Continuous-fibre-reinforced plastic products show shape distortions when they are released from the mould after forming at elevated temperatures. The residual stresses and the resulting spring-forward of a curved product can be modelled, but this requires the three-dimensional thermo-elastic properties of a laminate. These are predicted for a woven fabric reinforced plastic using micromechanics. To verify the modelling, a dilatometer test set-up is developed to measure the dimensional changes due to temperature changes of curved strip specimens made of carbon/PEI 5H satin weave fabric laminates.
