Definitions
- the present invention relates to a reinforced fiber sheet, a method for producing the same, and a dress-up sheet using the sheet.
- vertical and horizontal belts which are aggregates of many carbon fibers, are woven vertically and horizontally to reduce the weight and increase the strength of the vehicle body.
- the carbon cloth is embedded in the matrix resin.
- the carbon fiber constituting the carbon cloth is an ultrafine fiber, when immersed in a matrix resin in a mold, the carbon cloth is locally unraveled, and the vertical or horizontal band body may meander or twist. This may cause the appearance of the shaped vehicle parts to deteriorate.
- an acrylic carbon plate formed by firmly solidifying the above-mentioned carbon cloth with an acrylic resin is commercially available. Although this carbon plate is almost completely solidified at room temperature, it is 130 ° C to 200 ° C. Deforms freely when heated every time. For this reason, the carbon plate is deformed by heating and stored in a mold, and then, after the carbon plate is re-hardened, the mold is filled with a matrix resin, whereby the vertical band and Vehicle parts reinforced with carbon fiber can be formed neatly without meandering the horizontal band.
- the present invention has been made in view of the above circumstances and aims to improve the quality of a molded product without increasing production cost and production time by enabling a molded product in which a reinforcing fiber cloth is embedded to be manufactured cleanly and easily.
- vehicle parts using this type of carbon cloth are often mounted on vehicles with racing specifications such as F1, so reinforced fibers composed of vertical and horizontal bands are woven vertically and horizontally.
- the texture itself is of great value, especially among young car lovers.
- a dress application sheet in which such a texture pattern is artificially printed on the front surface and an adhesive layer is provided on the back surface is commercially available, and such a sheet is attached to the interior or exterior portion of a vehicle. , Dress up may be required.
- a dress-up sheet in which the texture pattern is only printed in a pseudo manner has the disadvantage that the surface is flat and there is no unevenness unique to real carbon cloth, and the appearance is rough and the appearance is rough. is there. Since the acrylic carbon plate does not deform unless heated to a high temperature, it is extremely difficult to use it as a dress-up sheet to be attached to an interior or exterior part of a vehicle.
- the present invention makes it possible to obtain a dress-up sheet having a real reinforcing fiber cloth and deforming relatively freely without heating, so that dress-up with a real textured pattern can be performed easily and inexpensively.
- Realization is the second purpose.
- the present invention has taken the following technical measures.
- the reinforcing fiber sheet according to the present invention includes a cross layer formed by weaving a vertical band and a horizontal band, which are an aggregate of a large number of reinforcing fibers, in a vertical and horizontal direction, and the vertical band and the horizontal band are connected to each other. And a cross reinforcing material impregnated in the cloth layer so that the cloth layer can be deformed at room temperature while being joined to each other.
- the cloth core material is immersed in the matrix resin.
- the vertical and horizontal bands do not meander or twist, and molded products such as vehicle parts can be formed neatly.
- the cloth layer can be deformed at room temperature while maintaining the joined state of the vertical band member and the horizontal band member. There is no need to heat the core material, and molding of molded products such as vehicle parts is very simple.
- the reinforcing fiber sheet according to the present invention can be used as a reinforcing material for a molded product by embedding it in a matrix resin when composed of only the above-mentioned cross core material, but is transparent and highly ductile.
- a synthetic resin multi-ductile sheet material By attaching a synthetic resin multi-ductile sheet material to the connecting reinforcing layer of the cloth core, it can be used as a raw material sheet for a dress-up sheet.
- a transparent and highly ductile synthetic material is used as a reinforcing layer for a cross core material that allows the cross layer to be deformed at room temperature while the vertical and horizontal bands are joined to each other. Since the resin-made ductile sheet material is stuck, the material sheet can be deformed relatively freely without heating, despite having a real reinforcing fiber mouth.
- an adhesive layer is provided on the back surface of a reinforcing fiber sheet (raw material sheet for dress-up sheet), which is formed by attaching a multi-ductile sheet material to the surface of the cloth core material, and a release sheet is provided on the back surface of the adhesive layer.
- a sticker-type dress-up sheet By sticking it, it is possible to obtain a sticker-type dress-up sheet to be later attached to, for example, an interior or exterior part of a vehicle.
- a cushion layer is provided on the back surface of the reinforcing fiber sheet, it is possible to obtain a skin-type dress upsheet used as, for example, a skin of a vehicle seat.
- the multi-ductile sheet material is not particularly limited as long as it is a material having ductility that does not hinder the deformation of the cloth core material.
- a synthetic resin base sheet and an ink showing abundant flexibility after drying are used.
- the joining reinforcing layer of the multi-ductile sheet material is formed on the back surface of the base sheet, the back surface of the joining reinforcing layer of the multi-ductile sheet material is covered with the cloth core material, and the base sheet is impregnated.
- the solvent component of the reinforcing layer is sealed as it is in the state at the time of manufacture, and volatilization to the outside is prevented.
- the dress sheet to which the ductile sheet material has been attached is shipped, the flexibility of the ink applied to the base sheet is maintained for a long time in the state at the time of manufacturing, and the life of the dress-up sheet is reduced. Can be increased.
- a reinforcing fiber sheet composed of only the cloth core material, which has a connecting reinforcing layer that allows the cloth layer to be deformable at room temperature while maintaining the bonded state of the vertical band and the horizontal band is, for example, a commercially available reinforcing fiber. It can be manufactured by screen printing the cloth (cloth layer).
- the method for producing a reinforcing fiber sheet (cloth core material) according to the present invention includes the following steps (a) to (c).
- a screen with a coarser number of meshes than the standard number of meshes is set on the upper surface of the cloth layer formed by weaving the vertical and horizontal bands, which are aggregates of a large number of reinforcing fibers, vertically and horizontally.
- the ink after drying serves as an adhesive medium so that the vertical band and the horizontal band are bonded to each other, and the flexibility of the ink allows the cloth layer to sufficiently deform even at room temperature so as to exhibit a deformability. become.
- the screen used for screen printing is 13 or less of the standard mesh number (the number of screen meshes determined by the ink maker as to obtain the best printing result for each ink) and It is preferable to set the number of meshes with a roughness of 1 Z 4 or more.
- the number of meshes of the screen exceeds 1/3 of the standard number of meshes, the amount of ink impregnated in the cloth layer will be insufficient, and the bonding strength between the vertical band and the horizontal band will be weakened and the cloth layer will be formed. If the number of meshes is less than the standard mesh number of 1 Z 4, the amount of ink impregnated in the cloth layer will be too large, and the bundle of reinforcing fibers will swell and the vertical and horizontal bands will be removed. This is because there is a risk that the thicknesses of the pieces may become uneven. Although the cycle of applying and drying the ink to the cloth layer is relatively good even if it is performed only once, this is repeated two or more times (especially two times is preferable). By doing so, the ink can be completely impregnated into the entire reinforcing fibers constituting the cloth layer.

- FIG. 1 shows a method for producing a cloth core material 4 mainly comprising the reinforcing fiber sheet 1.
- FIG. 1 (a) a printing plate 19 having a screen 18 on the upper surface of the cloth layer 13 is set, and FIG. 1 (b) As shown in (1), the ink 20 showing abundant flexibility after drying is supplied onto the screens 1 and 8 to perform screen printing, whereby the ink 20 is impregnated in the cross layer 13.
- the printing plate 19 used in the screen printing has a screen 18 having a mesh coarser than the standard use standard of the ink 20.
- the standard used is about 180 to 2525 mesh, and in the case of "Sericol EG screen ink", It is considered that the standard use standard of about 230 mesh is appropriate, but in the present embodiment, the screen 18 of the printing plate 19 is set to about 70 mesh of 1 Z3 or less of these standard use standards. It has been set.
- the screen 18 having such an extremely coarse opening a considerably large amount of the ink 20 is supplied onto the cloth layer 13, and as a result, a sufficient amount of the ink 20 is ensured.
- Each fiber of the cloth layer 13 is impregnated.
- the cloth layer 13 sufficiently impregnated with the ink 20 as described above has a horizontal band 11 and a horizontal band 11 due to the adhesion performance of the ink 20 after drying.

- the ink 20 in this case has abundant flexibility after drying, as shown in FIG. 2 (b), when the cloth core material 4 is pulled obliquely at room temperature, the vertical band 1 Although 1 and the horizontal strips 12 are inclined with respect to each other and deformed into a rhombus shape, their bonded state is maintained, and the cross layer 13 is not released.
- the screen 18 used for the screen printing is preferably set to a mesh number having a roughness of 1 Z 3 or less and 1/4 or more of the standard mesh number determined by the ink maker. The reason is that if the number of meshes of the screen 18 exceeds the standard mesh number of 1 Z3, the amount of ink impregnated in the cloth layer 13 will be insufficient, and the joining strength of the vertical band 11 and the horizontal band 12 This is because the cloth layer 13 becomes weaker and the cloth layer 13 becomes easier to unwind.
- the number of meshes on the screen 18 is less than the standard number of meshes of 1 Z4, the amount of ink impregnated in the cloth layer 13 will be too large, and the bundle of reinforcing fibers will swell and grow vertically. This is because the thickness of the band 11 and the width of the horizontal band 12 may be uneven.

- FIG. 7 (b) shows an external view of an example of the heating device 26, which has a built-in hot-air circulation type thermostat (not shown).
- the heating temperature is preferably 30 or more and 80 ° C. or less. The reason is that when the temperature is lower than 30 ° C., the ink 20 may not dry, and when the temperature exceeds 80 ° C., the solvent component may be rapidly removed to cause a waving phenomenon.
- the cloth layer 13 impregnated with the ink 20 is set on the screen printing machine 22 again, and under the same conditions as above, further having abundant flexibility after drying.
- the same ink 20 is applied, and subsequently, the same ink 20 is dried by the heating device 26 under the same conditions as above.
- the impregnation of the cloth 20 with the ink 20 becomes more reliable, and after the ink 20 is dried,
- the flexibility of the cross core material 4 can be improved.
- the application and drying cycle of the ink 20 to the cloth layer 13 is repeated twice, if the cycle is performed once for each side, the application of the ink 20 is repeated from either side of the front and back. Compared with the case, the impregnation of the cloth 20 with the ink 20 is further ensured, which is more preferable.
- FIG. 3 shows a method for producing a ductile sheet material 6 which is a constituent member of the reinforcing fiber sheet 1.
- a printing plate 29 having a screen 28 is set on the upper surface of a base sheet 15, and FIG.

- the printing plate 29 used in the screen printing also has a screen 28 having a mesh coarser than the standard use standard of the ink 30.
- the standard it is considered that about 180 to 225 mesh is suitable for use, and in the case of "Sericol EG screen ink", about 230 mesh is appropriate for the standard use.
- the screen 28 of the printing plate 29 is set to 120 mesh which is close to 12 of these standard usage standards.
- heating is preferably performed using the heating device 26 as shown in FIG. 3 (c).
- the heating temperature in this case is preferably 30 ° C. or higher and 80 or lower. The reason is that if it is less than 30, the flexibility of the ink 30 cannot be brought out very well, and if it exceeds 80, the sheet material 1 obtained after manufacturing may have waving. Because there is.
- the drying time tends to be longer when the temperature is lower than 50 ° C, and when the temperature exceeds 70, the sheet material 1 is rare. May cause minor damage. Therefore, it is suitable for practical use to set the value between 50 and 70 and below.
- the best conditions were preferably 60 ° C., and the heating time was preferably 15 minutes.
- the heat resistance is 70 ° C, and in some cases, 8 Ot is cleared. It is not particularly difficult to prevent the base sheet 15 and the ink 30 from being damaged by the heating itself.
- the base sheet 15 impregnated with the ink 30 is set again on the screen printing machine 22 under the same conditions as described above.
- the same ink 30 having flexibility is applied, and subsequently, the heating device 26 is used to dry the ink 30 under the same conditions as above.
- the cycle of applying and drying the ink 30 to the base sheet 15 is not so good as to be repeated many times, and after more than two times, even if the number of repetitions is increased, the effect is not remarkably improved.
- the most efficient number of repetitions of the application and drying cycle of the ink 11 is two.
- the multi-ductile sheet material 6 manufactured as described above is integrated with the surface of the cross core material 4 via a permanent adhesive layer 5 as shown in FIG.
- the fiber sheet 1 is used as a raw material sheet for the dress-up sheets 2 and 3 shown in FIGS. 5 and 6, for example.
- the cloth core 4 can be used as a reinforcing material for a molded product by embedding it in a matrix resin. In this case, there is no need to attach the multi-ductile sheet material 6, and the cloth core 4
- the reinforcing fiber sheet 1 is constituted only by this.
- the present invention is not limited to the above embodiment.
- the reinforcing fibers constituting the cloth layer 13 may be other than carbon fibers such as glass fibers and Kepler fibers.
- the cross layer 13 may employ not only a plain weave of the vertical band 11 and a horizontal band 12 but also a twill weave of them.
- the sticker 2 shown in FIG. 5 can be used by sticking not only to the exterior or interior parts of a vehicle, but also to all kinds of articles such as electronic devices such as notebook personal computers and household items such as ornaments.
- a molded product in which a reinforcing fiber cloth is embedded can be produced neatly and easily, so that the quality of the molded product can be improved without increasing the production cost and the production time. be able to.
- a dress-up sheet having a real reinforcing fiber cloth and being freely deformed without heating can be obtained, so that dress-up with a real weave pattern can be realized easily and inexpensively.
- the reinforcing fiber sheet according to the present invention is embedded in a matrix resin. It can be used as a reinforcing material for molded products. It can also be used as a sticker to be attached to the interior or exterior part of a vehicle or as an outer skin of a vehicle seat.
