High tensile strength, high Young's modulus carbon fiber, free from holes and voids having a statistical probability of holes detected by a standard plasma etching test of less than about 2%, a tensile strength of at least about 150 kg/mm2 and a Young's modulus of at least about 15 x 103kg/mm2. The carbon fiber has excellent homogeneity of internal structure and excellent reliability as a composite material. |
