Composite carbon fibres with different embedment depth in concrete matrix and angle configuration were used to investigate single fibre pull-out behaviour. Composite carbon fibres were manufactured by impregnating carbon fibre filaments with epoxy resin. Composite carbon fibres with diameter 1.77 mm and 50 mm length were used with smooth outer surface. Composite fibre diameterwas obtained by changing the carbon filament number (from 8 k to 24 k carbon fibre filaments). The fibre filament number used in this investigation was 24 k. The composite concrete matrices with compressive strength 40, 75 and 120 MPa, and very good flow ability were used for pull-out samples. Fibres were embedded in the concrete matrix with depths from 5 to 25 mm and angles configured in 0, 30, 45 and 60 degrees to the pull-out force. Single fibre pull-out tests were performed and force-displacement diagrams were obtained. Single fibre pull-out performanceandfibre failure mode was analysed. Fibre peak pull-out force for smooth fibres shows a steady and linear increase with the fibre embedment depth increase. Fibres with smooth surface show high performance and resistance to pull-out, when configured in the angles to the pull-out force.
