Vapor Infiltration

Carbon/Carbon composites were fabricated by microwave pyrolysis chemical vapor infiltration. The carbon fiber felts (the bulk density ~0.2 g/cm3) were infiltrated from methane at temperature of 1075°C, 1100°C, 1125°C and 1150°C, methane partial pressure ranging from 5KPa to 15KPa, and gas residence times of 0.05s ,0.1s, 0.15s and 0.2s. The effect of residence time, deposition temperature and partial pressure of source gas on the textures was studied by polarized-light microscopy. The results show that the anisotropy of texture is better when the parameter is higher; and rough layer texture can be fabricated easily by microwave pyrolysis chemical vapor infiltration.
