Effect of HIPing on the effective thermal conductivity/diffusivity and the interfacial thermal conductance of uniaxial SiC fibrereinforced RBSN

Composite Materials

“…It can be seen that the effect of interfacial conductivity is governed by the magnitude of non-dimensional parameter, k f / ah.. h, will have a value of infinity for perfect thermal contact and it will be equal to zero for a pore . Bhatt et al (1992) studied the important role of interface in controlling the effective thermal conductivity of composites. In particular, one can use the measurement of thermal conductivity as a nondestructive tool to determine the integrity of the fiber/matrix interface.…”

An eigenfunction expansion–variational method in prediction of the transverse thermal conductivity of fiber reinforced composites considering interfacial characteristics

“…A lot of investigations (for example by Hasselman and coworkers [1,2]) show that interfacial gaps exist, which are formed mainly because of the mismatch in thermal expansion coefficients of constituents during the cooling process of manufacture. When the gap thickness is small compared to the mean free path of the gas molecules in the gap, heat conduction is independent of gap thickness.…”

Scattering of thermal waves and non-steady effective thermal conductivity of composites with coated particles

“…Thus, the coating contributes to the character of the non-perfect interface. The dramatic effects of interfacial characteristics on the thermal conductivities and thermal diffusivities in particle [8] and fiber [9] reinforced composites have been experimentally demonstrated by Hasselman and his coworkers. Based on an equivalent inclusion concept, Hasselman and Johnson extended Maxwell's theory to the systems of spherical inclusions with contact resistance [10].…”
