Abstract

The scanning electron microscopy method (SEM) by special technique of high reso-lution has investigates deformation of microphase structure of surface fracture of poly-meric matrix in epoxy carbon-, glass- and organoplastics at mechanical loading. It is shown that under the influence of mechanical loading of composite there is reorganiza-tion of structure of matrix. It is revealed that thermosetting polymeric matrix in the course of mechanical loading are capable (is plastically irreversible) to be deformed up to partial or complete disintegration assotsiats particles of disperse phase with formation of structures of linear type. It is shown that of surface fracture epoxy carbon-, glass- and organoplastics at mechanical loading is defined by the deformation processes of «torsionny» (rotational) type connected with mutual turn of local volumes of matrix (torsions).
