Abstract
The invention relates to a method for manufacturing a carbon fiber arm support for a concrete pump truck, which comprises the following steps of: arranging a hollow core mold, laying a raw material for manufacturing the carbon fiber arm on the external surface of the core mold, coating the exterior of the raw material by using a vacuum film, sealing both ends of the vacuum film on both ends of the core mold, arranging air exhaust holes on the vacuum film, putting the entire mold in an autoclave, pressurizing by using compression air, and curing to form by using an electric heating tube to heat. The carbon fiber arm support for a concrete pump truck, processed by using the method, fully exerts the advantages of high specific strength, large specific modulus, fatigue resistance and corrosion resistance of a carbon fiber reinforced epoxy resin composite material, so that the pump truck arm support has excellent performance, and the weight of the arm support can be reduced by 40-60%. Meanwhile, because no outer mold is used in the invention, the investment to molds, tooling and equipment is greatly reduced, and the product design can be changed conveniently. Meanwhile, the method can also be applied to the fields of fire truck arm supports, suspension arms of hoisting equipment, transmission poles, communication poles and the like.
Description
Technical field
The present invention relates to technical field of composite materials, specifically a kind of method of making the automobile-used carbon fiber jib of concrete pump.
Background technology
As everyone knows, jib is one of topmost critical component of concrete mixer, and its security, reliability and advance are the keys of decision pump truck core competitiveness.At present, pumping vehicle arm rack uses the high strength steel manufacturing more, and weight is bigger, is had relatively high expectations in vehicle frame, chassis, and oil consumption is bigger, and mobility is relatively poor; Simultaneously, pump truck operation operating mode is under the dynamic load effect all the time, also exists coupling between each parts of jib structure, easily local deformation, problems of crack occur because of fatigue rupture; In addition, the working environment of pump truck is more abominable, and etching problem easily takes place.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of method of making the automobile-used carbon fiber jib of concrete pump, utilize the automobile-used carbon fiber jib of concrete pump of this method manufacturing have in light weight, intensity is high, good rigidly, endurance, anticorrosive, characteristics that investment is little.By science design, reasonable construction, give full play to that carbon-fibre reinforced epoxy resin composite material specific strength height, specific modulus are big, 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 of making the automobile-used carbon fiber jib of concrete pump, be provided with core, be hollow structure, the raw material of making the carbon fiber jib are laid on the core outer surface, and the raw material outside coats with vacuum diaphragm, the sealed at both ends two ends at core of vacuum diaphragm, vacuum diaphragm is provided with aspirating hole, entire die is put into autoclave, utilizes pressurized with compressed air, with the electric heating tube moulding that is heating and curing.
The invention has the beneficial effects as follows, utilize that this invention can give full play to that carbon-fibre reinforced epoxy resin composite material specific strength height, specific modulus are big, endurance, erosion-resisting advantage, and then produce the concrete pump truck arm of superior performance, can make jib loss of weight 40%～60%.This invention has simultaneously significantly reduced the input of mould, frock and equipment owing to do not use external mold, can also change product design easily.This invention simultaneously also may be used on the fields such as arm, transmission of electricity and order wire bar such as fire fighting truck jib, crane gear.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1, procedure schematic diagram of the present invention.
1. cores among the figure 2. are used to make the carbon fiber prepreg of the automobile-used carbon fiber jib of concrete pump, 3. vacuum diaphragm, 4. autoclave, 5. aspirating hole, 6. air admission hole.
The specific embodiment
As shown in Figure 1, present embodiment is provided with core 1, carbon fiber prepreg 2 shops that are used to make the automobile-used carbon fiber jib of concrete pump are overlying on the outer surface of core 1, carbon fiber prepreg 2 is outside with vacuum diaphragm 3 coatings, vacuum diaphragm 3 sealed at both ends two ends at core 1, vacuum diaphragm 3 is provided with aspirating hole 5, and entire die is put into autoclave 4, and autoclave 4 is provided with air admission hole 6.Vacuum diaphragm 3 inner airs are all discharged by aspirating hole 5, form vacuum, after the step-down test passes, import compressed air through air admission hole 6 and pressurize, with the electric heating tube moulding that is heating and curing.
