A dynamic model of ceramic/fibre-reinforced plastic hybrid composites under projectile striking
A dynamic model of ballistic impact against ceramic/FRP (fibre-reinforced plastic) hybrid composites is presented in this paper. This model describes each status of the projectile and armour at different instants in the process of impact. Based on the Florence and low-velocity models, a three-phase impact theory is developed which forms a dynamic model. Equations are given for different impact phases to depict erosion, momentum and displacement of the projectile and target, which are then used by the computer to make calculations and simulations. Furthermore, the dynamic model has been checked to find agreement with ballistic tests. The dynamic model will be very helpful in the estimation of ballistic impact properties and optimum design of the ceramic/FRP hybrid composites.
