Influence of the concentration and dispersity of the filler on the creep of polymer composite

Mechanics of Composite Materials Aims and scope

Conclusions

  1. 1.

    We discovered that the principles of concentration-time analogy and of analogy to the parameter f (specific surface of the particles of filler) can be applied to describe the diagrams of short-term creep and to predict long-term creep of polyester resins with different concentration and dispersity of the filler (cement). It was experimentally established that the greater the dispersity of the filler is, the larger is the function of concentration-time reduction.

  2. 2.

    Modeling and calculation of the strain properties of a composite according to the properties of the structural components showed that around the particles of filler there may exist an interfacial film whose rigidity is poorer than the rigidity of the matrix, and the thickness decreases with increasing phase boundary in the composite. In that case damage may cumulate under conditions of creep of the composite.
