FIELD: medicine.
SUBSTANCE: invention relates to medicine, orthopedics. Pelvis joint arthroplasty cup is made of a composite material. Material comprises a porous matrix of crystalline carbon fibers with an interlayer distance of 3.58…3.62 of angstrom, with a total amount of fiber of 20…80 %. Filler material consists of crystalline carbon with an interlayer distance of 3.42…3.44 of angstroms in an amount of 50…70 % and amorphous carbon in the form of coke in an amount of 10…20 % of the total pore volume of the matrix. Carbon nanotubes are embedded in amorphous carbon in an amount of 0.05…1.0 % of the amorphous carbon mass.
EFFECT: invention provides endoprosthesis strength increased to values equal to or higher than the maximum strength of human bone tissue.
