For realizing above object, the utility model is achieved through the following technical solutions:
The high bearing rod of composite, is characterized in that, comprises metal cylinder; Described metal cylinder external surface is coated with the first fiber-reinforced plastic layer successively.
Preferably, described the first fiber-reinforced plastic layer is one or more reinforced plastics in carbon fiber, metallic fiber, carbon fiber, boron fibre, asbestos fibre, metallic fiber, aramid fiber, Orlon fiber, polyester fiber, nylon fiber, vinylon fiber, polypropylene fibre, polyimide fiber, cotton fiber and sisal hemp.
Preferably, described the first fiber-reinforced plastic layer is that the first fiber reinforcement plastic stockline or the first fiber reinforcement plastic material strip are wound in described metal cylinder external surface formation successively.
Preferably, described the first fiber-reinforced plastic layer outer surface is also provided with the second fiber-reinforced plastic layer.
Preferably, described the second fiber-reinforced plastic layer is fiberglass reinforced plastics layer or whisker reinforced plastic layer.
Preferably, described the first fiber-reinforced plastic layer is carbon fibre reinforced plastic layer; Described the second fiber-reinforced plastic layer is fiberglass reinforced plastics layer.
Preferably, described the second fiber-reinforced plastic layer is that the second fiber reinforcement plastic stockline or the second fiber reinforcement plastic material strip are wound in described metal cylinder external surface formation; Described many first fiber reinforcement plastic stocklines or the first fiber reinforcement plastic material strip are wound in described metal cylinder external surface successively.
Preferably, described metal cylinder is provided with mesopore.
Preferably, described metal cylinder external surface is provided with insulating coating, and described insulating coating is arranged between described metal cylinder external surface and described the first fiber-reinforced plastic layer.
Preferably, described insulating coating is resinous coat.
Preferably, described metal cylinder external surface is waveform.
The utility model is especially suitable as in airborne vehicle, the high bearing rod of composite of using as airborne vehicle.
Fiberglass reinforced plastics in the utility model is also referred to as fiberglass.
The high bearing rod of composite in the utility model, take full advantage of metal material ductility and the performance such as the designability of material homogeneity, composite and fatigability, make it not only can bear temporary impact and long dither, also there is good resistance to elevated temperatures and hot strength, simultaneously fiberglass strengthens overcoat and has good physical property, so being of wide application of this product.The utility model arranges insulating coating at metal cylinder external surface, can prevent the galvanic corrosion problem between metal cylinder and the first fiber-reinforced plastic layer.When the first fiber-reinforced plastic layer is carbon fibre reinforced plastic layer, its impact resistance is poor, is subject to the impact of external environment, and therefore the outer surface at carbon fibre reinforced plastic layer arranges fiberglass reinforced plastics layer again, can strengthen impact resistance of the present utility model.Compare with all-metal load connecting rod, in the situation that reach identical every mechanical index, this utility model has the safety coefficient of obvious weight advantage and Geng Gao, and this also means that this utility model will have bright application prospect in fields such as Aero-Space, heavy-duty machinery, automobiles.Compare with all-metal construction, in the situation that reach identical every mechanical index, use the utility model can alleviate 30% weight.Through experimental examination, the high bearing rod of composite in the utility model bears the ability of temporary impact higher than the bar of simple metal material.
Accompanying drawing explanation
Fig. 1 is the radial section schematic diagram of embodiment 1.
Fig. 2 is the axial cross section schematic diagram of embodiment 2.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail:
Embodiment 1
As shown in Figure 1, the high bearing rod of composite, comprises metal cylinder 1.Metal cylinder 1 can adopt various metal materials, as metals such as steel, iron, alloys.Metal cylinder 1 is provided with mesopore 11.Metal cylinder 1 outer surface is coated with insulating resin layer (not shown).Insulating resin layer surface is coated with the first fiber-reinforced plastic layer 2.Insulating resin layer can separate metal cylinder 1 and the first fiber-reinforced plastic layer 2 insulation.The first fiber-reinforced plastic layer 2 is one or more reinforced plastics in carbon fiber, metallic fiber, carbon fiber, boron fibre, asbestos fibre, metallic fiber, aramid fiber, Orlon fiber, polyester fiber, nylon fiber, vinylon fiber, polypropylene fibre, polyimide fiber, cotton fiber and sisal hemp.The first fiber-reinforced plastic layer 2 is that the first fiber reinforcement plastic stockline or the first fiber reinforcement plastic material strip are wound in described metal cylinder external surface 1 formation; Described many first fiber reinforcement plastic stocklines or the first fiber reinforcement plastic material strip are wound in described metal cylinder 1 outer surface successively.The first fiber-reinforced plastic layer 2 outer surfaces are also provided with the second fiber-reinforced plastic layer 3.The second fiber-reinforced plastic layer 3 is fiberglass reinforced plastics layer or whisker reinforced plastic layer.Described the second fiber-reinforced plastic layer 3 is that the second fiber reinforcement plastic stockline or the second fiber reinforcement plastic material strip are wound in described the first fiber-reinforced plastic layer 2 outer surfaces formation successively.In example as shown in the figure, described the first fiber-reinforced plastic layer 2 is carbon fibre reinforced plastic layer; Described the second fiber-reinforced plastic layer 3 is fiberglass reinforced plastics layer.
Embodiment 2
As shown in Figure 2, the difference of the present embodiment and embodiment 1 is, the outer surface 12 of metal cylinder 1 is waveform.Described metal cylinder external surface is waveform.Described waveform shape extending axially along metal cylinder 1.The first fiber-reinforced plastic layer 2 and the second fiber-reinforced plastic layer 3 all adapt to the waveform shape of metal cylinder 1 outer surface 12.All the other structures are identical with embodiment 1.
Being especially suitable as in airborne vehicle in the utility model, the high bearing rod of composite of using as airborne vehicle.
