Based on the relations of the algebra of resolvent operators, the Volterra correspondence principle and the Rabotnov non-linear relation, a model allowing for the description of strain anisotropy of unidirectional composites under time-varying loading was developed. Using the experimental data of unidirectional CFRP specimens subjected to compressive loading at various angles to the direction of reinforcement and various strain rates as an example, the correctness of the proposed approach was shown. By applying the fundamental relations of the hereditary mechanics and the anisotropic elasticity theory, a series of interrelated material functions of the material was obtained and the mechanical behavior under various loading conditions was described.
