Effect of Heat-treatment Temperature on Mechanical Properties of Pyrocarbon and Carbon/Carbon Composites

Carbon/carbon composites were infiltrated by isobaric, isothermal chemical vapor infiltration using propane as the carbon source. Effects of heat-treatment temperature up to 2500 degrees C on the microstructure and the mechanical properties of pyrocarbon and carbon/carbon composites were investigated by X-ray diffractometry, polarized light microscope, scanning electron microscope, nanoindentation, and three points bending tests. The...
