Tensile creep-rate of pyrolytic carbon
Stress-change technique, combined with a graphical-interpolation analysis, yields data on the stress and temperature dependence of the creep rate over broad strain and stress or temperature ranges on as-deposited, substrate-nucleated, pyrolytic carbon
Magnetic susceptibility of glassy carbon
Magnetic susceptibility of glassy carbon at room temperature with respect to magnetic field strength, heat treatment temperature, and high temperature tensile deformatio
Tensile creep-rate studies on pyrolytic carbon
Tensile creep behavior of substrate-nucleated pyrolytic carbon at high temperature
Structure dependence of the diamagnetism of graphitizing carbons
Structure dependence of diamagnetism in pyrolytic carbon
Basal-plane metallography of deformed pyrolytic carbon
Cleavage technique is recommended over the normal polishing technique in preparing pyrolytic carbon for metallographic examination of basal-plane surfaces. After careful removal of torn basal-plane fragments and other cleavage debris with cellulose tape, the true structure is clearly revealed
Tensile and structural properties of glassy carbon
High temperature tensile strength of glassy carbons in helium atmosphere - mechanical propertie
Structural studies on carbon materials for advanced space technology. Part 1: Structure and oxidation behavior of some carbon/carbon composite materials
The microstructure and some microstructural effects of oxidation have been investigated for laminar carbon fiber cloth/cloth binder matrix composite materials. It was found that cloth wave is important in determining the macrostructure of the composites X-ray diffraction analysis showed that the composites were more graphitic than the constituent fiber phases, indicating a graphitic binder matrix phase. Various tests which were conducted to investigate specific properties of the material are described. It was learned that under the moderate temperature and oxidant flow conditions studied, C-700, 730 materials exhibit superior oxidation resistance primarily because of the inhibiting influence of the graphitized binder matrix
