Our aim here is to predict elongational flow‐induced enhancements in thermal or electrical conductivity of liquid crystal polymer (LCP) nano‐composites. To do so, we combine two classical mathematical asymptotic analyses: slender longwave hydro‐thermo‐dynamics for fibers and exact analysis of pure elongation of LCPs in solvents for bulk phases without boundary effects; and homogenization theory for effective properties of low volume‐fraction spheroidal inclusions. Two implications follow: elongational flow dominates fiber free surface and thermal effects on electrical and thermal conductivity enhancements; and, there appears to be no sacrifice in enhancements by producing much higher radius, bulk fibers.
