Abstract
The invention provides a kind of interim bridging materials, its preparation method is, first be put in mould shaping for the carbon fiber knit of 38-42 weight part, be poured in mould together with the nano-scale carbon filamentary material of the weight part of flexible epoxy vinyl ester resin 40-45 interpolation 10-15 weight part after the solidifying agent mixing of 5 weight parts is uniformly mixed; Adopt notch cuttype heating mode, be warmed to 90 degree of plus-pressures 65 kilograms to stop 8 minutes, uniform compaction, promote temperature again to 120 degree of stops 10 minutes, continue to be warmed to 160 degree stop 30 minutes after, have a power failure after being cooled to room temperature and take out in a mold, repair through roasting, polishing the sheet material that interim bridge formation is made on surface.Adopt carbon-fibre composite, intensity is high, quality is light, has both again the soft workability of textile fibres, is easy to compound, anisotropy, and design freedom is large, can carry out the design of kinds of schemes, with satisfied different goods to the requirement of its performance.
Description
Technical field
The present invention relates to novel material research and development field, particularly relate to a kind of interim bridging materials.
Background technology
Army is because of march, needs of building the road, and need the passage on temporary erection river course and the bridge of boats through river course, pass through for soldier and combatant facilities, this wartime, the interim bridge of boats must set up when needed within the extremely of short duration time.This pontoon bridge must possess that density is little, quality is light; High-modulus, high rigidity; High strength, Qiang Erjian; The features such as easy carrying, installation, dismounting.But traditional interim pontoon bridge is generally adopt wooden and irony equipment two kinds, and wooden bridge quality is light but intensity is little, firm not, and volume is relatively large, irony bridge quality is too large, and it is very inconvenient that carrying is got up, at substantial manpower and materials.
Summary of the invention
The object of the invention is to provide a kind of interim bridging materials, make it have that quality is light, intensity is high, the feature of easy carrying.
For solving the problem, the invention provides a kind of interim bridging materials, its preparation method is, first be put in mould shaping for the carbon fiber knit of 38-42 weight part, be poured in mould together with the nano-scale carbon filamentary material of the weight part of flexible epoxy vinyl ester resin 40-45 interpolation 10-15 weight part after the solidifying agent mixing of 5 weight parts is uniformly mixed; Adopt notch cuttype heating mode, be warmed to 90 degree of plus-pressures 65 kilograms to stop 8 minutes, uniform compaction, promote temperature again to 120 degree of stops 10 minutes, continue to be warmed to 160 degree stop 30 minutes after, have a power failure after being cooled to room temperature and take out in a mold, repair through roasting, polishing the sheet material that interim bridge formation is made on surface.
Further, described carbon fiber is 40 weight parts, and flexible epoxy vinyl ester resin is 43 weight parts, and solidifying agent is 5 weight parts, and nano-scale carbon filamentary material is 12 weight parts.At interim bridge formation sheet material two ends, fixed connecting piece is installed after making interim bridge formation sheet material, existing mode of connection can be adopted to be fixedly connected with by two blocks of interim bridge formation sheet materials.Its manufacturer's standard strictly by country about the specification of quality of interim bridge of boats bridge and related standards carry out testing improvement after, a kind of use of formation carbon-fibre composite manufacture substitutes the interim bridge formation sheet material that bridge is built bridge for crossing the river temporarily.
After adopting such design, the present invention at least has the following advantages:
Adopt carbon-fibre composite, intensity is high, quality is light, have both again the soft workability of textile fibres, be easy to compound, anisotropy, design freedom is large, the design of kinds of schemes can be carried out, with satisfied different goods to the requirement of its performance, can strengthen with other blending in of fibers, learn from other's strong points to offset one's weaknesses, bring out the best in each other, make its reinforced effects more remarkable: closely obtain high strength, high-modulus, high-tension plate, volume weight about 1.9, intensity is more than 60 times of steel, its Young's modulus be 4 times of aluminium alloy with first-class.This density of material is little, and quality is light; High-modulus, high rigidity, high strength, Qiang Erjian.Its maximum feature is that Young's modulus is high, the large twice of antitypy energy force rate steel is many, tensile strength 30-40T/cm2pa, and proportion is less than 1/4th of steel, larger than iron and steel 16 times of plateau modulus, the satellite support that only 3.6kg is heavy, but can bear the load that 9000ks is heavy, thermal expansivity is little, dimensional stabilizing, antifatigue, long service life; Self-lubricating, wear-resistant; Energy-obsorbing and damping, having excellent attenuation function to vibration, is the ideal material for the manufacture of pontoon bridge that any other material cannot match in excellence or beauty.
Interim bridge formation sheet material of the present invention also can be applicable to the field such as manufacture, engineering structure of sports, building structure, naval vessels, shipping industry, freight container, flying instrument.
Embodiment
The invention provides a kind of interim bridging materials, its preparation method is: be first put into shaping for the carbon fiber knit of 40 weight parts in mould, is poured in mould together with the weight part of flexible epoxy vinyl ester resin 43 nano-scale carbon filamentary material of interpolation 12 weight parts after the solidifying agent mixing of 5 weight parts is uniformly mixed; Adopt notch cuttype heating mode, be warmed to 90 degree of plus-pressures 65 kilograms to stop 8 minutes, uniform compaction, promote temperature again to 120 degree of stops 10 minutes, continue to be warmed to 160 degree stop 30 minutes after, have a power failure after being cooled to room temperature and take out in a mold, repair through roasting, polishing the sheet material that interim bridge formation is made on surface.
At interim bridge formation sheet material two ends, fixed connecting piece is installed after making interim bridge formation sheet material, existing mode of connection can be adopted to be fixedly connected with by two blocks of interim bridge formation sheet materials.Its manufacturer's standard strictly by country about the specification of quality of interim bridge of boats bridge and related standards carry out testing improvement after, a kind of use of formation carbon-fibre composite manufacture substitutes the interim bridge formation sheet material that bridge is built bridge for crossing the river temporarily.
The above; it is only preferred embodiment of the present invention; not do any pro forma restriction to the present invention, those skilled in the art utilize the technology contents of above-mentioned announcement to make a little simple modification, equivalent variations or modification, all drop in protection scope of the present invention.
