Description

DETAILED DESCRIPTION OF THE INVENTION The present invention generally relates to t
Regarding manufacturing equipment for reinforced composite materials, in particular, fiber reinforced composites for manufacturing fiber reinforced composite materials such as prepregs made by impregnating reinforcing fibers such as glass fibers and carbon fibers with resins such as epoxy resins as matrix resins. Related to material manufacturing equipment.

″　Bi.　r!i.

In recent years, various fiber-reinforced composite materials have been used in aerospace, land transportation,
It is widely used in various fields such as ships, construction and civil engineering, industrial parts, electroacoustic equipment, agricultural and fishing materials, and sporting goods. These fiber-reinforced composite materials are used as materials with excellent strength, heat resistance, corrosion resistance, friction, electrical properties, and light weight.
For example, it is manufactured as follows.

That is, as shown in FIG. 3, which schematically shows a fiber reinforced composite material manufacturing apparatus for manufacturing the above-mentioned fiber reinforced composite material, reinforcing fibers such as glass fibers and carbon fibers are wound and housed. The reinforcing fibers are supplied from the creel stand 12 to the roller group 14.
In step 4, the reinforcing fibers are aligned, the tension etc. are adjusted, and the fibers are opened.
Resin-coated paper made by coating a release paper with a viscous resin such as epoxy resin as a matrix resin is passed through resin-coated paper supply rollers 16 disposed on both sides of the reinforcing fibers to be supplied. 18, respectively, and the reinforcing fibers are impregnated with the resin on the resin-coated paper.

The reinforcing fibers impregnated with resin, that is, the reinforcing fibers impregnated with resin, then enter a pair of impregnated pressure rollers 20.22,
Pressure is applied via the upper and lower pattern III, and as a result, impregnation with the resin and reinforcing fibers is further performed, and the sheet is formed to a predetermined thickness, and is disposed downstream of the pair of impregnating pressure rollers 20 and 22. The prepreg is sent to a heating plate 24, where it is heated, and becomes a prepreg having a predetermined first-stage softness.

The thus prepared prepreg is further passed through a pair of impregnating pressure rollers 26 and 28, as described above, to further improve the impregnating properties of the resin and reinforcing fibers, and to obtain a predetermined thickness. After that, it is heated by heating plate 30 to form a prepreg having a predetermined softness in the second stage.

The prepreg produced in this way is further passed through a pair of impregnated pressure rollers 32, 34 to further improve the impregnating properties of the resin and the reinforced am, and is formed to a predetermined thickness, and then passed through a heating plate. 30a to form a prepreg having a predetermined softness in the third stage.

The produced prepreg is further passed through a pair of impregnating pressure rollers 32a and 34a to further improve the impregnating properties of the resin and reinforcing fibers, and is formed to a predetermined thickness. The prepreg that has been cooled and passed through the cooling plate 36 is transferred to the peeling roller 3
8, the upper release paper of the prepreg is peeled off, and the peeled upper release paper is transferred to the upper release paper winding reroller 40.
The lower release paper and the resin-impregnated reinforcing fibers, that is, the prepreg, which have been wound up and separated from the upper release paper by the peeling roller 38, are transferred to a pair of press rollers 44.
46, the prepreg is brought into close contact with the film supplied from the film supply roller 42 by these press rollers, and then the prepreg is sent to the prepreg take-up roller 4.
As a result, the resin-impregnated reinforcing fibers, that is, the prepreg, and the film unwound from the film supply roller 42 are tightly wound onto the lower release paper at the prepreg winding reroller 48, and the prepreg molded product is wound up. will be produced.

When producing prepreg in this way, conventionally, glass fibers are placed on resin such as epoxy resin on resin-coated paper.
In addition to supplying reinforcing fibers such as carbon fibers, predetermined processes such as heating and pressing are performed by arranging multiple pressure rollers and performing pressure and impregnation multiple times in 2nd and 3rd stages. Prepreg was produced by forming it to a hardness and thickness of .

However, in that case, since there is no pressing force between the pressure rollers at each stage that are arranged apart, the am group spread by the pressure roller tends to re-focus at the pressure roller outlet. In addition, the release paper, that is, the resin-coated paper, may float in the area where the pressure is no longer applied, and as a result, air bubbles may form in the resin on the resin-coated paper, which in turn may cause voids in the prepared prepreg. Alternatively, the appearance of the prepreg may deteriorate due to the appearance of striped patterns or the like. Furthermore, before the resin-coated paper enters the pressure rollers in the second and third stages, the resin on the resin-coated paper may form local resin pools (commonly called banks) on the resin-coated paper. Therefore, there is a problem in that the fibers supplied onto the resin-coated paper play.

As a result, the resin on the resin-coated paper and the supplied reinforcing fibers do not mix well, and therefore, it is not possible to obtain good adhesion between the resin and the reinforcing fibers, resulting in a prepreg with stable quality, high strength, and high density. The disadvantage is that it is difficult to manufacture.

λ Uni 1 Order The purpose of the present invention is to impregnate reinforcing fibers such as glass fibers, carbon fibers, and aramid fibers with matrix resin to make the resin and reinforcing fibers blend well when producing a fiber-reinforced composite material. By providing a fiber-reinforced composite material production device that can improve the impregnation effect and produce a stable quality, high-strength, high-density fiber-reinforced composite material that has good adhesion between resin and reinforcing fibers. be.

A resin-impregnated reinforced #1lta, that is, a prepreg, having a predetermined softness is produced. At this time, it is desirable that the supply inlet of the heat treatment device 124 to which the resin-coated paper is supplied be rounded, for example, by 10 to 50R, so as not to cut or damage the resin-coated paper.

When the fiber-reinforced composite material manufacturing apparatus 100 is put into operation, reinforcing fibers of, for example, seven colors are rolled from the creel stand 102 toward the roller group 104.

Width smaller than the width of each roller of 04, for example, width 20cm
The reinforcing fibers are aligned, the tension is adjusted, and the reinforcing fibers are pre-opened (see Figure 2).

Then, the resin-coated paper supply roller 106...
The resin-coated paper supplied from 108 is supplied from both sides to the resin-coated paper supply line L''2, and the reinforcing fibers are impregnated with the resin of the resin-coated paper.

At this time, the resin coated on the resin-coated paper is coated as a madrix resin, and is made of, for example, an epoxy resin liquid prepared as described below.

Epoxy The type of epoxy resin is bisphenol A-based 828 (oiled shell) 30 parts 1001 (oiled shell) 70 parts dicyandiamide 4 parts dichloromethyl urea 4 parts This reinforcing fiber is slightly impregnated with resin, i.e. resin impregnated reinforcement The fibers enter the gap between the bell 118 of the belt conveyor 120 and the heat treatment device 124, which are tensioned at the above-mentioned strength, and the resin-impregnated reinforcing fibers are coated with resin by the pressure roller 110 of the belt conveyor 120. Through the release paper on the top and bottom of the paper, for example at I K g/cm,
Pressure is applied to the heating plate 128 of the heat treatment device 124 to impregnate the reinforcing fibers with resin to a predetermined thickness, for example, 0.3 mm.
(See Figure 2C). At that time, the resin-impregnated reinforcing fiber is heated on a heating plate 1 whose temperature can be continuously changed.
28, the fibers are heated at, for example, 90° C. to form a first-stage resin-impregnated reinforcing fiber, ie, prepreg, having a predetermined softness.

Thereafter, the resin-impregnated reinforced Mil fibers of the first stage are pressed against the heat treatment device 124 by the tensioned belt 118 of the belt conveyor 120 in the gap between the belt 118 of the belt conveyor 120 and the heat treatment device 124. The resin-coated paper is conveyed over the heat treatment device 124 while being coated, and sent to the next impregnated pressure roller 112, which then passes through the release paper above and below the resin-coated paper again, for example, 5

, and is sent to the next cooling plate adhesion roller 114 disposed at a position corresponding to the cooling plate 130, and by this cooling plate adhesion roller 114, the resin-coated paper is passed through the upper and lower release papers. For example, the resin-impregnated reinforcing fibers, that is, the prepreg in the second stage are brought into close contact with the cooling plate 130 of the heat treatment device 124 at a weight of, for example, 1 kg and 70 m.
The resin is cooled by the cooling plate 130 to form a final resin-impregnated reinforcing fiber or prepreg having a predetermined softness and a predetermined thickness, for example, 0.15 mm (see FIG. 2e).

24, the upper release paper of the prepreg is peeled off by the peeling roller 132, and the peeled upper release paper is wound up by the upper release paper take-up reroller 134, and then by the peeling roller 132. , the lower release paper and the resin-impregnated reinforcing fibers, that is, prepreg, separated from the upper release paper, are moved by a pair of pressure rollers 138.14.
0 and is brought into close contact with the film supplied from the film supply roller 136 by these pressure rollers,
Thereafter, the prepreg is transferred to the prepreg take-up reroller 142
As a result, the resin-impregnated reinforcing fibers, that is, the prepreg, and the film unwound from the film supply roller 136 are tightly wound onto the lower release paper at the prepreg winding reroller 142, and a prepreg molded product is produced. be done.

In this way, prepreg manufacturing is carried out from opening the reinforcing fibers to impregnation, heating, and cooling.
In contrast to 4, since the process is carried out continuously while being pressed, the resin-impregnated reinforcing fibers can be wrapped around and attached to each impregnated pressure roller, compared to the conventional roller type in which multiple stages are provided and the process is carried out intermittently. This belt 118 prevents resin-impregnated reinforcing fibers from wrapping around and adhering to rollers during prepreg production, and as a result, prepregs made of thermoplastic resins such as nylon can also be produced, making it possible to reduce roughness. Thin prepregs with thin layers can also be produced.

In contrast to the above-mentioned conventional roller type in which temperature and pressure are applied intermittently to each roller section, the present invention uses the belt 118, so that the resin impregnation is moved over the heat treatment device 124. Temperature and pressure can be applied continuously and gently to the reinforcing fibers, and there is no need to release the temperature that should be applied, making it easy to adjust the temperature and pressure applied. be able to.

Furthermore, as mentioned above, prepreg manufacturing is performed continuously under pressure, from opening the reinforcing fibers to impregnation, heating, and cooling. , resin-impregnated reinforcing fibers are heat treated in equipment 1
24, and is conveyed over the heat treatment device 124, and is continuously pressurized and impregnated by the impregnating pressure rollers 110, 112 and the cooling plate adhesion roller 114, and furthermore, by the heating plate 128 of the heat treatment device 124. Since the prepreg is formed by continuously changing the temperature, the pressure is used to hold down the release paper of the resin-impregnated reinforcing fibers, that is, the resin-coated paper, while the prepreg is manufactured by being conveyed between the pressure rollers. , without causing that floating,
Therefore, it is possible to prevent the formation of air bubbles in the resin on the resin-coated paper, and it is also easier to control the temperature when producing the prepreg. As a result, it is possible to prevent the appearance of the prepared prepreg from deteriorating due to the formation of voids or striped patterns in the prepared prepreg. Furthermore, due to the above-mentioned suppression of the belt, the resin on the resin-coated paper forms a local resin pool (commonly known as a bank) before the resin-coated paper enters the pressure rollers in the second and third stages. )
As a result, the fibers supplied onto the resin-coated paper do not play.

As a result, it is possible to improve the impregnating property between the resin and the reinforcing m-fibers, as well as to obtain good adhesion, and to produce a prepreg with stable quality, high strength, and high density, that is, a fiber reinforced composite material. be able to.

In addition, in the above embodiment, the pressure roller and the heating plate and cooling plate of the heat treatment device were provided separately, but a pressure plate was provided at the position of the heat treatment device in the above embodiment, and a pressure plate corresponding to this pressure plate was provided. A pressure roller is provided at a position, and this pressure roller has the functions of a heating plate and a cooling plate, and the resin-impregnated reinforcing fibers supplied are pressurized by the pressure roller and heated and cooled at the same time. It may also be used as a configuration. In that case,
In the above embodiment, the pressure rollers 110 and 112 would be the pressure and heating rollers, and the cooling plate contact roller 114 would be the contact and cooling roller.

In this case, preferably, for example, the temperature of the pressure and heat roller 112 will be higher than the temperature of the pressure and heat roller 110.

Further, in the above embodiment, each pressure roller is configured as a pressure roller 110 and a pressure roller 112 so that its pressure force is individually different, but this is not limited to this embodiment. It goes without saying that the present invention can be practiced even if the applied pressure is configured to be the same, that is, uniformly applied.

In addition, in the above example, when producing prepreg,
We have described the case where resin coated paper was produced using the l1ill paper pattern, but as a modification of the above example, if Teflon coating is applied to the surface of the steel belt and the surface of the heat treatment equipment, the resin coated paper is produced using release paper. There is no need to make coated paper, and the reinforcing fibers supplied are directly impregnated with resin.
It becomes possible to produce prepreg.

As described above, according to the apparatus for manufacturing fiber reinforced composite materials of the present invention, the fiber-reinforced composite material manufacturing apparatus according to the present invention is capable of producing color images that are supplied by a belt conveyor configured by stretching a belt between a plurality of pressure rollers. The prepreg is produced by pressurizing and impregnating the spread portion of the reinforcing fibers with the matrix resin, so while the prepreg is produced by being conveyed between each pressure roller, the prepreg is pressed by the stretched belt conveyor. , the resin-impregnated reinforcing fiber release paper, that is, the resin-coated paper, is pressed down and does not cause it to float. Therefore, it is possible to prevent the formation of air bubbles in the resin on the resin-coated paper. As a result, it is possible to prevent deterioration of the appearance of the prepared prepreg due to the generation of voids or striped patterns in the prepared prepreg.

Furthermore, due to the above-mentioned suppression of the belt, the resin on the resin-coated paper does not form a resin pool on the resin-coated paper before the resin-coated paper enters the pressure rollers in the second and third stages. Therefore, it is possible to prevent the fibers supplied onto the resin-coated paper from sagging. As a result, it is possible to obtain good adhesion between the resin and the reinforcing fibers, and it is possible to stably produce a high-strength, high-density prepreg, that is, a fiber-reinforced composite material.
