Abstract
In fibre reinforced brittle matrix composites the
mechanicalbehaviour of the interface between the fibres and the
matrix has avery significant influence on the overall mechanical
behaviour ofthe composite material. Since brittle matrix
composites are designed primarilywith the aim of improving the
strength and ductility of the brittlematrix material rather than
changing the overall stiffness,the ability of the fibres to
interact with cracking processes in thematrix material is
essential. Furthermore, since matrix cracking in afibre reinforced
material can only take place with simultaneousinterfacial
debonding of the fibre-matrix interface, it is clear thatspecial
emphasis should be put on the mechanical and strengthproperties of
the interface. The present paper gives an overview of the
different modelsapplied in the literature in the description of
interfaces incementitious composite materials. It covers the
geometricalcharacterisation, the mechanical characterisation of
the interface - including the perfectly bonded, the debonded and
the cohesiveinterface, the debonding criteria - including stress
based andfracture mechanical criteria, discussion and finally a
total of 97references.
