Thermophysical Properties of Radiation-Protective Composite Materials

[摘要] The paper discusses the development of compositions and studies of the properties of heavy composite materials with atypically high heat insulating performance. When choosing the suitable matrix material, epoxy resin, sodium liquid glass and Portland cement were tested. Filler in all compositions was a lot of tonnage waste of the glass industry - heavy flint. The degree of filling of the matrix material in the preparation of press composites reached 95...97% (by volume). This allowed to increase the average density of the material to 3800 ... 3850 kg/m3 and provided the required level of protection against penetrating radiation.
