This paper investigates the thermal contact conductance across carbon fiber/epoxy resin composites under vacuum conditions at discrete contact pressures. Samples with unidirectional, continuous fibers oriented at 0 and 90 degrees to the contact interface are analyzed in 0/0 and 90/90 test configurations. Experimental results are compared with analytical data obtained using theory developed for homogeneous, isotropic, metallic contacts. As with earlier experiments in air, variations in the experimental data show the importance of material anisotropy and heterogeneity in governing thermal contact conductance between composites. While metallic theory can incorporate the anisotropic influence of fiber orientation, it fails to account for the distinct contributions of both fiber and matrix to the composite contact problem. 21 refs.
