Analytical formulas are derived and an analysis of sensitivity of angle-ply composite structures to deviations of their elastic characteristics is performed. It is shown that the properties of the structures are determined mainly by their degree of anisotropy - the ratio of the longitudinal elastic modulus of a unidirectional material to its transverse one. For the basic classes of composites (high-, medium-, and low-modulus carbon-fiber, organo-, and glass-fiber plastics), recommendations for a rational choice of their structures to obtain experimental results allowing one to identify the elastic characteristics of unidirectional composites are formulated.
