Description
Technical field
The present invention relates to carbon fibre composite application study technical fields, enhance more particularly, to a kind of double composite materials
Ring manufacture craft.
Background technique
During developing green energy resource, energy saving energy storage is a kind of developing direction of reasonable energy utilization, accumulated energy flywheel
A direction exploring and developing always now both at home and abroad, use carbon fibre composite as reinforcing material also increasingly
Extensively, carbon fibre composite has high intensity, high-modulus, designability, is applied not only to the production of accumulated energy flywheel, including fly
The position that magnet steel is bonded in wheel shaft carries out the enhancing ring of enhancing production using carbon fibre composite.
Traditional method is that winding production one is less than the carbon fiber annulus of 0.1~0.2mm of shaft diameter (i.e. on core model
Enhance ring), after curing molding, is demoulded, further according to the principle expanded with heat and contract with cold, the portion of magnet steel will be studded with using the method for cold set
It after the shaft of position is cooled to -60~-70 DEG C, is sleeved on carbon-fibre reinforced in shaft, because of heat after shaft is restored to room temperature
As soon as swollen have a magnitude of interference to carbon-fibre reinforced, carbon-fibre reinforced in this way to have a compression to shaft；This method
Studding with the surface smoothness of magnet steel and circularity to shaft has higher requirement, installs a metallic sheath additional generally outside magnet steel,
Processing cost is higher.
Summary of the invention
The present invention calculates design in order to realize the production carbon-fibre reinforced purpose of double-layer composite material, by composite material,
Directly successively successively decrease to the position progress hightension for being bonded with magnet steel in shaft by design requirement and winds glass fibre and carbon fiber
Process.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of double composite material enhancing ring manufacture crafts, comprising:
The shaft workpiece for being bonded with magnet steel wound will be needed to be ready to, it is solid with bolt in the position two sides that needs are wound
Dingan County fill aluminium alloy retaining ring, retaining ring diameter than winding after carbon fiber outer diameter it is 2mm big, be fixed on shaft need to wind it is compound
The position two sides of material, retaining ring coat release agent in advance, carry out burr, flange etc. to the surface that winding position has bonded magnet steel and lack
Sunken cleaning；
Glass fibre is adjusted into winding position onto clamping shaft by steeping vat and straining pulley, sets yarn
Width is wrapped in the outer surface of the magnet steel bonded in shaft, twines to design thickness；
After having twined glass fibre, continue wind carbon fiber, can according to the carbon fiber of the different intensity and modulus of design alternative,
It is wide to set yarn, design winding layer number winds carbon fiber outside glass fibre；
The shaft for winding the workpiece of glass fibre and the double composite materials of carbon fiber is placed in heating device, lower heating is rotated
Then the glue for removing surface exudation carries out rotation and carries out precuring, curing process；
Workpiece is taken out after cooling, removes retaining ring, removes the burr of two sides, and production obtains double composite material enhancing rings.
By two kinds of materials of glass fibre and carbon fiber under conditions of hightension, it is directly wound in shaft and studs with magnetic material
Position on, double-layer composite material after curing molding is carbon-fibre reinforced to maintain certain prestressing force to shaft.Due to turning
Axis is worked in the state of high speed rotation, and magnetic material is fixed in shaft by the method for bonding, in the work of centrifugal force
Under, magnetic material has outside power, and using having, prestressed two-layer compound is carbon-fibre reinforced to can be constrained fixed magnetic material
Material, prevents it from dispersing when rotating at high speed and falls off.
If directlying adopt carbon fiber to be wound, can be solidified into since composite material requires heat to certain temperature
More than coefficient of thermal expansion differences an order of magnitude of type, metal material and carbon fibre material, because of the reason of expanding with heat and contract with cold, solidification cooling
It will appear the carbon-fibre reinforced prestressing force to shaft afterwards to decline, or even gap occur, be not achieved and the magnet steel of shaft is applied in advance
The effect of stress；Its thermal expansion coefficient of glass fibre is slightly less than the thermal expansion coefficient of metal material, therefore, using elder generation in shaft
It studs with and directly carries out high-strength glass fibre hightension winding on the position of magnetic material, then carry out hightension winding with carbon fiber,
Double-layer composite material after curing molding is carbon-fibre reinforced to can achieve design requirement.
Further, glass fibre uses high-strength S4 glass fibre and/or 12~24K glass fibre, and glass fibre is twining
Around when, it is 90 ± 1N that winding, which starts tension, and one layer of tension of every winding subtracts 1~2N.Each layer of fiber is to internal layer in winding process
Fiber have a pressure, so that inner fiber is had certain relaxation, according to calculate setting successively subtract tension, after winding,
The tension of each layer of fiber is all almost the same, and composite material entirety stress intensity is highest after solidification.If tension force is not
Uniformly, the fibrous layer stress having in stress is big, and some fibrous layer stress are small, and fibrous layer is caused to defeat in detail, and cannot reach multiple
The best mechanics intensity effect of condensation material.Winding after the completion of formed glass layer with a thickness of 1~1.5mm.
Further, using T700 and/or 12k, tensile strength is wound in 4500~5000MPa carbon fiber, carbon fiber
For dimension in winding, it is 160 ± 1N that winding, which starts tension, and one layer of tension of every winding subtracts 2~3N, carbon fiber stress is made to be in one etc.
Stress state reaches best.
Further, winding after the completion of formed double composite layers with a thickness of 5-6.5mm.
Further, workpiece one end is clamped on the rotary chuck of heating device, and the other end is withstood on heating device tail top
On the centre bore of shaft.
Further, workpiece 20~22min of rotation processing at 90 DEG C, after workpiece surface glue is removed, then at 90 DEG C
Precuring 3~4h, 110 DEG C of -130 DEG C of 4~5h of curing process are cooled to room temperature, solidification terminates with heating device.
Compared with prior art, the present invention can simplify technique using double-layer composite material is carbon-fibre reinforced, reduce system
This is caused, the double-layer composite material enhancing ring after curing molding can achieve design requirement.
