FIELD: technological processes.
SUBSTANCE: highly-filled polymer compositions are used for manufacture of destructible mandrels used in winding of high-strength items from composite materials. Composition contains the following components, wt %: silica sand 100-1,000, polyvinyl alcohol 3-80, nanodispersed filler aerosil 4-6. Introduction of aerosil into composition in the form of nanodispersed filler makes it possible to increase coefficient of mandrel heat conductivity by change of density and more homogeneous structure of hardened polymer composition.
EFFECT: improvement of item performance properties.
