Project summary

The project is aimed at the elaboration of new composite materials with improved physical-mechanical characteristics.

It can be achieved through the formation of a spatial pattern of chemical links as well as through the introduction of new promising fillers into a polytetrafluoroethylene matrix.

The merits of the materials in question are their high radiation resistance, depreciation resistance, lack of creep and cracks under load and an outstanding resistance to corrosive environment.

The project is characterized by the following traits:

- The elaboration of the technology is based on a new scientific trend of chemical modification of the isotrope-reinforced polytetrafluoroethylene.

- In order to reduce the amount of experiments and to optimize the structure of the composites mathematical modelling, specially elaborated algorithms and programs are used.

The materials in question are to be applied in mechanical engineering, instrument-making and nuclear industry robotics.

Preliminary investigations have shown that the method proposed ensures a 10-fold increase in radiation resistance and a 100-fold increase in depreciation resistance.
