Abstract

In the present study, mechanical characterization of composite materials used in marine applications is performed under blast loading of varying intensities. The significance of the study arises from the increasing attacks on naval structures due to various terrorist and war activities, employing explosive blasts. The composites used in the study are E-Glass reinforced vinyl ester composites and carbon composites. Rectangular panels of these composites fixed at all boundaries were subjected to a blast loading using explosives or shock wave generated by a shock tube. Attention focuses solely on the damage imparted by gaseous expansion from an explosion and the associated rapid release of energy on the composite targets. The dynamic strain response of these panels under varying shock magnitude was recorded in real time. Damage patterns and post impact deformation in the panels were also studied and are reported. Post impact dynamic compressive strength of these Carbon composite panels were also studied and are reported.
