We developed a model of a composite material on the base of which the effect of temperature on the strength of the linear-reinforced system of epoxy matrix - boron fibers is studied. The condition of aver- aging of microstresses on the microscopic volume is assumed to be valid (representative element). In the particular case under an appropriate choice of the microscopic volume, the conditions of continuity of displacements at the interfaces between them are fulfilled.
