    Abstract

    A parametric study was carried out to investigate the influence of various parameters on the overall thermoelastic constants and the local stress distributions in a unidirectional carbon-fibre epoxy. The study is based on micromechanical modelling by means of finite element analysis. The evaluation of the thermoelastic constants was found to be in very good agreement with analytical results. The main emphasis was placed on evaluating the local stress distribution and the magnitudes and locations of the maximum stress values in order to find the weakest point in the composite where initial failure is most likely to occur under transverse tension and axial shear loading. The results show that geometrical variations in the composite have a higher influence on the actual stresses in the composite than changes in the constituent properties.
