Measuring the Thermal Conductivity and Effusivity of Automotive Components

Today’s automotive industry incorporates a wide range of materials into the construction of its vehicles. From composite interior paneling, to the rubber in the tires and everything in between, modern vehicle manufacturing incorporates an extensive range of components in even the simplest models. While there are an ample number of material performance properties to consider, thermal conductivity (k) and related thermal properties such as effusivity are of great importance to almost all areas in question.

High thermally conductive materials are critical for parts such as break pads and engine components that must dissipate heat. Newer hybrid and electric vehicles incorporate thermoelectric components that have very low thermal conductivities by design to aid in energy conversion efficiency. Automotive composites will often have anisotropic or orientation-dependent heat transfer properties. It is important to be able to characterize the effective heat transfer in distinguishing between the through-plane and in-plane orientations. With so many mechanical, structural and electrical components working in synergy, proper knowledge of thermal heat characteristics of a multitude of components is crucial to the overall performance and quality of the build.

Join Adam Harris, Managing Director and Arya Hakimian, Applications Specialist at C-Therm for a discussion on characterizing the thermal properties of various automotive components and how C-Therm is leading the industry in fast, accurate, and repeatable thermal property testing.
