摘要 依据混合律,建立短纤维增强橡胶基密封复合材料纵向拉伸模量的理论预测模型,研究材料纵向拉伸模量随纤维长径比、体积含量以及温度变化的规律。结果表明:理论模型预测的纵向拉伸模量与试验结果较为一致;材料纵向拉伸模量与材料的诸多组分力学性能参数、细观结构参数以及温度有关;纵向拉伸模量随短纤维平均长径比和体积含量的增加而增加,随着温度的升高而减小。 Based on the mixture law theory, a model for predicting the longitudinal tensile modulus of short-fiber-reinforced rubber sealing composites was developed. The influences of the fiber aspect radio, fiber volume fraction and temperature on the longitudinal tensile modulus were investigated. Research indicates that the longitudinal tensile modulus predicted by the presented model is in good agreement with experimental data. The longitudinal tensile modulus is largely related to some microstructural parameters, mechanic performances of the main components of the composite and the temperature, it increases with the increase of average fiber aspect radio and fiber volume fraction, and decreases with increasing temperature.
