Graphitization of carbon fibre/ glassy carbon composites
TL;DR: The graphitization of carbon fiber/glassy carbon composites was found to start at the boundary between the fibres and glassy carbon matrix, and to proceed into the matrix as discussed by the authors.
Journal ArticleDOI
Electronic properties and band model of carbons
TL;DR: In this article, the early electronic energy band model of carbon and its later modifications such as faster collapse of energy gap and the presence of band overlap in graphites are recalled to introduce the main topic of the paper.

Structures and physical properties of carbon fibers from coal tar mesophase pitch
TL;DR: In this article, two kinds of spinning, spinning with stirring the pitch above a capillary and without stirring, have been tried to form pitch fibers from coal tar mesophase pitch.

Graphitizability of carbonaceous materials as studied by TEM and X-ray diffraction
A. Oberlin,M. Oberlin +1 more
TL;DR: In this paper, the authors measured the probability of finding a carbon layer pair reaching the graphite order in the solid by using X-ray patterns and found that the maximum possible value of P depends only on the size of the oriented areas, which itself depends on the elemental composition at the very moment of its production.
