A New Polymer Matrix Composite Material System with a High Thermal Conductivity

为了提高聚合物基复合材料的导热性能，提出了一种包含金属包覆纤维和金属包覆微球的模型。为了准确评估该材料体系的导热系数，将基于热丝导热系数法建立微力学模型。该模型的性能将通过采用有限元方法的数字仿真研究进行评估。进一步的评估将通过实验进行，通过测量材料在不同方向的导热系数，使用热丝导热法。

In an attempt to increase the thermal conductivity of polymer matrix composites, a model which includes metal- coated fibers and metal-coated microspheres, is proposed. To accurately evaluate the thermal conductivity of this material system, a micro-mechanic model will be developed based on the hot wire thermal conductivity method. The performance of the model will be assessed through digital simulation studies by employing the finite element method. Further evaluation will be performed experimentally by measuring the thermal conductivities of the material in different directions, using the hot wire thermal conductivity method.
