摘要

在这项工作中，引入了一个新的补充公式来修改 Kerner 模型。该补充公式通过对增强材料的热膨胀系数、体积模量和剪切模量进行归一化处理，使 Kerner 模型能够预测多相增强复合材料的热膨胀系数。为了进行比较，使用修正的 Kerner 模型以及修正的 Schapery、混合物规则和 Turner 模型预测了 6092 铝合金/碳化硅/β-桉石多相增强复合材料的热膨胀系数。结果证实了修正的 Kerner 模型在预测多相近球形夹杂物复合材料热膨胀系数方面的稳健性。

A Modified Kerner Model to Predict the Thermal Expansion Coefficient of Multi-Phase Reinforced Composites Al6092/SiC/LAS

in this work, a new supplementary formula was introduced to modify the Kerner model. This supplementary formula enable the Kerner model to predict the thermal expansion coefficient of multi-phase reinforced composites by normalization of the thermal expansion coefficient, bulk modulus, and shear modulus of the reinforcements. For comparison, the modified Kerner model as well as modified Schapery, the rule of mixtures, and Turner models were used to predict the thermal expansion coefficient of multi-phase reinforced composites 6092 Aluminum Alloy/silicon carbide/β-eucryptite. The results confirm the robustness of the modified Kerner model for predicting the thermal expansion coefficient of composites with multi-phase near-spherical inclusions. it may provide a fine selection to predict the thermal expansion coefficient of multi-phase reinforced metal matrix composites which cannot predict efficiently before.
