BEARING TUBE MADE FROM COMPOSITE FIBROUS MATERIAL FOR MANUFACTURING LOW EXTREMITY PROSTHESIS Russian patent published in 1995 - IPC

FIELD: medical engineering. SUBSTANCE: bearing tube 1 has hollow cylindric casing manufactured from layers 2 of carbon fiber reinforced plastic. New is that carbon fiber reinforced layers 2 are placed between at least one external fiber glass reinforced layer 3 and one internal fiber glass reinforced layer 4. Fiber carbon reinforced laminate layers 2 and fiber glass reinforced laminate layers 3 and 4 are arranged in the form of a coaxial structure. Layers 2-4 are also composable of spiral coils of fiber glass and carbon reinforced laminates. Filaments in layers 2 of fiber carbon reinforced laminate are to be directed along the tube generatrix and in layers 3 and 4 made of fiber glass reinforced laminates are to be directed circumferentially. EFFECT: lower cost and improved mechanical properties of tubes to be used for medical purposes. 4 cl, 5 dwg
