Abstract

The microstructure of a polymeric matrix in organoplasty on the basis of an aramide fabric and the multicomponent epoxy binding modified by polysulphone is investigated. It is established that phase heterogeneity is peculiar to a polymeric matrix: the one-phase microdisperse structure is characteristic for a microstructure of epoxy polymer in zones with dense packing of fibers (in a thread); the two-phase structure is characteristic for a microstructure of the epoxy polymer modified by polysulphone, in zones with less dense packing of fibers (between threads and fabric layers). With researches of a microstructure it is confirmed that when manufacturing the organoplasty on the basis of an aramide fabric and the meltable multicomponent epoxy binding happens redistribution of components of a reinforcing filler binding in interfiber space to a primary arrangement of polysulphone between threads and the fabric layers, bringing to formation of two-phase structure.
