采用分子动力学方法，计算交联度92％的环氧树脂的力学性能参数，并比较不同温度下，环氧树脂力学性能参数的改变。研究结果表明，分子动力学模拟结果与试验结果相吻合。模拟结果显示，随着温度升高，交联环氧树脂的弹性模量、剪切模量和体积模量等性能下降，温度高于玻璃温度之后，环氧树脂力学性能下降显著。

Molecular dynamics methods were adopted to calculate the mechanical property parame-ters of epoxy rexin with a conversion degree of 92%.The changes of the mechanical property para-meters of the epoxy resin under different temperatures were compared.The simulation results were in agreement with the test results.The simulation results indicate that with the increase of the tempera-ture,the mechnical properties’paremeters of Young’s modulus,shear modulus and bulk modulus decrease with the properties being significantly lowered when the temperature was higher than that of glass.
