DOWNLOAD EBOOK →Advanced thermal protection materials envisioned for use on future hypersonic vehicles will likely be subjected to temperatures in excess of 1811 K (2800 F) and, therefore, will require the rapid conduction of heat away from the stagnation regions of wing leading edges, the nose cap area, and from engine inlet and exhaust areas. Carbon-carbon composite materials are candidates for use in advanced thermal protection systems. For design purposes, high temperature thermophysical property data are required, but a search of the literature found little thermal conductivity data for carbon-carbon materials above 1255 K (1800 F). Because a need was recognized for in-plane and through-the-thickness thermal conductivity data for carbon-carbon composite materials over a wide temperature range, Langley Research Center (LaRC) embarked on an effort to compile a consistent set of thermal conductivity values from room temperature to 1922 K (3000 F) for carbon-carbon composite materials on hand at LaRC for which the precursor materials and thermal processing history were known. This report documents the thermal conductivity data generated for these materials. In-plane thermal conductivity values range from 10 to 233 W/m-K, whereas through-the-thickness values range from 2 to 21 W/m-K.

DOWNLOAD EBOOK →The objective of this project was to develop a low-cost, high thermal conductivity carbon/carbon composite with a mesophase pitch-based matrix. A low cost, continuous powder coating process was developed which allows the production of a flexible pre-impregnated pitch-based powder. This process was used to produce towpreg from AR mesophase pitch powder and three different carbon fibers: T300 PAN-based fiber, P55 pitch-based fiber, and an experimental high thermal conductivity pitch-based fiber. The thermal conductivities parallel to the fibers of the graphitized T300/AR-120 and P55/AR-120 composites was 80.5 and 135.5 W/m-K, respectively. The ribbon fiber enforced composites exhibited thermal conductivities parallel to the fiber and transverse to the fiber of 145 and 213.5 W/m-K, respectively. This indicates fiber shape can affect matrix properties. A finite element model was developed to predict the thermal conductivity of carbon/carbon composites, both parallel and transverse to the fiber direction, composed of isotropic and anisotropic materials. The model was able to accurately predict the average thermal conductivity of the composites made in this study. p2.
