- Аннотация: In this paper, we propose a three-phase method for determining the effective properties of composite materials reinforced by whiskerized fibers. A modified composite consisting of two phases–a fiber and a whiskerized layer acting as a binder–is considered. For a modified composite loaded with longitu- dinal shear, calculations of the stress-strain state in each of the phases and calculations of effective properties are carried out. It is assumed that in the case of pure shear along the fiber, the strength of the composite is controlled by the binder; therefore, the deformed state in each of the phases of the modified composite is investigated and a comparative analysis with the deformed state in each of the phases of a similar classical composite is carried out. The calculated values of the effective longitudi- nal shear modulus and effective loss modulus are also subjected to comparative analysis. Two types of modified composites, whiskered by rigid carbon nanotubes (CNTs) and less rigid ZnO nanotubes, are investigated.
