Debonding Study of the Viscoelastic Laminate in Planning Hull Vessels Subjected to Slamming

This project is based on the investigation of one characteristic of a new material to improve GFRP high speed vessels constructions. The main objective is to find the debonding, that is the analyzed characteristic that is going to prove that the material works to avoid delamination in the bottom. This characteristic is studied by laboratory reproductions, by designing fiber glass specimens and modifying some of them with viscoelastic, to compare the modified and non-modified ones. The laboratory experiment is based on performing an axial force in the specimen until it separates. By analyzing the force and displacement obtained from the tensile tests, the crack growth rate and stress ratio for each specimen were evaluated. The failure ratio, which allows the evaluation of shear, was also performed.
