The numerical prediction of effective thermoviscoelastic properties of unidirectional fiber composite with the viscoelastic components

The problems of numerical identification of effective thermoviscoelastic properties of the unidirectional reinforced polymeric composite on the base of components properties are considered. General statement of a boundary value problem of thermoviscoelasticity for a cell of periodicity is yielded; special computing experiments for searching effective properties of a composite are featured. The effect of a volumetric relaxation of the binder on the properties of the unidirectional composite is considered. Effective generalized functions of a relaxation of unidirectional organoplasty and effective functions of temperature-time shift are gained. It is confirmed that organoplasty shows simple thermorheological behaviour at presence of simple thermorheological behaviour of fibers and the binder. Simple thermorheological behaviour of organoplasty at presence of simple thermorheological behaviour of fibers and the binder is confirmed.
