Abstract
The utility model relates to a carbon fiber reinforcement plate containing sensing fiber. The carbon fiber reinforcement plate comprises a carbon fiber plate body and at least one optical fiber sensor, wherein the optical fiber sensor is arranged inside or outside the carbon fiber body. Through additionally arranging the optical fiber sensor on the carbon fiber reinforcement plate, real-time and continuous distribution type measurement of internal temperature, stress and strain of the carbon fiber reinforcement plate is achieved; the sensing range is wide; and one optical fiber not only can be used for sensing, but also can be used for communication. As a built-in optical fiber sensor is formed in one time, the time and labor are saved; and a built-out optical fiber sensor can be mounted according to actual use without effect on the production of original carbon fiber.
Description
Technical field
the utility model relates to a kind of carbon fiber stiffener containing sensor fibre.
Background technology
carbon fiber reinforcement reinforcement sheet material, its moulding process is after the impregnated carbon fiber resin, in mould, to solidify and continuous pultrusion.Adopt high-quality carbon fiber raw material and good basic resin, carbon fiber board has the superperformances such as hot strength is high, corrosion resistance, shock resistance, impact resistance.The carbon fiber board of making can be given full play to intensity and the modulus of elasticity of carbon fiber, and in the resin solidification stage that can exempt carbon fiber one-way fabric when construction, the intensity utilization ratio is high, easy construction.Therefore, carbon fiber board is widely used in: concrete beam bending resistance, Shear Strengthening, concrete floor, bridge plate reinforcement and strengthening, concrete, brick masonry wall, the reinforcement of scissors wall, the post such as bridge pier, stake reinforcement and strengthening, the reinforcement and strengthenings such as chimney, tunnel, pond, concrete pipe.But the stress and strain of carbon fiber board inside is more difficult mensuration after moulding, the real time measure is more difficult.
Summary of the invention
the purpose of this utility model is to provide a kind of carbon fiber stiffener containing sensor fibre.
for achieving the above object, the technical solution adopted in the utility model is:
a kind of carbon fiber stiffener containing sensor fibre, it comprises carbon fiber board body, at least one Fibre Optical Sensor, described Fibre Optical Sensor is arranged on described carbon fiber board body interior or outside.
preferably, described Fibre Optical Sensor is arranged on described carbon fiber board body interior.
further preferably, described Fibre Optical Sensor penetrates and passes from the other end from an end of described carbon fiber board body.
further preferably, described Fibre Optical Sensor penetrates and is positioned at described carbon fiber board body interior from an end of described carbon fiber board body.
preferably, described Fibre Optical Sensor is arranged on the outside of described carbon fiber board body.
preferably, described Fibre Optical Sensor sticks on the external surface of described carbon fiber board body.
preferably, described Fibre Optical Sensor adopts the BOTDR system.
preferably, described Fibre Optical Sensor adopts the BOTDA system.
as follows for BOTDR system, BOTDA system introduction:
bOTDR system, BOTDA system are utilized the Brillouin scattering principle, and the BOTDR system, from an end input pumping pulse, detects centre wavelength and the power of inverse signal at same end, easy to use, but the spontaneous brillouin scattering signal is very faint, detection difficult; The tunable laser of BOTDA system in the optical fiber two ends injected sensor fibre by a pulsed light (pump light) and a continuous light (detection light) respectively, utilizes the stimulated Brillouin scattering effect, and scattered light intensity is stronger.
because technique scheme is used, the utility model compared with prior art has following advantages:
the utility model is by the carbon fiber stiffener, increasing Fibre Optical Sensor, and to realize real-time, the measurement of continuous distributed formula to carbon fiber stiffener internal temperature, stress and strain, sensing scope is long, and same optical fiber both can be used for sensing, also can be used for communication.The once production moulding of built-in fiber sensor, time saving and energy saving; The external optical fiber sensor can use be installed according to reality, on the production of original carbon fiber without impact.
