Experimental Data

The research improves the mechanical properties of laminates in ship hulls made of glass fiber reinforced plastics (GFRP) with the design of auxetic sheets, to take advantage of the property in their geometry of reducing the damage energy due to surface impacts absorbed by the laminate. Using 3D printing of the second generation auxetic component for the production of modified specimens. Laboratory reproductions of mechanical damage are compared with specimens extracted from a ship under construction. It is obtained that the mechanical properties of Bending and traction allow us to demonstrate that the insertion of the core in the laminate protects the matrix from damage energy, prolonging its useful life. Comparative results are presented which will allow GFRP hull designers to insert auxetic sheet cores into their designs. The mechanical tests carried out allow us to compare how the delamination’s progress while.
