Different methods to evaluate SEA in GFRP laminated plates

Abstract The necessity of weight reduction in vehicle has brought nowadays, new and innovative materials that are able to replace traditional materials. For these reasons, the R&D world, especially composite materials for automotive applications, became important for that components which must ensure both lightness and high mechanical property. The research presented in this paper is based on drop-weight impact tests of GFRP (Glass Fiber Reinforced Plastics) laminated plate (Epoxy resin matrix reinforced with E-Glass Twill woven) at LVI (Low Velocity Impact). The tests have been carried out at different impact velocity (1.5 m/s and 6 m/s) to understand the strain rate effects. The Specific Energy Absorption, or SEA, has been evaluated after the test
