    摘要： A simple manufacturing process for obtaining a carbon/carbon composite of superior performance is provided without using a carbon fiber fabric which is expensive and without going through the step of fixing fibers together using a binder.
    A precursor fiber for a carbon fiber which precursor fiber has been rendered infusible is subjected to uniaxial pressing at a temperature lower than the temperature adopted in the infusiblizing treatment, and then a carbonization treatment is performed.
    According to the present invention, a primary-pressed carbon material can be produced without using a binder, thus resulting in that not only the carbon material but also a carbon/carbon composite can be produced in a simple manner.
