Abstract : The thermophysical property study of a phenolic-carbon (fiber) material, designated as Narmco 4028, was performed under Master Agreement Contract NAS 1-5448, Task Order 3. Both the nondegraded (virgin) and thermally degraded (charred) forms were evaluated over temperature ranges of -200 deg F (144 deg K) to 750 deg F (673 deg K) for the virgin material and 1000 deg F (811 deg K) to 5000 deg F (3033 deg K) for the charred material. The thermally degraded material was prepared in an induction plasma torch with a heat flux density of 170 Btu/sq ft/ sec (193 x 10(exp 4) watts/sq meters). Some chars for the thermal conductivity evaluations were made in a high temperature furnace.
