Influence of Interfacial Contact Resistance on Thermal Conductivity of Composites
In the preceding chapters, the thermal contact resistance between the filler particles and the matrix was neglected. The temperatures were assumed to be continuous across the filler-matrix interfaces. Thermal contact resistance arises in situations where there is poor adherence between the particles and the matrix [1-7]. Also, when the coefficients of thermal expansion of dispersed phase and matrix are significantly different from each other, voids or gap may develop between the two phases resulting in contact resistance.
