Description
Technical field
The present invention relates to a kind of fibre bundles, especially with regard to a kind of carbon fibre tow forming device.The present invention is separately closed
In carbon fiber wire beam forming method.
Background technique
Material extruding first can first be carbonized, referring to Fig. 1, being first intended to by the traditional forming of carbon fibre tow at filiform
The fibre bundle of carbonization is by a dehumidifying stage 110, and the dehumidifying stage 110 includes one first vacuum dehumidifying step 111, the
One dew point dehumidifying step 112, the second vacuum dehumidifying step 113 and the second dew point dehumidifying step 114, fibre bundle is by aforementioned
The dehumidifying stage 110 after, will remove fibre bundle in moisture, reached the purpose of dry fiber tow；
The fibre bundle carried out for one first heating period 120 after the dehumidifying stage 110 is dry, then by fibre bundle,
The heating period 120 be resistance-type heat or gas heating, and first heating period 120 include a pre- heating step 121,
One first heating stepses 122 and one second heating stepses 123, which is to be heated to fibre bundle by room temperature
100 DEG C, which is that fibre bundle is heated to 260 DEG C by 100 DEG C, which is will be fine
It ties up tow and is heated to 500 DEG C by 260 DEG C, which can make fibre bundle stabilization.
The wire stock after carbonization is given into starching again, drying after immersing in resin makes wire stock external sheath have one
Layer resin, and resin total amount accounts for the 5%~6% of wire stock, prevents wire stock to be mutually stained with whereby glutinous, will finally be coated with again
The wire stock of resin is wound, for subsequent carbonization use.
Then, by fibre bundle one second heating period 130 of progress of stabilization, which includes
One third heating stepses 131 and one the 4th heating stepses 132, the third heating stepses 131 are to heat fibre bundle by 500 DEG C
To 1000 DEG C, and the 4th heating stepses 132 are then that fibre bundle is heated to 1500 DEG C by 1000 DEG C, second heating period
130 are that fibre bundle is carbonized.
Finally, the fibre bundle of carbonization is carried out a third heating period 140, which then includes one
5th heating stepses 141, the 5th heating stepses 141 are that fibre bundle is heated to 3000 DEG C by 1500 DEG C, make fibre bundle
Graphitization.
Carbon fibre tow starching after the completion is spare, and can be glued according to different needs, such as: utilize resin
Film laminating simultaneously heats carbon fibre tow, so that resin film is attached on carbon fibre tow or is immersed carbon fibre tow and sets
In rouge；Whereby, enable carbon fibre tow according to different usage modes, glue in different ways.
However, aforementioned fibre bundle entirety carbonization time is tediously long, and its first heating period, the second heating period and this
Three heating periods are heated in a manner of resistance-type heating, begin to warm up fibre bundle by outside, and fibre bundle is by outer
Portion is heated and is carbonized since outside, begins to complete carbonization via fibre bundle after multiple heating stepses, but because fibre bundle is
It is carbonized since outside, causes the inside carbonizing degree of fibre bundle different from outside, cause fibre bundle carbonization uneven, and because
It must slowly heat up for the heating process of fibre bundle, it is small to last 5~10 from the arrival third heating period in dehumidifying stage 110
When, it so that fibre bundle is completed graphitization, causing aforementioned fibre bundle carbonisation, there are when carbonizing degree unevenness and carbonization
Between tediously long problem.
In view of this, making fibre it is necessory to provide a kind of carbon fibre tow forming device and carbon fiber wire beam forming method
It is uniform carburized to tie up tow, and shortens carbonization time.
Summary of the invention
The present invention provides a kind of carbon fibre tow forming device and carbon fiber wire beam forming method, it is therefore intended that makes fiber filament
Beam can be uniform carburized, and it is spare to glue retracting.
It is another object of the present invention to shorten fibre bundle entirety carbonization time.
To solve foregoing problems, the present invention is a kind of carbon fiber wire beam forming method, includes:
One dehumidifying step, will the drying of an at least fibre bundle；
Temperature is heated to by one induction heating step by an at least fibre bundle in the method for induction heating from room temperature
500 DEG C, stabilize an at least fibre bundle；
Temperature is heated to 1000 from 500 DEG C by an at least fibre bundle in a manner of microwave by one first microwave step
DEG C, so that an at least fibre bundle is carbonized；
Temperature is heated to by one second microwave step by an at least fibre bundle in a manner of microwave from 1000 DEG C
1500 DEG C, it is graphitized an at least fibre bundle；
One laser step makes temperature be heated to 3000 DEG C from 1500 DEG C, by an at least fibre bundle in a manner of laser
Irradiation, is graphitized the inside of an at least fibre bundle uniformly；
The surface of an at least fibre bundle is formed a plurality of pit-holes by one roughening treatment step；
One ester moulding step is provided a resin and is attached to fibre bundle surface in a manner of high pressure, and resin again via
A plurality of pit-holes on surface enter the inside of an at least fibre bundle, are full of the surface and inside of an at least fibre bundle
Resin；
Half cures forming step, controls the temperature and pressure of an at least fibre bundle environment, makes an at least fiber
The resin of tow surface and inside is in semi-curing state.
Since an at least fibre bundle is with microwave side when by the first microwave step and the second microwave step
Formula heating, makes an at least fibre bundle thermally equivalent, and an at least fibre bundle passes through the laser step, and laser can
It is irradiated to the inside of an at least fibre bundle, the inside of an at least fibre bundle is evenly heated also, makes the present invention
The purpose for keeping fibre bundle uniform carburized can be reached.
It is subsequent through swashing again because the first microwave step and the second microwave step of the invention is heated with microwave mode
Light and semi-curing step, overall process are only needed by about dozens of minutes, the time spent by mutually more conventional heating method, this hair
It is bright to shorten fibre bundle carbonization time, it not only saves the energy and more reaches the effect of reducing cost.
