Abstract: In this paper, the Etr response of a series of Hi-Nicalon (SiC) fibre reinforced silicon nitride matrix composites is studied. At first, the processing route of the material is briefly described. Axial and transverse tensile mechanical behaviour, along with matrix crack density measurements , are then shown. Characterisation of the interface properties and evaluation of thermal residual stresses, obtained by modelling of axial hysterisis loops are finally presented. This is followed by a short description of a micromechanical model for the Etr response UD- CMCs. To conclude, experimental and theoretical transverse strain evolution are compared and discussed.
