FIELD: rocket and space technology.
SUBSTANCE: invention is related to materials with a low temperature coefficient of linear expansion. A wood-polymer composite including carbon-containing fibres for which activated wood pulp is used, additionally contains polymethyl methacrylate, acetone, dibutyl phthalate in the following ratio of components, parts by weight: activated wood pulp 50-75, polymethyl methacrylate 10-15, acetone 5-10 , dibutyl phthalate 5-10.
EFFECT: density and coefficient of thermal linear expansion of the wood-polymer composite decreases.
