TLDR
In this article, the authors used finite element analysis to estimate the transverse thermal conductivity of continuous fiber reinforced composites containing a random fiber distribution with imperfect interfaces, and compared with the classical solution of Hasselman and Johnson to determine limits of applicability.Abstract:
Estimation of the transverse thermal conductivity of continuous fiber reinforced composites containing a random fiber distribution with imperfect interfaces was performed using finite element analysis. FEA results were compared with the classical solution of Hasselman and Johnson to determine limits of applicability. The Hasselman and Johnson model predicts the effective thermal conductivity within 3 percent of the numerical estimates for interfacial conductance values of 1 × 10 -2 - 1 × 10 3 W/m 2 K, fiber-matrix conductivity ratios between 1 and 100, and fiber volume fractions up to 50 percent which are properties typical of ceramic compositesread more
