Important results from the project
The aim was to connect methods for prediction of stresses developed in composites structures during the entire manufacturing chain i.e. forming and cure. The goal was to describe the forming process influence on the fibre reinforcement, to improve the methods of predicting the final residual stresses built-in the composite structures, to develop measurement methods for strains/stresses in the material during manufacturing and use of project knowledge in industrial projects.
Expected long term effects
Material data for un-cured state is developed, by KTH and SICOMP, for forming and shape distortion. Saab and KTH has explored the wrinkle development process during forming and cure, which has resulted in 3 scientific papers and PhD examination. KTH, SICOMP and Saab has developed simulation methods incorporating forming and cure, which has been presented at Flygteknik 2016. CREO Dynamics has developed technology for measurement of strains during forming and residual stresses in cured laminates.
Approach and implementation
The Project has worked with both experimental and numerical methods. Equipment as well as knowledge at both industry and academy has been used. A close co-operation between the project partners including SME has been a necessary condition for the project results and the border crossers has therefore had great influence on the knowledge transfer. Thanks to the close co-operation the project has both resulted in knowledge use in industrial projects as well as academic credits and examination.
