The accurate prediction method for nylon/cord-rubber composite lamina was provided. Firstly,the calculation method for Mooney-Rivilin model relevant parameters of the cord-rubber material was proposed,the modified formula of tension modulus for nylon was derived. Secondly,based on micromechanics,the numerical model of nylon/cord-rubber composite material was built,the equivalent modulus was calculated and verified by the experiment. Finally,the accurate prediction method for nylon/cord-rubber composite lamina was provided,the equivalent modulus obtained by the prediction formula and the numerical model was compared. The results show that the method for building the numerical model of nylon/cord-rubber composite material is correct,the prediction formula of the tension modulus for nylon/cord-rubber composite lamina can predict the tension modulus well. The research method can provide technical support for the design of nylon/cord-rubber composite material.
