In-Situ Strain Monitoring-Based Simulation of Residual Stress/Strain Due to Skin-Core Effect in
Thick CF/PPS Laminates

Abstract:
When a thick CFRTP laminate is manufactured by practical high-rate processing conditions with rapid heating/cooling, thermal skin-core effects are induced by non-uniform temperature distribution in the throughthickness direction, causing non-uniform residual stress/strain. There are only a limited number of reports about estimation of residual stress/strain development in rapidly cooled laminates because of the difficulty in determining material properties for the simulation and these results have not been sufficiently validated by experimental results. This current study demonstrates a high accurate residual stress/strain simulation under a rapid cooling condition based on in-situ strain measurement using optical fibre sensors and clarifies the development process and distribution amount of residual stress/strain in a thick UD CF/PPS due to thermal skincore effects. The simulation results are finally validated by experimentally-measured in-plane transverse strain.
