The Accurate Prediction Method of Tension Modulus for Nylon Cord/Rubber Composite Material

摘要

To study the change rule of tension modulus for nylon cord/rubber composite material, a accurate prediction method is provided. Firstly, the calculation method for relevant parameters for rubber material Mooney-Rivilin constitutive model is proposed, the amendment formula for cord tension modulus is derived. Secondly, based on composite material micromechanics, the accurate numerical model is built, the equivalent modulus is calculated and compared to the experiment results in reference. Finally, the accurate prediction formula of tension modulus for the nylon cord/rubber composite material is provided, compare the equivalent tension modulus obtained by the prediction formula and the numerical model. The results show that: the method to build the numerical model of nylon/cord-rubber composite material is correct, the prediction formula of the tension modulus for the nylon cord/rubber composite could predict the tension modulus well.
