Model for an explanation of embrittlement polymeric is offered composites, in which the filler modifies structure matrixes, thus the properties of a composite are defined (determined) by the charactristics of such matrix. Is shown, that the reason of embrittlement in reduction of a degree of the local order of a polymeric matrix and increase of the size of critical structural defect.
