FIELD: medicine, pharmaceutics.SUBSTANCE: invention refers to medicine. A composite inner retainer comprises an inner retainer for fracture contraction. The above inner retainer comprises a number of layers, each of which contains a composition of thermoplastic material and a component of thermoplastic material. Each of the number of layers contains fibres forming a specified pattern of their angular orientation. The specified patterns of fibre angular orientation are symmetrical to the first to last layers. The symmetrical arrangements of the patterns of the fibre angular orientation comprises at least two layers, substantially with the opposite fibre angular orientation.EFFECT: invention makes it possible to specify the load-deflection curves in response to the effect of compression, deflecting and twisting forces.15 cl, 40 dwg, 1 tbl |
