RTM molding simulation for unidirectional fiber reinforced composite components considering local fiber orientation and fiber volume fraction
Mold filling simulations provide efficient methods to reduce the cycle times at resin transfer molding (RTM) by an optimized injection strategy. However, for a realistic modelling, it is necessary to consider the local fiber orientation and fiber volume fraction resulting from the draping process. This is possible by using a virtual process chain with different computer aided engineering (CAE) software. In this work an experimental method (microwave incineration) assists the CAE chain and so a more detailed consideration of the local fiber structure is possible. The present paper works out the advantages of using these methods for the molding simulation of a complexly shaped composite part. This approach competes with a state of the art model by comparing both models with experimental pressure measurements.
