The Florences model hasfrequently been used to optimize the design of a two-component ceramic-faced lightweight armor against normal.But the the energy of formation and splashing of ceramic about 45%~70% of total energy were neglected in this model, together with the materials influencing factor.Therefore, the M-Florences model is deduced in this paper with introduction of the ceramic cone angle ψ, the function coefficient K of projectile and targe, and then modificated and optimizated the M-Florences model.The results showed that the ceramic cone angle ψ is directly related to the materials texture of two-component composite armor.When the backplane is Al, the ψ is 30°, and for the high strength steel, the ψ is 60°.As the ψ gets bigger, more reliable are the calculation results.The function coefficient K should directly reflect the influence of the materials and process of armor.Based on experimental measurments, the function coefficientare K1=0.9864 and K2=0.8754 corresponding to the 7.62mmAP and 12.7mmAP.The precision of M-Florenc1es model is improved 50% comparing with Florences model.
