摘要：

This work compares the impact resistance enhancement available through modifications to the interlaminar region of carbon fibre epoxy composites. Interleaving and short fibre interlaminar reinforcement techniques were used to improve the impact resistance of [0/90](5) laminates tested using a Dynatup 8250 instrumented impact tester. Visual observation was also employed to assess the affects of the interlaminar reinforcement whilst quantifiable assessment compared incident and restitutive energies to determine energy absorbed during the impact event. The results confirmed that when short fibres are used to interlaminarly reinforce the laminates, lower quantities of incident energy are absorbed than when laminates are interleaved or remain unreinforced. Visual inspection however showed damaged areas to be smallest in interleaved specimens, followed by short fibre reinforced and unreinforced laminates. (C) 2002 Elsevier Science Ltd.
