Study of the physical and mechanical characteristics of modified epoxy matrices and reinforced plastics using modern computer systems for calculations

Abstract

For the first time, calculations of a reinforced polymer composite material (ArPCM) based on T-25 fabric (VMP) and developed modified epoxy matrices with an active diluents (AR) of different nature, structure and characteristics (laproxides and laprolate), a complex of physical and mechanical characteristics were performed using a generalized 3D models of the elementary structural cell of the anisotropic material ArPKM and computational engineering systems (CAE). Calculations and experiments have shown that all the studied modified epoxy matrices can be used in the design of products from ArPKM, however, preference should be given to matrices with E-181 and DEG-1 grade Laproxides, which fully meet the strength requirements for designing products subjected to forces during operation.
