Carbon fiber production using high pressure treatment of a precursor material
Patent
·
OSTI ID:5616187
A process for producing a carbon fiber includes the steps of heat treating a selected precursor material under high pressure, thereafter solvent extracting the treated precursor material to obtain mesophase pitch, spinning the mesophase pitch into at least one pitch fiber, thermosetting the pitch fiber, and carbonizing the pitch fiber to obtain the carbon fiber.
