Evaluation of the energy absorption and the damage on woven laminates subjeted to high-velocity impacts

Abstract

In this work, it was evaluated the behaviour of monolithic structures made of woven laminae of E-glass/polyester.subjected to high-velocity impacts, through experimental techniques. It were studied four monolithic laminates of different  thicknesses:3, 6, 9 and 12 mm, evaluating the energy absorption, the contact time between the plate and the projectile during the impact event and the extension of damaged area in both faces of the laminate, through non-destructive inspection techniques. Once the results were obtained, It was found that laminates of greater thickness show a larger damage area for both faces of laminate, greater contact time .and, minumun perforation-energy.
