Abstract

A resin-impregnated, structural fiber rope includes a plurality of tows disposed in a bundle, each of the plurality of tows including a plurality of structural fibers, and uncured polymeric resin impregnated into the bundle. Each of the plurality of structural fibers defines an angle with respect to a central axis of the rope of no more than about 10 degrees.

Claims (14)

1. A resin-impregnated, structural fiber rope, comprising:

a plurality of tows disposed in a bundle, each of the plurality of tows including a plurality of structural fibers; and

uncured polymeric resin impregnated into the bundle;

wherein each of the plurality of structural fibers defines an angle with respect to a central axis of the rope of no more than about 10 degrees; and

wherein the plurality of tows are twisted about one another.

2. The resin-impregnated, structural fiber rope, according to claim 1 , wherein each of the plurality of structural fibers defines an angle with respect to a central axis of the rope of no more than about 5 degrees.

3. The resin-impregnated, structural fiber rope, according to claim 1 , wherein the fibers of each of the plurality of tows are twisted about one another.

4. The resin-impregnated, structural fiber rope, according to claim 3 , wherein the fibers of each of the plurality of tows are twisted about one another in a direction opposite to the twist direction of the rope.

5. The resin-impregnated, structural fiber rope, according to claim 1 , wherein the plurality of fibers comprises a material selected from the group consisting of a thermoplastic polymer, a thermosetting polymer, and a liquid crystal polymer.

6. The resin-impregnated, structural fiber rope, according to claim 1 , wherein the plurality of fibers comprises a material selected from the group consisting of an epoxy polymer, a polyamide-imide polymer, a polyaryletherketone polymer, a polyetheretherketone polymer, a polyimide polymer, a polyphenylene sulfide polymer, a polyester polymer, and a vinyl ester polymer.

7. The resin-impregnated, structural fiber rope, according to claim 1 , wherein the rope exhibits a generally round shape in cross-section.

8. The resin-impregnated, structural fiber rope, according to claim 1 , wherein the rope exhibits a diameter of less than about 2 millimeters.

9. The resin-impregnated, structural fiber rope, according to claim 1 , wherein the rope exhibits a diameter within a range of about 0.7 millimeters to about 1.6 millimeters.

10. The resin-impregnated, structural fiber rope, according to claim 1 , wherein the plurality of structural fiber comprises a material selected from the group consisting of carbon fibers, graphite fibers, glass fibers, and aramid fibers.
