The present research is aimed to investigate the properties of bond between fibre and cement-matrix on micro-scale and link the received information to characterise the adhesion and frictional slip. The environmental scanning electron microscope was utilised. The area of real contact between fibre and cement matrix was measured in longitudinal and cross-sectional directions. Critical shear stress required for the debonding process was calculated based on principles of contact mechanics. The results of this study will contribute into understanding of the mechanisms governing the debonding process and frictional slippage, which influence the behaviour of fibre reinforced composites under loading.
