FIELD: composite materials.
SUBSTANCE: invention relates to composite materials with a ceramic matrix (CMC) for use in the aerospace industry and relates to a hybrid multilayer composite material with a ceramic matrix. Composite material comprises first facing sheet, second facing sheet and core arranged between first facing sheet and second facing sheet bonded thereto by binder. Each of the first facing sheet and the second facing sheet contains threads in the ceramic matrix. Composite material CMC is configured to receive temperature gradient, wherein first facing sheet is exposed to medium with higher temperature than second facing sheet. First facing sheet and second facing sheet have at least closely selected coefficients of thermal expansion, and first facing sheet has higher compression strength than second facing sheet.
EFFECT: invention provides creation of stronger structures of multilayer structures of CMC, having increased elasticity under conditions of temperature gradient.
