|Summary||The purpose of this work is to show how the use of Inverse Gas Chromatography technique can be employed for predicting fibre-matrix adhesion in composites. This technique allows to determine different physical-chemical properties of the solid surfaces which can be combined for knowing the interaction that exists between fibres and matrices in composites. This technique can be employed in the zero coverage region and in the finite coverage region and also the distribution of active sites existing on the solid surface can be determined. Different values of the physical-chemical properties are given for different materials, and finally we show a good correlation between these properties and some mechanical properties of composites. However further work must be carried out in this subject in order to achieve a more complete knowledge of any type of material used for obtaining composites.
