Abstract: Reinforcing a cement with a continuous structure of fibres (called textile reinforced cement) can lead to increased toughness and enhanced tensile strength of the composite. This is obtained through the initiation of multiple cracks within the matrix, and stress transfer between matrix and fibres. Amongst the proposed micromechanical models, the Stochastic Cracking Model is distinguished by a Weibull distribution function for matrix tensile strength and a frictional bond slip between fibres and matrix. A parameter study is performed, showing the influence of the model parameters, of the fibre volume fraction, and of the quality of fibre-matrix stress transfer on the obtained tensile composite behaviour, and on the development and widening of matrix cracks
