We used a partial discrete FEA model based on a unidirectional composite consisting of a microscopic area of fibres and matrix surrounded by a homogenised composite area. The FEA provided information about the stress state in the matrix and the fibre-matrix interface. The transverse strength of the composite was calculated regarding matrix failure and fibre matrix debonding. The influence of the temperature on the Young's modulus, the non-linear stress-strain behaviour and the strength of the matrix were investigated in detail. Following this approach it was possible to incorporate the resulting micro-residual stresses on the transverse strength of the composite. Tensile tests of the neat resin and of the composite were performed in the temperature range of -40 °C to 60 °C. The results of the FEA modelling are in good agreement with the experimental results of the transverse tests. © VSP 2005.en0927-644020053-4379394Carbon fibreDebondingFinite element analysis (FEA)Matrix crackingResidual stressTransverse failureConference Paper10.1163/1568554053971560Other
