Irradiation behavior of carbon-based composite materials

Consideration is given to the data on radiation changes of sizes and some properties of different carbon-based composite materials (carbon-graphite and graphite-graphite compositions; carbon-carbon composite materials with carbon reinforcing fibers; carbon-silicon compositions), irradiated by neutrons at 320-1700 k. It is shown that change of sizes is dictated by the type and the ratio of components, forming (or not forming) the reinforcing uniform frame. 22 refs.; 10 figs
