The dynamic response of freestanding carbon fiber reinforced composite sandwich plates with square honeycomb cores of different relative densities subjected to water blast is investigated by numerical simulations. The constitutive models are validated by quasi-static compression response comparisons of numerical simulations and theoretical calculations. The deformation process, core compression and momentum transmitting characteristics are analyzed and the regulations of the core compression and momentum transmitting for sandwich plates with different core relative densities are revealed. Dynamic response and protection property of composite sandwich plates and mass-equal laminate plates are compared, which indicates that the composite sandwich plates can provide superior protection from water blast than laminate plates.
