摘要：

ATTEMPTS to derive a structural model for high-strength carbon fibres have led to studies of the development of microporosity during heat treatment. X-ray scattering and helium density measurements1 showed that carbonized rayon fibres have a fibrillar structure, with chains of graphite crystallites arranged parallel to the fibre axis and giving rise to needle-shaped micropores between the fibrils. The average diameter of the pores perpendicular to the fibre axis seems to vary from 6 to 20 for heat treatments in the range 900°-2,900°C. © 1969 Nature Publishing Group.
