Analysis of elastomeric composites based on fiber-reinforced systems 2. Unidirectional composites

摘要

The elastic properties of unidirectionally reinforcedcomposite materials under large deformations were studied. Theapplied model for deformation on materials [1] was based onstructural macroscopic theory of stiff and soft composites [2],including micro- and macromechanical levels of analysis ofcomposite media. The properties of unidirectional elastomericcomposites were studied in tension and shear in the plane ofreinforcement. The microscopic fields in the structuralcomponents of composites having low-compressible andcompressible matrices were also analyzed. Changes in theparameters of macroscopical deformation of composites wereexamined as functions of the loading parameters and initialconditions of the structure. The evolution of structural changes indeformed composite materials is described.
