This disclosure generally pertains to a method for manufacturing a distributed optical fiber scrim comprising a functional optical fiber, the functional optical fiber scrim thus manufactured, and composites in which an optical fiber scrim is incorporated. The present disclosure describes a variety of textile scrims, particularly adhesively bonded nonwoven scrim materials, each comprising at least one optical fiber with a continuous path across at least the length or width of the fabric. Such optical fiber scrims may be useful as sensor components (for example, as a detector of breakage, strain, pressure, or torque), as illumination components (for example, in a variety of light-providing applications), or as data-distribution components, either alone or in combination with other materials, such as fabrics, films, foams, and the like.

We claim: 1. An optical circuit and sensor system comprising: an optical fiber scrim comprising at least one warp yarn set having at least two warp yarns and at least one crossing yarn that crosses said warp yarn set in a sinuous path across the warp yarn set, wherein at least one of said crossing yarns is an optical fiber, and wherein said optical fiber has a change in light transmission characteristics when exposed to one or more sources selected from the group consisting of mechanical agents, chemical agents, moisture, temperature, pH changes, biological sources, neutrons, and ionizing radiation; a light source and coupling connected to a first end of the optical fiber in the optical fiber scrim such that the light from the light source is directed through the coupling into the first end of the optical fiber; and, a detector connected to a second end of the optical fiber, the second end of the optical fiber being the end of the fiber opposite to the first end of the fiber, wherein the detector measures the light emitted from the optical fiber. 2. The optical circuit and sensor system of claim 1, wherein said optical fiber scrim has a construction selected from the group consisting of an adhesively bonded laid scrim, a thermally bonded laid scrim, a woven scrim, a weft-inserted warp knit scrim, a multi-axial knit scrim, a stitch-bonded scrim, and a cross-plied scrim. 3. The optical circuit and sensor system of claim 1, wherein said warp yarn set has yarns that are present in an amount of between about 1 yarn per every 60 inches and about 25 yarns per inch. 4. The optical circuit and sensor system of claim 1, wherein said warp yarn set has yarns that are present in an amount of between about 1 yarn per 30 inches and about 12 yarns per inch. 5. The optical circuit and sensor system of claim 1, wherein said optical fiber has a core made of a material selected from the group consisting of glass and polymers. 6. The optical circuit and sensor system of claim 1, wherein the optical fiber is of a type selected from the group consisting of single mode fibers, multi-mode fibers, light pipes, photosensitive fibers, polarization-maintaining fibers, multiple step-indexed fibers, graded index fibers, reduced cladding fibers, high index fibers, wave-guiding films, and photonic lattice fibers. 7. The optical circuit and sensor system of claim 1, wherein said optical fiber is a single-mode fiber. 8. The optical circuit and sensor system of claim 1, wherein the optical fiber comprises a compressible sheath. 9. The optical circuit and sensor system of claim 1, wherein more than one optical fiber crosses said warp yarn set. 10. The optical circuit and sensor system of claim 1, wherein said optical fiber scrim comprises a plurality of said crossing yarns, said crossing yarns being selected from the group consisting of polyesters, polyamides, polyolefins, ceramics, fiberglass, aramids, cotton, wool, metal, carbon, and combinations thereof. 11. The optical circuit and sensor system of claim 1, wherein said warp yarn set comprises yarns selected from the group consisting of polyesters, polyamides, polyolefins, ceramics, fiberglass, aramids, cotton, wool, metal, carbon, optical fibers, and combinations thereof. 12. The optical circuit and sensor system of claim 11, wherein said warp yarn set further comprises at least one optical fiber. 13. The optical circuit and sensor system of claim 1, wherein the optical fiber has a square pattern construction. 14. The optical circuit and sensor system of claim 1, wherein said optical fiber scrim has a tri-axial pattern construction. 15. The optical circuit and sensor system of claim 14, wherein said tri-axial optical fiber scrim has a construction in which said crossing yarns are present in an amount of between about one of said crossing yarns per six inches and about four of said crossing yarns per inch in an upward diagonal direction and a downward diagonal direction. 16. The optical circuit and sensor system of claim 1, wherein the optical fiber scrim is an adhesively bonded scrim. 17. The optical circuit and sensor system of claim 16, wherein said optical fiber scrim is attached to a flexible carrier sheet, said carrier sheet being selected from the group consisting of films, foils, nonwoven fabrics, woven fabrics, and knit fabrics. 18. The optical circuit and sensor system of claim 1, wherein said optical fiber scrim comprises at least 2 different types of optical fibers.
