Measurements of rock thermal conductivity with a Transient Divided Bar. [EN]

Authors of the publication: - V Pasquale - Verdoya M - Chiozzi P

An apparatus (Transient Divided Bar - TDB) was implemented to determine the thermal conductivity of rocks. TDB consists of a stack of elements, which comprise a rock specimen placed between two copper blocks of cylindrical shape with known thermal capacity, initially kept at room temperature.

Ultra high thermal conductivity polymer composites[EN]

Authors of the publication: - YM Chen - JM Ting

Epoxy composites based on vapor grown carbon fiber (VGCF) were fabricated and analyzed for room temperature thermophysical properties. An unprecedented high thermal conductivity of 695 W/m K for polymer matrix composites was obtained. The densities of all the composites are lower than 1.5 g/cc.
