Carbon fiber production using high pressure treatment of a precursor material |
摘要 |
A process for producing a carbon fiber includes the steps of heating a selected precursor material under high pressure, thereafter heating the precursor material under atmospheric pressure with sparging to form a 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.
