Abstract
The utility model discloses a non-metallic fiber reinforcement belt, which comprises a strip-shaped body, wherein the strip-shaped body has ductility and rigidity; the strip-shaped body comprises an adhesive firming body and a plurality of fibers; all fibers are arranged in the adhesive firming body; the extending direction of at least one fiber is identical to the extending direction of the strip-shaped body; and the cross section of the strip-shaped body is in the shape of a rectangle or an approximate rectangle. The non-metallic fiber reinforcement belt is packed outside an optical fiber, a beam tube or a cable core vertically during the optical cable manufacturing process, and then an outer sheath is squeezed. The non-metallic fiber reinforcement belt can avoid the problem that hydrogen evolution is caused due to iron oxidation; the low-temperature performance of an optical cable is excellent, and the low-temperature contraction of the beam tube cannot occur; and the thunderstruck possibility can be avoided when the non-metallic fiber reinforcement belt is used in thunderous areas. Meanwhile, the non-metallic fiber reinforcement belt has the advantages of small structural size and light weight. The appearance of the optical cable is more rounding.

Further, described complex root fiber evenly or periodically is distributed in the described adhesive solidification body.
Further, have at least the bearing of trend of a fiber identical with the bearing of trend of adhesive solidification body, remaining fiber becomes arbitrarily angled with the bearing of trend of adhesive solidification body.
Further, described remaining fiber interweaves or periodically interweaves.
Further, described tackifier is inorganic adhesive or organic adhesion agent, or natural adhesive or synthetic adhesive, or resin adhesive or rubber adhesive or compound tackifier, or thermoplastic adhesive or hot setting adhesive or hot melt adhesive.
Further, described tackifier is selected from any two kinds or the two or more combinations of inorganic adhesive, organic adhesion agent, natural adhesive, synthetic adhesive, resin adhesive, rubber adhesive, compound tackifier, thermoplastic adhesive, hot setting adhesive, heat sealing adhesive.
Further, described shoestring has cross direction tear strength.
Further, described complex root fiber is glass fibre or fragrant human relations or the low breaking elongation fiber of any one high elastic modulus, or the composite fibre of the arbitrary proportion of the low breaking elongation fiber of glass fibre, Fang Lun and high elastic modulus.
Further, two long in the xsect of described shoestring relative edges are approximate parallel, and two short relative edges are straight line or curve.
Further, the area sum of the xsect of described complex root fiber account for shoestring cross-sectional area 60%～97%.
Further, any surface finish of shoestring.
Further, coated is gone up at least one surface of shoestring one deck powder.
