Abstract
Specification of the carbon fibres (CF) model is proposed to the development of the Mileyko-Litvinov concept of the microcomposite structure of CF. A classical model defines the CF structure in the form of a fibrillar shell filled with microcomposite. Its matrix represents amorphous carbon of uncertain nature, and the filler - fibrils, with graphite crystallites as its main structural elements. The proposed model is different from the already known models due to accounting for the existence of pores – together with the two known phases of microcomposite – axially oriented fibrils and amorphous (matrix) carbon. It has been established that there are two fundamentally different types of pores: flat and spherical. The flat pores are limited by the surface areas of fibrils and matrix carbon, between which there is no adhesive interaction. The spherical pores are formed by the gaseous products of pyrolysis and carbonisation of CF during the molding stage of the filament. The following experimental data is referenced below in support of the complex four-phase microcomposite structure of the internal areas of the filament.
