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
The pore structure of the pyrolysis residues of poiy-2.~dimethylphenyleneoxide (PPO) and oxidized PPO were studied by adsorption measurements. The Dubinin method with different gases as adsorbents was used for determination of the micropore volume. In all cases slit-shaped micropores were found, Pre
