Dispersed Reinforced Radiation-Resistant Composites

Prospects for nuclear branch of creation of the screens providing protection against radiation and possessing constructional properties are shown. Use as binding non-isocyanate polyurethane of the urethane synthesized as a result of nonconventional reaction between oligoether with trailer cyclocarbonate groups and diethylenetriamine is proved. It is established that the received binding possesses the large number of hydrogen communications providing effective absorption of gamma radiation and a neutron stream. Key shortcomings of polymeric binding – dependence of the physicist – mechanical characteristics from temperature and difficult predicted durability are revealed at a radiation warming up. Solutions of the specified problem by introduction of the reinforcing components – polyamide and glass fibers are shown. The rational maintenance of the filling group providing the necessary technological viscosity corresponding to a molding way of production of products is defined. Results of determination of concentration of the reinforcing fibers of various types in a radiation resistant composite are presented. Dependences of «tension deformation» for composite samples at compression and stretching in various temperature conditions are established. Improvement of heat physical characteristics of the reinforced compositions and increase of values of durability is proved. Technological conditions of receiving effective composites of various types reinforced by fibers are defined. For the studied compounding values of linear coefficients of easing scale of radiation are established.
