HYBRID COMPOSITE CABLE

摘要

The essence of invention expresses the structure of hybrid composite cable (1), which consists from the high strength composite material load-bearing core component, carbon fiber reinforced plastic for example, and external steel component. One variant of the suggested hybrid composite cable with the variable by the length cross-sectional areas is shown in Fig.1., where 1-1, 2-2, 3-3 and 4-4 cross-sections, which are differed by the area of steel component cross-section; (2) - leveling layer of the glue, which join together all the elements of the cable by it edges; (6), (7) - high strength composite material load-bearing layers of core components, carbon fiber reinforced plastic, for example; (3), (4), (5), (8), (9), (10) - layers of steel strands; (11) - additional fasteners, which provide invariability of cross-sectional shape by the cable's length; (12) - weldings which provide joint work of steel strands. The suggested hybrid composite cable can be used in structures, where load-bearing elements are straight, as the anchors of several structures, for example, concaved down as in saddle-shaped cable roofs and cable bridges, or concaved up as stressing structural elements. The task of suggested hybrid composite cable is taking up of the loads, acting in the cases, when high strength composite material loose it load-bearing capacity and steel strands are able to take up the forces, which just sufficiently decreased due to the yielding deformation of steel strands and corresponding elongation of the cable.
