Technical Field

The utility model relates to the technical field of ropes, in particular to a brittle fiber rope.

Background

At present, the reason why brittle fibers are difficult to manufacture into ropes with good flexibility and high tensile strength is that brittle fibers such as basalt fibers, glass fibers, carbon fibers, boron fibers, aluminum oxide fibers and the like have high tensile strength, but have the defects of small deformation and elongation, larger decrease of fiber strength along with fiber length, poor flexibility and the like.

Therefore, after the brittle fiber is woven into the rope, the stress of the brittle fiber rope is reduced greatly due to the bending of the fiber material, and the high-strength adhesive tightly bonds the straight fiber filaments together, but the bonded fiber rope still has stress concentration after being stressed due to the high strength of the adhesive, has poor flexibility and is easy to break.

Example 1

This embodiment provides a brittle fiber rope, as shown in fig. 1, comprising: a brittle fiber aggregate 3 and a protective sleeve 4 woven on the outer surface of the brittle fiber aggregate 3; the brittle fiber total bundle 3 is formed by arranging a plurality of brittle fiber straight filaments 1 in a straight line, a protective sleeve 4 is formed on the outer surface of the brittle fiber total bundle 3 in a braiding mode, and the brittle fiber total bundle 3 and the protective sleeve 4 are bonded through silica gel infiltration.

The brittle fiber total bundle 3 is formed by circularly arranging brittle fiber straight filaments 1; the protective sleeve 4 is woven by sleeve fibers and is used for bearing pressure and resisting abrasion to protect the brittle fiber straight filaments 1 inside; the structure is suitable for being manufactured into a brittle fiber rope with the outer diameter of 1-60mm, and meanwhile, the brittle fiber rope can be used for occasions with long-term tensile force such as high-voltage wire cores or bridge guys.

As shown in fig. 2, to further protect the protective sleeve 4, the outer surface of the protective sleeve 4 is encapsulated to form a rubber sleeve 5, and the rubber sleeve 5 is made of silica gel, polyethylene, polyvinyl chloride, rubber or polyurethane.

The setting of gum cover 5 has increased the compression area and the bending radius of brittle fiber rope, has reduced the maximum stress of brittle fiber straight filament 1 in the brittle fiber rope, has consequently strengthened the compressive resistance, the wear resistance of brittle fiber rope. The structure is suitable for being manufactured into a brittle fiber rope with the outer diameter of 2-80mm, and the brittle fiber rope can be used for occasions with long-term tensile force such as high-voltage wire cores or bridge guys.

As shown in fig. 3, the brittle fiber aggregate bundle 3 comprises a plurality of brittle fiber bundles 2, wherein the brittle fiber bundles 2 are composed of a plurality of brittle fiber straight filaments 1;

specifically, a plurality of bundles of brittle fiber straight yarns 1 are bonded by silica gel or epoxy resin to manufacture small-diameter brittle fiber bundles 2, and then the small-diameter brittle fiber bundles 2 are woven into a large-diameter brittle fiber total bundle 3; and then the outer surface of the brittle fiber aggregate 3 is woven into a protective sleeve 4 by sleeve fibers, and the outer surface of the protective sleeve 4 is further protected by a rubber sleeve 5.

The structure is mainly arranged in that after the small-diameter brittle fiber bundles 2 are woven into the large-diameter brittle fiber total bundles 3, each small-diameter brittle fiber bundle 2 is repeatedly bent and forwards in the longitudinal direction of the brittle fiber rope and is interwoven with each other, and when the brittle fiber rope is bent, the actual length of the internal brittle fiber bundles 2 is larger than the length of the brittle fiber rope, so that the brittle fiber rope is easier to bend and twist; when the brittle fiber ropes are subjected to tensile force, the forces among the brittle fiber bundles 2 are continuously transmitted, so that the balanced stress is more easily achieved, the damage of the individual brittle fiber bundles 2 can not cause larger influence on the whole bearing capacity of the brittle fiber ropes, meanwhile, the whole flexibility of the brittle fiber ropes is greatly improved, and the application range of the brittle fiber ropes is enlarged. Is most suitable for manufacturing brittle fiber ropes with the outer diameter of 11-200 mm.
