Using vertical drops- weight impact machine that reproduces the energy inferred to the panel during navigation, the propagation of the damage of OoA cured prepreg panels is studied by comparing it with modified panels with insertion of viscoelastic layer. The use of acceleration data reading allows the benefits of viscoelastic modification during impact to be quantified through the developed formulation. The force, displacement, and energy returned by the panel after impact have also been quantified, which does not become intralaminar and interlaminar damage.
