Abstract

In this article the results of microstructural research of carbon fiber/epoxy composites produced by autoclave moulding and by vacuum infusion processing are represented. Research works are carried out by means of scanning electron microscopy in combination with the computer image analysis. The method of quantitative representation of results of microstructural research of fiber–matrix interface in carbon fiber reinforced polymers is suggested. The volume fraction of microdisperse phase in boundary layer is defined and it is shown that this parameter not linearly depends on distance from the surface of the fiber. The work is executed within implementation of the complex scientific directions 2.1. «Fundamental oriented research», 2.2. «Qualification and research of materials» («The strategic directions of development of materials and technologies of their processing for the period till 2030»)
