FIELD: technological processes.
SUBSTANCE: invention relates to methods of producing porous materials, namely porous metal materials used in medicine for bone defect replacement in traumatology and orthopedics. Method involves preliminary formation of a metal mat from fibers with length of at least 100 mm and its further sintering. Before sintering metal mats are reinforced with straight or curved pieces of wire or meshes woven from it. Titanium or titanium nickelide is used as fiber and wire. Transverse size of the fibers of the metal mat is 20–60 mcm, and of the reinforcing wire is 0.1–1.2 mm. Porous-fibrous material is obtained by combining fibrous mats with different density of fibers. Layers of reinforcing wire and fibrous mats are alternated in accordance with required gradient of porous-fibrous material architecture.
EFFECT: invention enables to obtain a metal material with a gradient architecture, capable of plastic deformation.
