✦ Synopsis

The flash method is extended to measure directly the thermal diffusivity of graphite/carbon fiber in unidirectionally fiber-reinforced composites and also in fiber bundles. The thermal diffusivity was measured using both composities and fiber bundles for Morganite II and Thornal 50 S graphite fiber and for composite samples containing PX 505 carbon fiber. In addition, the thermal diffusivity of Morganite II and Thornel 50 S graphite fiber was calculated from the effective thermal conductivity of composite samples measured by an absolute method. The thermal diffusivity of MOD-3 fiber-reinforced graphite was measured and the results were used to compute the thermal conductivity in the three orthogonal directions. 7.5-8.04' 6.6-7.4 Continuous To+* Yarn 2 ply** Yarn 2 ply' Meter-long To@* Proprietary** Q=W** Round** Crenulated** 10.000+ Graphite Graphite carbon ( 85%) + Electrical Resistivlty 1400 y ohm om~ 6.06 ohm cm+ * From reference (111. ** From reference (121. + Ron, Air Force Material8 LabOratoI'y. f From reference (131.
