Analytical modelling of high velocity impacts of cylindrical projectiles on carbon/epoxy laminates
8 pages, 15 figures.-- Special Issue: JNC 15 - 15èmes Journées Nationales sur les Composites (Marseille, France, Jun 6-8, 2007). ; In this work an analytical model has been developed in order to predict the residual velocity of a cylindrical steel projectile, after impacting into a woven carbon/epoxy thin laminate. 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. ; This research was done with the financial support of the University Carlos III of Madrid and of the Comunidad Autónoma de Madrid under Projects CCG08-UC3M/MAT-4464 and CCG08-UC3M/DPI-4348. ; Publicado
