The effect of interleaving on the interlaminar fracture behaviour of unidirectional and woven-fabric fibre composites based upon continuous carbon fibres (CF) and poly(ether ether ketone) (PEEK) has been investigated over a wide range of temperature and crack speed. The fracture data obtained from mode I and mode II tests have been analyzed using the time-temperature equivalence postulate and the results are discussed in terms of fracture micromechanisms. The insertion of a resin-rich layer between laminae was found to increase significantly the fracture resistance of the composites, without altering its dependence on crack speed.

Abstract

The effect of interleaving on the interlaminar fracture behaviour of unidirectional and woven-fabric fibre composites based upon continuous carbon fibres (CF) and poly(ether ether ketone) (PEEK) has been investigated over a wide range of temperature and crack speed. The fracture data obtained from mode I and mode II tests have been analyzed using the time-temperature equivalence postulate and the results are discussed in terms of fracture micromechanisms. The insertion of a resin-rich layer between laminae was found to increase significantly the fracture resistance of the composites, without altering its dependence on crack speed.
