The work looks at the dynamic behaviour of laminated carbon-epoxy (C-E) composites with inserted interleaf material. Instrumented impact tests were performed to study the impact response of C-E system containing the interleaved PTFE-coated fabric material. Significant differences were noticed in the trend of the load-time plots. It was inferred that the introduction of small amounts of less adherent layers of material at specific locations causes a decrement in the load carrying capability of this material. An attempt to correlate these trends with the post impact observed failure features has been made in this work.
