英文摘要 | Thermal expansion of differently-textured pyrolytic carbon matrices (pyrocarbons) of carbon/carbon composites was studied with a high temperature X-ray diffraction at temperatures ranging from 25 degrees C to 1400 degrees C. The composites were synthesized by chemical vapor infiltration of a carbon fiber felt, using methane as a carbon source. From the linear dependence of the lattice displacement on temperature, coefficients of thermal expansion (CTE) of the pyrocarbons were calculated. One-dimensional thermal expansion along the (002)-direction (c-axis) of the pyrocarbons was found to be proportional to the composite synthesis temperature. A correlation between CTE and pyrocarbon texture was found: low-textured pyrocarbon with an extinction angle (Ae) of 10 degrees exhibits a smaller CTE of 2.02 x 10-5 K-1, whereas high-textured pyrocarbon with an Ae of 22 degrees exhibits a considerably higher CTE of 2.65 x 10-5 K-1. However, CTE of high-textured pyrocarbon is still smaller than that of graphite, which is 2.9 x10-5 K-1. |
