  4. Abstract:
  5. Fiber reinforced materials are widely used in many industrial structures including automotive, aviation, and civil due to their lower weights compared to metal structures. Full-composite body structures, especially in automotive and aviation applications, are becoming a proper replacement for current metal ones. For this reason, damage of such structures subjected to impact is a crucial case study in current research. The typical types of damages are mainly caused during production, repair, maintenance, or by particle crashes during function, and collisions between different structures. In this paper, four different fiber reinforced composite plates are studied after being impacted by a standard drop weight with different impact energies and moments. The damage zones are studied by ultra-sonic non-destructive inspection. Carbon fiber reinforced composite plates show the best structural behavior under low velocity impacts meanwhile carbon/glass fiber reinforced (hybrid) plates show suitable behavior under high impact energy. Finally, all the plates are modeled using ANSYS LS DYNA V6.1 under similar conditions to those of the tests. The damage zone shapes derived from software modeling do not show very good coincidence with those resulting from the tests. However, the software is able to predict the threshold of damage as it is verified well by test results. © 2005 Elsevier Ltd. All rights reserved
