Abstract
The invention relates to a method for manufacturing a carbon fiber arm support for a concrete pump truck. The carbon fiber arm support is provided with a hollow mandrel; the surface of the mandrel is hollowed out; a layer of vacuum film is covered on the surface of the mandrel; raw materials for manufacturing the carbon fiber arm support are laid on the surface of the vacuum film; an upper die and a lower die are combined on the mandrel; the combined position of the upper die and the lower die is fastened by bolts; the upper die and the lower die are coated by a vacuum film, and both ends of the vacuum film are sealed with both ends of the vacuum film on the mandrel; an air exhaust hole is formed on the vacuum film; and the whole die is put into a hot-press tank, is pressurized by compressing air and is heated, cured and molded by an electric heating tube. The carbon fiber arm support for the concrete pump truck processed by the method can fully exert the advantages of high specific strength, high specific modulus, fatigue resistance and corrosion resistance of carbon fiber reinforced epoxy resin composite materials so as to obtain superior-performance arm supports for the concrete pump truck and reduce 40 to 60 percent of weight of the arm support. Meanwhile, the method can be used in the fields of arm supports for fire trucks, suspension arms for hoisting equipment, power transmission, communication wires and poles and the like.
Description
Technical field
The present invention relates to technical field of composite materials, specifically a kind of method manufacturing carbon fiber arm support for concrete pump truck.
Background technology
As everyone knows, jib is one of topmost critical component of concrete mixer, and its security, reliability and advance are the keys determining pump truck core competitiveness.At present, pumping vehicle arm rack many uses high strength steel manufactures, and weight is comparatively large, requires higher to vehicle frame, chassis, and oil consumption is comparatively large, and mobility is poor; Meanwhile, under pump truck working condition is in Under Dynamic Load all the time, between each parts of jib structure, also there is coupling, easily because local deformation, problems of crack appear in fatigue rupture; In addition, the working environment of pump truck is comparatively severe, easily etching problem occurs.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of method manufacturing carbon fiber arm support for concrete pump truck, utilize the carbon fiber arm support for concrete pump truck of the method manufacture have lightweight, intensity is high, good rigidly, endurance, erosion-resisting feature.By scientific design, reasonable construction, gives full play to that carbon-fibre reinforced epoxy resin composite material specific strength is high, specific modulus is large, endurance, erosion-resisting advantage, and then obtain the concrete pump truck arm of superior performance.
The technical solution adopted for the present invention to solve the technical problems is: a kind of method manufacturing carbon fiber arm support for concrete pump truck, be provided with core, for hollow structure, surface hollow-out, mandrel surface paving covers one deck vacuum diaphragm, the raw material manufacturing carbon fiber arm support are laid in vacuum diaphragm surface, patrix and counterdie are combined on core, patrix and counterdie die-closed position bolted, patrix and counterdie coated by vacuum diaphragm, vacuum diaphragm two ends on two ends and core are sealed, vacuum diaphragm is provided with aspirating hole, autoclave put into by whole mould, utilize pressurized with compressed air, carry out being heating and curing with electric heating tube shaping.
The invention has the beneficial effects as follows, carbon-fibre reinforced epoxy resin composite material specific strength is high, specific modulus large, endurance, erosion-resisting advantage to utilize the method to give full play to, and then produce the concrete pump truck arm of superior performance, can make jib loss of weight 40% ~ 60%, this invention simultaneously also may be used on the arm of such as fire fighting truck jib, crane gear, transmission of electricity and the field such as order wire bar.
