MetadataShow full item record
The insertion of a viscoelastic layer is proposed to mitigate damage by vertical impact. For this purpose, unmodified GFRP panels and others modified with the viscoelastic sheet are made. The results of measuring the acceleration, doing vertical impacts on the panels, are to obtain the acceleration, the critical points of damage by characterizing with fluorescent penetrating inks in ultraviolet light, and the analysis of results with equations that allow obtaining the absorbed energy. The benefits of the modification are evaluated and its protection to the laminate is checked.
