The model is based in an energy balance, in which the kinetic projectile energy is absorbed by the laminate through three different mechanisms: linear momentum transfer, fiber failure and laminate crushing. This last mechanism needs the quantification of the through-thickness compressive strength, which has been evaluated by means of quasi-static punch tests. Finally, high velocity impact tests have been accomplished in a wide range of velocities, to validate the model.8engCFRPHigh speed impactEnergy balance equationconference proceedingsIngeniería Mecánicaopen access18DYMAT 2010 proceedings: dynamic mechanical behaviour of polymers and composites: 19th technical meeting, 2010, Strasbourg, FranceCC/0000012249
