Modelling Laminated Fabric Composites under Impact Loads

Abstract eng:
A multiscale modelling approach for predicting impact damage in fabric reinforced laminated composites is presented. Thereby, the fabric topology of a multi-layered laminate is modelled at the level of individual tows for a sub-domain, which is embedded in a region with a homogenised representation of the laminate. This way, inherent effects arising from the fabric topology are accounted for. As an example, numerical simulations of a laminated plate in a drop tower impact test setup are conducted. The modelling approach is verified against experimental data, where very close agreement between the predictions and the experiments is found. The predicted energy absorption is compared to predictions of an equivalent ply-level model with a homogenised representation of the fabric plies, where significant differences in the energy contributions of individual mechanisms are observed. Furthermore, the effect of different weaving styles on the energy absorption of the laminate is investigated.
