Abstract

The invention relates to a kind of unsealed method and apparatus for reinforced fiber beams and the manufacturing method for pre-preg material, I.e. to provide a method and an apparatus that can keep the reinforced fiber beam unsealed by aligning multiple single filament of reinforced fiber beam; or dragging-alignment parallel the multiple reinforced fiber beams to be bent on multiple rollers; and while carrying out the unsealing process through the roller and during producing pre-preg material by immersing the unsealed reinforced fiber beams in the resin, at least one of the rollers will vibrate along the axial direction to perform the unsealing process on the reinforced fiber beam. And, without vibrating the roller right behind the vibrating roller, the reinforced fiber beams are pressed on the peripheral surfaces of the vibrating roller; then, the unsealed reinforced fiber beams are contacted on the peripheral surface without the vibrating roller by more than twice of the contact length in the vibrating rollers. By this invention, the unsealing process can stabilize the reinforced fiber beams with almost no napping effect so as to get uniform and thinner reinforced fiber sheet; and employing the uniform and thinner reinforced fiber sheet to produce good quality, non-crack, uniform and thinner pre-preg material.

V. Description of the invention (27) Before introducing the vibrating freely rotating roll 17, first heat the carbon fiber bundle 12 to 50 ° C ~ 180 ° C, preferably 70 to 140¾, the M soft mother should be applied to the carbon fiber After the sizing agent in the bundle 12, the roller 17 is then freely rotated by vibrating the vibration, so that the fiber opening effect can be further improved. Here, in the state where the heated temperature is less than 50t !, the sizing agent will become insufficiently softened ', so the fiber opening effect will be relatively small. In addition, when the heated temperature exceeds 180 ° C, the sizing agent will become excessively softened and become viscous, so the coefficient of friction will become higher * and it will rotate freely under this vibration The roll 17 is fluffed. In addition, in the aforementioned method for opening carbon fiber bundles * After the carbon fiber bundle 12 is opened, it is best to control the tension of the carbon fiber sheet (bundle) at a fineness of 1,000 per single filament (that is, , The fiber bundle is composed of 1,000 monofilaments), in the range of 0.05 ~ 0.80N. With this treatment, in the resin impregnation operation, K can suppress the excessive impregnation of the resin in the carbon fiber sheet * K so that the resin does not remain on the carbon fiber sheet, and a good surface quality can be obtained Prepreg embryo. When the tension is less than 0.05N per 1,000 filament fineness, when the pressure treatment is performed during the impregnation operation, the uniformly soled carbon fiber bundle 12 travels and becomes chaotic. At the same time, the distance between the carbon fiber bundles will also become chaotic. Therefore, when the prepreg is treated, it will become the cause of the cracking. When the tension exceeds 0.8N per green fineness, once the fiber opening process is performed, the drawn carbon fiber sheet will once again cause many single wires of the carbon fiber sheet to be bundled due to the effect of tension.

Description of the invention (19) First of all, the reinforcing fiber bundle 2 is best to be wound when the reinforcing fiber bundle 2 is wound out, and becomes 0.1 ~ The winding process of the reinforcing fiber bundle 2 is performed in a state within a range of 5N. When the tension becomes too high, it is not conducive to fiber opening treatment; on the contrary, when the ... tension becomes too low, the fiber bundle will become meandering. And, the smaller the traveling speed of the reinforcing fiber bundle 2 is, the more favorable the K is to lengthen the contact time between the vibration rolls 5 a, 5 b and the vibration-free rolls 7 a, 7 b; even during the travel In a state where the speed becomes larger, it is possible to appropriately cope with the situation by increasing the number of the vibration rolls and the vibration-free rolls. ^::: ^ The vibration frequency of the vibrating rollers 5 a and 5 b is in the range of 1 to 1 0 0 Η ζ. The larger the frequency is, the more ideal it is; however, if it is restricted by the mechanism, it is 3 to 30Hz, even 5 ~ 20Hz, can fully meet the requirements.

Description of the invention (20) Here, below the freely rotating roll 15 for introduction, the heating source 16 is provided, and the carbon fiber bundle is heated by K 1 2 Then, the vibration free rotation roll 17 and the vibration-free free rotation roll 18 are paired; however, here ~, ---, there are 3 pairs of vibration free rotation rolls 17 and no vibration By rotating the rollers 18, the carbon fiber bundles 12 are passed through the roller groups, and the carbon fiber bundles 12 are opened. At the exit of the roll set, a freely rotating roll 19 for opening the fiber opening device is provided. On the downstream side of the free-spinning roller 19 for the opening of the fiber opening device, a tension applying roller 20 is provided; therefore, after the carbon fiber bundle 12 is opened, the carbon fiber bundle can be appropriately increased. The tension in 1 2. The carbon fiber bundle 12 sent from the tension applying roller 20 passes through the freely rotating roller 21 used for introduction of the resin film. Starting from both sides of the carbon fiber bundle 12, the lower resin film 22K and the upper A resin film 23 is superposed on the sheet-like carbon fiber bundle 12. The overlapping body is heated by heating means 2 4; then the overlapping body is pressurized from both sides of the overlapping body by the impregnating rolls 25, so that the resin is impregnated into the carbon fiber bundle 1 2 Inside, and formed into a prepreg lamella. The various processes in the manufacture of the aforementioned prepregs will be explained in more detail. In the manufacturing of the aforementioned prepreg, in the apparatus for fiber opening treatment of the carbon fiber bundle 12 composed of 10 or more carbon fibers at least parallel to each other, the system is: (a ) The device is provided with a combination of 2 to 10 sets of roller groups; and these roller groups are free to rotate and vibrate along the axis of the rollers.

Description of the invention (2 1) Roller 1 7, and no vibration (B) In this device, the diameter of the vibration free rotation roll 17 is 20 to 50 mm, and the vibration free rotation roll 1 8 The diameter ranges from 50 to 120. In addition, between the freely rotating rolls 17 and 15 of the freely rotating rolls 8 without vibration * so that the carbon fiber bundle 12 does not touch the two The distance between each roll 1 7 and 18 becomes between 1 0 and 1 Within the range of 0 0 mm, therefore, between each of the free-running rollers 17 with vibration and the free-running rollers 18 without vibration, each free-running roller 17 with vibrations and free-running rollers 18 with vibrations are also arranged. The carbon fiber bundle 12 is caused to alternately pass through the vibration-free rotating roll 17 and the vibration-free free rotating roll 18. Here, the number of combinations of the vibration-free rotating rolls 17 and the vibration-free free-rolling rolls 18 provided after the vibration-free rotating rolls 17 are two to ten sets, but it is best There are 3 groups to 8 groups. In the combined state of one group, the fiber opening effect of the traveling carbon fiber bundle 12 at the speed of K 5 to 30 m / min can hardly be obtained. In addition, even in the combination state of 11 sets of K, the fiber opening effect of the carbon fiber bundle 12 cannot be improved, but the number of rolls will increase, and the equipment cost will increase, which is not suitable. The diameter of the freely rotating roll 17 of this vibration is set to be 20 to 50, but it is preferable. When the diameter of the freely rotating roll 17 of this vibration (less than 20 coffee), the contact angle of the carbon fiber bundle 12 will become smaller, so r. \ Even if the freely rotating roll 17 of this vibration vibrates, It is almost impossible to obtain the fiber opening effect of the carbon fiber bundle 12. In addition, when the vibration of the free-rolled rolled paper is in accordance with the Chinese National Standard (CNS) A4 specification (210X 297 mm) _ 0, ------- -; --- ^ 装 ------ Order ----- „-* ^ 1 (Please read the notes on the back before filling out this page) A7 B7 Economy.% Printed by the Central Consumer Labeling Cooperative Fifth, the description of the invention (22) When the diameter of the roller 17 is more than 50 brains, the contact length becomes longer, which causes friction easily, and the problem caused by the fluffing phenomenon occurs + Moreover, The diameter of the vibration-free freely rotating roll 18 is set to 50 to 120 legs, but it is preferably 60 to 100. It is because the vibration freely rotates the roll 18 and maintains the fixed position. At the same time, the carbon fiber bundles 12 are rotated freely at the vibration, and the carbon fiber bundles 12 are opened. Therefore, it is better to lengthen the contact length between the carbon fiber bundle 12 and the vibration-free free rotation roll 18; in a state where the diameter of the vibration-free free rotation roll 18 is less than 50 brains, it is used to maintain The force holding the carbon fiber bundle will become smaller, so it cannot get enough fiber opening effect. In addition, even if the diameter of the freely rotating roller 18 without vibration exceeds 120 strokes, the required force to maintain the fixing is If the diameter of the vibration free rotation random roller 18 is 120 legs, sufficient maintenance power can be obtained, so it is not necessary to make the diameter of the vibration free rotation roller 18 more than 120 buds. Moreover, like this, it will also There is a problem that the cost of the equipment becomes high. The distance between the rolls without contacting the carbon fiber bundle 12 is set to 1 ~ 1 0 0 iinn, but it is preferably 2 ~ 7 0 nun In the state where the distance between the L rollers of each car without contacting the carbon fiber bundle 12 is at least 10 coffee, the vibration of the freely rotating roller 17 causes the carbon fiber bundle 1 2 on the march At the same time, the distance between the carbon fiber bundles 12 and 12 will also become disordered. Therefore, when the prepreg is treated, it will cause the cracks. In addition, when it is between the rolls, When the distance between the carbon fiber bundle 12 and the carbon fiber bundle 12 does not exceed 100 0 imii, the amplitude of the vibration of the carbon fiber bundle 12 will become smaller, so there is almost no paper paper scale applicable to the Chinese National Standard (CMS).

It has ridges; with this structure, a more uniform and thinner carbon fiber bundle sheet can be obtained. Generally, even if it is a carbon fiber bundle of an untwisted wire sold in the market, in fact, the twist remains in the carbon fiber bundle itself. When this twisted wire is present, the carbon fiber bundles will move left and right, and the gap between the carbon fiber bundles will be skewed. Therefore, when using this carbon fiber bundle to make a prepreg embryo, * there will be cracks „There is a problem with the meaning of __. Therefore, if it is applicable to the paper size of its surface. National Standard (CNS) A4 (210X297 mm) Λ Λ A 7 B7 V. Description of the invention (24) With a freely rotating roll with a ridge, the carbon fiber bundle can be held and fixed at the ridge portion, and the movement along the axis of the roller caused by the twist can be stopped, so it can be kept constant. To make the prepreg blank without cracks. In order to make the carbon fiber bundle 12 not contact the surface of the roll as much as possible, the height (t) of the aforementioned protrusion 31 becomes The height exceeding (1 / cos (θ / 2) — 1), and the angle (θ) between the protrusions is in the range of 5, 50 °, but the angle between the protrusions is preferably It is within the range of U 1 ～ 40 °. When the angle (Θ) between 3 and 1 is less than 5 °, the distance between the protrusions becomes too narrow, which weakens the force that stops the twisting; as shown in Figure 4 (B), When the angle (Θ) between the adjacent ridges 31 exceeds 50 °, the curvature of / in the protrusion portion a will increase, and the single line of the carbon fiber bundle 12 will break, K and Fuzzing is prone to occur. Therefore, as shown in Fig. 4 U), the angle (Θ) between the protrusions must be set within an appropriate range, 5 to 50 ° ..

In addition, in the aforementioned opening device of the carbon fiber bundle, the vibration of the free \ rotating roller 17 and the iU frequency of the free rotating roller of the η vibration, "-* -------― *- ------- The systems are all the same; and the phase of the vibration of the freely rotating rolls of the η roots are each deviated from each other by 3 6 〇 / η °, and f moves, & gt Yousheng_ disperses and offsets the vibration of the fiber opening device of the entire carbon fiber bundle, so _ can maintain the durability of the device, and K and _M make the maintenance and maintenance costs become. In addition, among the rolls used in the aforementioned carbon fiber bundle opening device, it is preferable to make at least the vibration free rotation roll 17 and no vibration from the surface of at least two inches of the rotating roll 18 The surface thickness of the pear skin with a surface roughness of 3S to 20 S * is more desirable, and a surface roughness of 6 S to 16 S is more preferable. When the surface roughness becomes an upright state, the contact area of the carbon fiber bundle 12 to the roll surface will increase, so that a sizi ng agent is transferred to the roll surface, and the roll surface is contaminated. However, I am afraid that the single wire of the carbon fiber bundle 12 will be wound up, so that the single _ || of the carbon fiber bundle 12 will break, so it is also not appropriate. When the surface roughness exceeds 20S, the carbon fiber bundle 12 is easily damaged at the unevenness on the surface of the roll, and it becomes the cause of the fluffing phenomenon, so it is also not ideal. In addition, in addition to the vibrating free rotating roll 17K and the vibration-free free rotating roll 18, the surface roughness of the free rotating roll 15 for introduction and the free rotating roll 19 at the exit of the carbon fiber bundle opening device are also the most rough. It has become the same as the previous paper size applicable to the Chinese National Standard (CNS) A4 specification (210X 297 mm). 1 2 8 — (Please read the precautions on the back before filling this page.) Printed by the Standards Bureau Consumer Cooperative A7 B7 V. Description of Invention (2 6) Describe! Seed skin surface. In addition, when the combined number of the vibration free rotation roll 17 and the vibration-free free rotation roll 18 becomes relatively large, the carbon fiber bundle 12 cannot be easily passed between the rolls. The rollers on one side are raised and lowered, so that the carbon fiber bundle 12 can easily pass between the rollers. The fiber opening method of the carbon fiber bundle according to the present invention is to perform the fiber opening method of the carbon fiber bundle using a front fiber opening device; the carbon fiber bundle opening method * is to make the at least parallel to each other There are 10 carbon fiber bundles composed of 10 carbon fibers on K, M0.08 ~ 0.50m / s, for the method of traveling, and K is used to open the fiber. In the method of opening the carbon fiber bundle, the former is used. The fiber opening device of the carbon fiber bundle makes the amplitude of the free rotation of the vibration ft Guan 17 to be 1 to 50 nmi, preferably 1 to 30 mm, and the vibration frequency of the vibration free rotation roll 17 is 1 to 100 Hz. , Preferably 3 ~ 6 0 Η z. If it is more ideal, it is preferable that the amplitude is 3 to 2 5 mm and the vibration frequency is 5_ ^ 2 0Hz. In particular, the amplitude is preferably 3 to 2 0 and the vibration frequency is 5 to 1 7 Η z. Under the conditions, the fiber opening treatment is continuously performed. In the state where the amplitude is less than 1 mm and the vibration frequency is less than 1 Η ζ, even if the carbon fiber bundle 12 travels at a speed of M0.08 ~ 0.50ra / s, it is not easy to obtain the fiber opening effect; however, When the amplitude exceeds 50 legs and the vibration frequency exceeds 100 0 Η ζ, the vibration will cause the free-rotating roller to rub the carbon fiber bundle 12 due to vibration, so that the fluffing phenomenon easily occurs, so Not very appropriate. In the aforementioned method for opening carbon fiber bundles, the paper size of 12 carbon fiber bundles is in accordance with the Chinese National Standard (CNS) A4 specification (210 × 297 mm) (Please read the precautions on the back before filling this page).

V. Description of the invention (27) Before introducing the vibrating freely rotating roll 17, first heat the carbon fiber bundle 12 to 50 ° C ~ 180 ° C, preferably 70 to 140¾, the M soft mother should be applied to the carbon fiber After the sizing agent in the bundle 12, the roller 17 is then freely rotated by vibrating the vibration, so that the fiber opening effect can be further improved. Here, in the state where the heated temperature is less than 50t !, the sizing agent will become insufficiently softened ', so the fiber opening effect will be relatively small. In addition, when the heated temperature exceeds 180 ° C, the sizing agent will become excessively softened and become viscous, so the coefficient of friction will become higher * and it will rotate freely under this vibration The roll 17 is fluffed. In addition, in the aforementioned method for opening carbon fiber bundles * After the carbon fiber bundle 12 is opened, it is best to control the tension of the carbon fiber sheet (bundle) at a fineness of 1,000 per single filament (that is, , The fiber bundle is composed of 1,000 monofilaments), in the range of 0.05 ~ 0.80N. With this treatment, in the resin impregnation operation, K can suppress the excessive impregnation of the resin in the carbon fiber sheet * K so that the resin does not remain on the carbon fiber sheet, and a good surface quality can be obtained Prepreg embryo. When the tension is less than 0.05N per 1,000 filament fineness, when the pressure treatment is performed during the impregnation operation, the uniformly soled carbon fiber bundle 12 travels and becomes chaotic. At the same time, the distance between the carbon fiber bundles will also become chaotic. Therefore, when the prepreg is treated, it will become the cause of the cracking. When the tension exceeds 0.8N per green fineness, once the fiber opening process is performed, the drawn carbon fiber sheet will once again cause many single wires of the carbon fiber sheet to be bundled due to the effect of tension.

Description of the invention (28) The gap is 'the cause of the cracks' during the treatment of the prepreg ^. At the same time * in the impregnation operation * It will impede the resin from being impregnated in the carbon fiber sheet, and it may cause the un-impregnated portion to occur. As the carbon fiber bundles used in the present invention, polyacrylonitrile (polyacrylonitrile) and pitch (pitch) single-filament carbon fiber bundles of 3,000 to 100,000 can be used. In particular, the carbon fiber bundle having a monofilament fineness of 1 2,000 to 100,000 can be applied, and the uniform and relatively thin carbon fiber bundle that is not easily obtained by a common method can be obtained very effectively. Flakes. In the present invention, in the state where the carbon fiber bundles on the 10 (bundle) Ms are targeted, a considerable effect can be obtained in particular. The base resin used in the production of the prepreg of the present invention is usually an epoxy resin. As the epoxy resin, for example, 使用 (鼢) A-type epoxy resin, phenol novolak-type epoxy resin, and cresol novolak-type epoxy resin can be used. Resin, glycidyl amine (Ulyeidyl.
