Обоснование технологических режимов многократной пропитки-сушки и последующей автоклавной обработки для обеспечения требуемого состава материала
FIELD: chemistry. SUBSTANCE: invention relates to heat-resistant composite materials, which can be used in various industries, in particular in aircraft and space equipment, and to a method for preparing them. Described is a heat-resistant polymer composite material, containing siloxane rubber as a matrix and multi-wall carbon nanotubes (CNT) as filler in amount of 0.1–1.0 wt% per 100 g of pts.wt matrix, wherein material has heat resistance: weight change at 400 °C not more than 3.93 %, and physical-mechanical properties: modulus of elasticity in tension 0.93–3.63 MPa at relative elongation of 330–505 %. Also described is a method of producing polymer composite material. EFFECT: technical result is producing a novel polymer composite material with high heat resistance and improved mechanical properties based on siloxane rubber as a matrix and carbon nanotubes as filler. 6 cl, 9 dwg, 1 tbl, 8 ex
FIELD: chemistry. SUBSTANCE: multilayered coating contains three successive layers with an even thickness: a lower mirror metal radio-reflecting skin-layer of pure aluminium, an intermediate protective thermoregulatory dielectric layer of zirconium dioxide and an upper protective wear-resistant highly strong diamond-like carbon layer. EFFECT: provision of the operation in extreme conditions of open space due to the application of a thin substrate-envelope from a polymer composite material. 3 cl, 1 dwg
