Abstract
The invention relates to a guiding optical fiber. The guiding optical fiber comprises an optical fiber, a coating and a protective layer, wherein the coating is coated at the periphery of the optical fiber; the protective layer is extruded and molded at the periphery of the coating; and the protective layer is a carbon fiber reinforced polyvinyl fluoride protective layer. According to the invention, the carbon fiber reinforced polyvinyl fluoride is used as reinforced coating. Compared with the traditional guiding optical fiber, the guiding optical fiber provided by the invention has the advantages of excellent performance, simplicity for making, low cost and wide application range.
Description
?
Technical field
the present invention relates to field fiber, particularly a kind of guidance optical fiber.
?
Background technology
optical fiber technology is applied to intellectual weapon, and particularly the guidance of guided missile and ROV is just developed rapidly.Utilize Optical Fiber Transmission echo signal and strike order, make guided missile or torpedo accurately hit unfriendly target.1988, Germany and France manufactured experimently Polyphem's antitank missile, both can understand the image of target area through optical fiber in real time, can control missile-target impact by optical fiber again.Report is arranged recently, and U.S.Army Missile Command carries out poster presentation to the remote fiber seeker, and this guided missile can hit the outer moving target of 100km.The fibre tensile strength that the Polyphem uses is 40N; The flying speed of " Cyclops " anti-warship guided missle is more than 200 meter of a per second. it is the key technical problem in the optical-fibre guidance that optical fiber twines; Fibre optic guidance missile is wrapped on the special-purpose reel with optical cable usually; In the missile guidance process, can successfully discharge, to satisfy the missile flight rate request.Optical-fibre guidance has the major requirement of fibre-optic transmission system (FOTS): 1. winding construction is firm, and shared volume is little, and the added losses during fibre-optical bending are little, and 2. optical fiber can at a high speed smooth unwrapping wire, 3. loss minimum in the missile flight process.These targets to optical fiber in winding process and the moulding winding higher requirement has been proposed.Tensile strength: the tensile strength that fibre optic guidance missile (FOG-M) requires with optical cable depends on the missile operations distance like 10km, 15km, and the requirement of 20km and 30km～60km, thereby whole optical fiber is necessary for continuous length.Be to adapt to this special working method of wire-guided, one of gordian technique is to adopt a kind of working temperature extremely wide and do not influence the novel single-mode fiber that optical cable discharges; It two is on guided missile and launching guidance device, respectively to adorn a coiled optical fiber respectively to discharge, with avoid optical fiber draw tension and the load that alleviates guided missile.This scheme U.S. has obtained checking in the Naval Ocean System Center of Hawaiian Islands is tested as the fibre optic guidance missile of target drone with BGM-34; Simultaneously; In the Fibre Optic Missile Polyphem demonstration of moral, method joint research and development, for the benefit of optical cable discharges from the projectile tail reel, and guided missile adopts the rocket engine of side direction exhaust; Thereby avoided the air-flow damage optical cable of engine, guaranteed the normal operation of fibre optic guidance missile.
traditional guidance optical fiber is to adopt the wrapped or braiding outside tightly packaged fiber of organdy or aramid yarn, and reusable heat solidifies or the resin dipping of ultra-violet curing forms the anti-element of opening.This class formation complex process, outside dimension is not easy to do little, and practicality is relatively poor.
?
Summary of the invention
the object of the invention provides a kind of function admirable and makes simple guidance optical fiber.
in order to achieve the above object; The technical scheme that the present invention adopted is: a kind of guidance optical fiber; It comprises optical fiber, is coated on coating and the extrusion molding of the optical fiber periphery protective layer in the coating periphery, and described protective layer is that carbon fibre strengthens the PVF protective layer.
described optical fiber is G657 optical fiber, and its diameter is 0.124～0.126mm.
described coating is a polyimide coating, and its thickness is 0.014～0.016mm.
described carbon fibre strengthens PVF and comprises PVF, carbon fibre, thermal stabilizer, light stabilizer, nanoclay, and wherein the content of carbon fibre is 40%.
The external diameter of
described protective layer is not more than 1mm.
Owing to adopt technique scheme, the present invention has the following advantages
: the present invention serves as to strengthen to coat with the carbon fiber reinforced PVF.Compare with traditional guidance optical fiber, its function admirable is made simply, and cost is low, and is applied widely.
