Thick-walled laminates
In the research project ‘Cross-scale simulation and analysis of thermochemical phenomena during the curing of thick-walled thermoset fibre composite laminates’ (thick-walled laminates), the process-dependent material behaviour of thick-walled thermoset fibre composite plastics (FRP) with continuous fibre reinforcement during the curing and cooling process is to be analysed for the first time, taking into account the time- and spatially-resolved change in the degree of curing.
© IKVIn the project, the thermochemical phenomena and temperature equalization processes occurring inside the FRP are described in their entirety in order to develop an appropriate and efficient modelling and homogenization strategy for transferability to laminate and multilayer composites. The overall aim of the project is the realistic and cross-scale prediction of the temperature equalization processes occurring during the processing of thick-walled thermoset FRP, taking full account of cross-linking and temperature-dependent material characteristics. Based on validation tests, it will be shown that the developed macro-model can be used to precisely describe the temperature and degree of cure distribution in thick-walled laminates. By linking temperature equalization processes with thermochemical phenomena during the curing and cooling process, process understanding is to be substantially increased and a basis for targeted process design and optimization developed.
