COMPOSITE MATERIAL FOR REPLACEMENT OF BONE TISSUE Russian patent published in 2014 - IPC A61L27/08 A61F2/28 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, in particular to the field of composite materials for manufacturing endoprostheses. A composite material for replacement of bone tissue contains a porous matrix from crystalline carbon fibres with an inter-plane distance 3.58…3.62 angstrom with a content of fibres 20…80 of its total volume and a filling material, which contains crystalline carbon with an inter-plane distance 3.42…3.44 angstrom. In creation of the composite material for bone tissue replacement with an elasticity modulus, corresponding to the human bone tissue, the filling material contains obtained by Bakelite carbonisation amorphous carbon in the form of coke in an amount of 10…20% and obtained by methane decomposition crystalline carbon in an amount of 70-50% respectively of the total volume of the matrix pores.

EFFECT: composite material has the elasticity modulus, corresponding to the elasticity modulus of the human bone tissue.
