Description

【0001】
【発明の属する技術分野】
本発明は、繊維強化樹脂複合体の製造方法に関し、更に詳しくは、コストの大幅な上昇を招くことなく積層工程を自動化できるようにした繊維強化樹脂複合体の製造方法に関する。
【0002】
【従来の技術】
炭素繊維などの強化繊維に熱硬化性樹脂組成物を含浸したプリプレグを加熱硬化してなる繊維強化樹脂複合体は、ゴルフクラブ、テニスラケット、スキー板などのスポーツ用途をはじめ、航空機やロケットなどの航空分野の構造材料として幅広く用いられている。
【0003】
従来、このような繊維強化樹脂複合体は、離型剤を塗布した積層治具上に作業者がプリプレグを順次積層してプリプレグ積層体を成形した後、該プリプレグ積層体を加熱硬化して製造するようにしている。
【0004】
近年では、例えば、強化繊維束に熱硬化性樹脂組成物を含浸した幅数ミリのトウプリプレグを用いて、積層工程を自動化することが行われるようになってきた。この積層工程は、予めボビンに巻き取られたトウプリプレグを引き出して圧着ローラにより積層治具上に圧着し、次いでカッターにより切断し、この工程を繰り返し行ってトウプリプレグを隙間なく敷き詰めることにより1層のプリプレグ成形体を形成し、このようなプリプレグ成形体を順次積層しながら形成することによりプリプレグ積層体を成形するものである。
【0005】
しかしながら、積層治具上には離型剤が塗布されているために治具の表面が滑り易く、その結果、1層目のプリプレグ成形体を形成する際に積層治具上にトウプリプレグが密着せずに剥がれ、それにより位置ズレが生じる。
【0006】
そこで、上記対策として、1層目のプリプレグ成形体を別途用意し、それを作業者が治具上の所定位置に位置決めして配置してから、2層目以降を上述したトウプリプレグにより自動形成せざるを得ない。そのため、積層工程を完全に自動化することができず、しかも1層目のプリプレグ成形体を別途用意しなければならず、更に人手を介するため、コストが大幅に上昇する。
【0007】
【発明が解決しようとする課題】
本発明の目的は、コストの大幅な上昇を招くことなく積層工程を自動化することが可能な繊維強化樹脂複合体の製造方法を提供することにある。
【0008】
【課題を解決するための手段】
上記目的を達成する本発明は、離型剤を塗布した積層治具上にマトリック樹脂として熱硬化性樹脂組成物を強化繊維に含浸したプリプレグを順次積層してプリプレグ積層体を成形し、該プリプレグ積層体を加熱硬化して繊維強化樹脂複合体を製造する繊維強化樹脂複合体の製造方法において、前記離型剤を塗布した積層治具上に前記熱硬化性樹脂組成物に含まれる成分を主成分とする粘着付与剤を塗布した後、前記プリプレグを積層することを特徴とする。
【0009】
このように離型剤を塗布した積層治具上に粘着付与剤を塗布し、その上にプリプレグを積層するようにしたので、プリプレグを積層治具上に密着して貼り付けることができ、位置ズレが生じることがない。そのため、従来のように1層目のプリプレグ成形体を別途用意したり、人手による作業が不要になり、積層工程を自動化してコストダウンを図ることができる。
【0010】
また、粘着付与剤がプリプレグのマトリックス樹脂に含まれる成分を主成分とするため、プリプレグのマトリックス樹脂製造時にその一部を利用でき、別途新たに初めから製造する必要がないので、コストの大幅な上昇を回避することができる。
【0011】
更に、加熱硬化後に積層治具を繊維強化樹脂複合体から除去した際に、1層目の表面には粘着付与剤の層が残るが、同じマトリックス樹脂に含まれる成分であるため、それを除去する必要がなく、繊維強化樹脂複合体成形後に新たな工程の増加を招くことがない。
【0012】
また、積層治具が複曲面形状の治具であっても容易にプリプレグを密着させて貼り付けることができるので、作業効率の改善が可能になる。
【0013】
【発明の実施の形態】
以下、本発明の構成について添付の図面を参照しながら詳細に説明する。
【0014】
図1は本発明の繊維強化樹脂複合体の製造方法の要部の一例を示し、1は積層治具、2は強化繊維束に熱硬化性樹脂組成物を含浸した幅数ミリのトウプリプレグPを積層治具1に圧着する圧着ローラ、3は不図示の複数のボビンからそれぞれ巻き出された複数のトウプリプレグPを配列して圧着ローラ2に送るガイド、4はトウプリプレグPをボビンから引き出す左右の駆動ローラ、5はトウプリプレグPを切断するカッター、6はトウプリプレグPが圧着される直前の圧着面を所定の温度に加熱するための温風を供給するノズルである。
【0015】
以下、本発明の方法を図1,2を参照しながら説明する。先ず、図2(a)に示すように、積層治具1の表面1aに離型剤を塗布して、離型剤層10を形成する。次いで、その離型剤層10上に、トウプリプレグPを貼り付ける前に、粘着付与剤を塗布手段7により塗布し、粘着付与層11を形成する。
【0016】
ここで使用される粘着付与剤は、トウプリプレグPを構成するマトリックス樹脂に含まれる成分を主成分とするものである。例えば、マトリックス樹脂に液状2官能型エポキシ樹脂を主成分とする120℃硬化型のエポキシ樹脂組成物を用いた場合、粘着付与剤は液状2官能型エポキシ樹脂を主成分とし、室温で適度な粘着性を有するように、例えば室温で固形のエポキシ樹脂のような添加剤を配合したエポキシ樹脂組成物である。
【0017】
このエポキシ樹脂組成物には、マトリックス樹脂と同種の硬化剤及び硬化促進剤を配合し、同じ硬化温度で硬化するようにするのが加熱工程を容易にする上で好ましい。
【0018】
例えば、上記120℃硬化型のエポキシ樹脂組成物が液状2官能型エポキシ樹脂100質量部に対し、室温で固形のエポキシ樹脂を1〜100質量部、高靱性化エポキシ樹脂を1〜50質量部、アミン系硬化剤を3〜30質量部含有する場合、粘着付与剤は液状2官能型エポキシ樹脂100質量部に対し、室温で固形のエポキシ樹脂を1〜100質量部、アミン系硬化剤を3〜30質量部含有するようにした配合にすることができる。
【0019】
図1に示す方法では、ノズル6からの温風によりトウプリプレグPが圧着される直前の圧着面が60℃程度に加熱されるため、この温度でも粘着性を有するようにしたものが使用される。このような粘着付与剤としては、上述したエポキシ樹脂の場合、難燃型エポキシ樹脂(室温で固形のエポキシ樹脂)及び/または高靭性化エポキシ樹脂を有するエポキシ樹脂組成物をBステージ化(予め樹脂及び硬化剤を部分的に反応させ、樹脂の分子量を上昇させること)したものが使用できる。好ましくは、粘着性を高めるため、Bステージ化したエポキシ樹脂組成物に更に液状2官能型エポキシ樹脂を微量(1〜10質量%)配合して調製したエポキシ樹脂組成物がよい。
【0020】
粘着付与剤は、上述したエポキシ樹脂組成物以外の熱硬化性樹脂組成物を用いた場合にも、上記と同様のことが言える。
【0021】
上記粘着付与剤は、有機溶剤により希釈してスプレー塗布されるが、その際の樹脂濃度としては10〜20質量%程度にするのがよい。粘着付与剤により形成される粘着付与層11の厚みとしては、0.01〜0.02mm程度になるようにするのがよい。
【0022】
粘着付与剤塗布後、圧着ローラ2を積層治具1の長手方向に移動させながらトウプリプレグPを積層治具1上の粘着付与層11上に圧着し、次いでカッター5により切断し、積層治具1を回転させて次の箇所に同様にしてトウプリプレグPを貼り付け、トウプリプレグPを隙間なく積層治具1上に敷き詰めて配列した1層目のプリプレグ成形体(プリプレグ)Xを形成する(図1及び図2(c)参照)。
【0023】
次いで、圧着ローラ2でトウプリプレグPを1層目のプリプレグ成形体上に同様にして圧着し、2層目のプリプレグ成形体Xを形成する。
【0024】
このプリプレグ積層工程では、圧着するトウプリプレグPを密着し易くして圧着面にエアを閉じ込めないようにするため、トウプリプレグPを圧着する直前の圧着面を圧着ローラ2と共に移動するノズル6からの温風により加熱する。
【0025】
所定の積層数のプリプレグ積層体Yが積層治具1上に成形される(図2(d)参照)と、それを従来と同様にして、加熱室で加熱硬化させて繊維強化樹脂複合体を得る。
【0026】
上述した本発明によれば、離型剤を塗布した積層治具1上に粘着付与剤を塗布し、その上にトウプリプレグPを積層して1層目のプリプレグ成形体Xを形成するようにしたので、トウプリプレグPが密着して剥がれることがない。そのため、位置ズレが生じることがないので、1層目のプリプレグ成形体を別途用意したり、人手による作業が不要となり、積層工程を自動化してコストダウンを図ることができる。
【0027】
しかも、粘着付与剤をプリプレグのマトリックス樹脂に含まれる成分を主成分とするため、プリプレグのマトリックス樹脂製造時にその一部を利用できるので、別途新たに初めから製造する必要がなく、従ってコストの大幅な上昇を招くことがなく、更に加熱硬化後に積層治具1を繊維強化樹脂複合体から除去した際に、1層目の表面には粘着付与層11が残るが、同じマトリックス樹脂であるため、それを除去する必要がなく、繊維強化樹脂複合体成形後に工程数を増加させることがない。
【0028】
また、図示する積層治具1のような複曲面形状の治具であっても容易にトウプリプレグPを密着させて貼り付けることができるので、作業効率を大幅に向上することができる。
【0029】
本発明において、トウプリプレグPのマトリックス樹脂に使用される熱硬化性樹脂組成物としては、従来公知のもの(エポキシ樹脂、マレイミド樹脂、ナジック酸末端基を有する樹脂、アセチレン末端基を有する樹脂、ビニル末端基を有する樹脂など)が使用でき、例えば、エポキシ樹脂を好ましく挙げることができる。
【0030】
トウプリプレグPの強化繊維としては、従来からプリプレグに用いられているものであればいずれの繊維であってもよく、例えば、強度の点からは炭素繊維を好ましく挙げることができる。
【0031】
本発明は、上記実施形態では、トウプリプレグPを使用する例を示したが、他の形状のプリプレグを用いて積層工程を自動で行うようにした場合にも、好適に用いることができる。
【0032】
【発明の効果】
上述したように本発明は、離型剤を塗布した積層治具上にプリプレグのマトリックス樹脂に含まれる成分を主成分とする粘着付与剤を塗布した後、プリプレグを積層するようにしたので、コストの大幅な上昇を招くことなく積層工程を自動化することが可能になる。
【0033】
また、繊維強化樹脂複合体成形後に新たな工程の増加を招くことがなく、更に積層治具が複曲面形状の治具であっても容易にプリプレグを密着させて貼り付けることができるので、作業効率の改善が可能になる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for producing a fiber-reinforced resin composite, and more particularly, to a method for producing a fiber-reinforced resin composite capable of automating a lamination process without causing a significant increase in cost.
[0002]
[Prior art]
Fiber reinforced resin composites made by heating and curing a prepreg in which a thermosetting resin composition is impregnated with reinforcing fibers such as carbon fibers are used for sports applications such as golf clubs, tennis rackets and skis, as well as aircraft and rockets. It is widely used as a structural material in the aviation field.
[0003]
Conventionally, such a fiber-reinforced resin composite is manufactured by laminating prepregs sequentially on a laminating jig coated with a release agent to form a prepreg laminate, and then heating and curing the prepreg laminate. I am trying to do it.
[0004]
In recent years, the laminating process has been automated using, for example, a tow prepreg having a width of several millimeters in which a thermosetting resin composition is impregnated into a reinforcing fiber bundle. In this laminating step, the tow prepreg previously wound on a bobbin is pulled out, pressed on a laminating jig by a pressure roller, then cut by a cutter, and this step is repeated to spread the tow prepreg without gaps to form one layer. The prepreg molded article is formed, and the prepreg molded article is formed by sequentially laminating such prepreg molded articles.
[0005]
However, the surface of the jig is liable to slip because the release agent is applied on the lamination jig. As a result, the tow prepreg adheres to the lamination jig when forming the first-layer prepreg molded body. Without being peeled off, thereby causing misalignment.
[0006]
Therefore, as a countermeasure, a prepreg molded body of the first layer is separately prepared, the worker positions and arranges it at a predetermined position on the jig, and then the second and subsequent layers are automatically formed by the above-described tow prepreg. I have to do it. For this reason, the lamination process cannot be completely automated, and the first-layer prepreg molded body must be separately prepared. Further, since a manual operation is required, the cost is significantly increased.
[0007]
[Problems to be solved by the invention]
An object of the present invention is to provide a method of manufacturing a fiber-reinforced resin composite that can automate a lamination step without causing a significant increase in cost.
[0008]
[Means for Solving the Problems]
The present invention to achieve the above object is to form a prepreg laminate by sequentially laminating a prepreg in which a thermosetting resin composition is impregnated into a reinforcing fiber as a matrix resin on a laminating jig coated with a release agent. In the method for producing a fiber-reinforced resin composite by heat-curing the laminate to produce a fiber-reinforced resin composite, the components contained in the thermosetting resin composition are mainly placed on a lamination jig coated with the release agent. After applying a tackifier as a component, the prepreg is laminated.
[0009]
As described above, the tackifier is applied on the laminating jig on which the release agent is applied, and the prepreg is laminated thereon, so that the prepreg can be stuck and adhered on the laminating jig. No deviation occurs. Therefore, it is not necessary to separately prepare a first-layer prepreg molded body as in the related art, and it is not necessary to perform a manual operation, and the cost can be reduced by automating the lamination process.
[0010]
In addition, since the tackifier is mainly composed of the components contained in the prepreg matrix resin, a part of the prepreg matrix resin can be used at the time of producing the prepreg matrix resin, and it is not necessary to newly produce the prepreg matrix resin from the beginning. Ascent can be avoided.
[0011]
Furthermore, when the laminating jig is removed from the fiber reinforced resin composite after heat curing, a tackifier layer remains on the surface of the first layer, but since it is a component contained in the same matrix resin, it is removed. It is not necessary to perform the process, and the number of new processes does not increase after molding the fiber-reinforced resin composite.
[0012]
Further, even if the laminating jig is a jig having a multi-curved surface, the prepreg can be easily adhered and adhered, so that the working efficiency can be improved.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the configuration of the present invention will be described in detail with reference to the accompanying drawings.
[0014]
FIG. 1 shows an example of a main part of a method for producing a fiber-reinforced resin composite of the present invention, wherein 1 is a laminating jig, 2 is a tow prepreg P having a width of several millimeters obtained by impregnating a reinforcing fiber bundle with a thermosetting resin composition. Roller, which presses the prepreg on the laminating jig 1, a guide for arranging a plurality of tow prepregs P respectively unwound from a plurality of bobbins (not shown) and feeding the prepreg P to the press roller 2, and a pull-out tow prepreg P from the bobbin. Left and right drive rollers, 5 are cutters for cutting the tow prepreg P, and 6 are nozzles for supplying hot air for heating the press-bonded surface immediately before the tow prepreg P is press-bonded to a predetermined temperature.
[0015]
Hereinafter, the method of the present invention will be described with reference to FIGS. First, as shown in FIG. 2A, a release agent is applied to the surface 1 a of the lamination jig 1 to form a release agent layer 10. Next, before attaching the tow prepreg P to the release agent layer 10, a tackifier is applied by the application unit 7 to form the tackifier layer 11.
[0016]
The tackifier used here is mainly composed of a component contained in the matrix resin constituting the tow prepreg P. For example, when a 120 ° C. curing type epoxy resin composition containing a liquid bifunctional epoxy resin as a main component is used as a matrix resin, the tackifier contains a liquid bifunctional epoxy resin as a main component and has a moderate tack at room temperature. An epoxy resin composition containing an additive such as an epoxy resin which is solid at room temperature so as to have properties.
[0017]
It is preferable to mix a curing agent and a curing accelerator of the same type as the matrix resin with the epoxy resin composition so that the epoxy resin composition is cured at the same curing temperature in order to facilitate the heating step.
[0018]
For example, the epoxy resin composition curable at 120 ° C. is 100 parts by mass of a liquid bifunctional epoxy resin, 1 to 100 parts by mass of a solid epoxy resin at room temperature, 1 to 50 parts by mass of a toughened epoxy resin, When the amine-based curing agent is contained in an amount of 3 to 30 parts by mass, the tackifier is 1 to 100 parts by mass of a solid epoxy resin at room temperature, and the amine-based curing agent is 3 to 100 parts by mass of the liquid bifunctional epoxy resin. It can be formulated so as to contain 30 parts by mass.
[0019]
In the method shown in FIG. 1, the pressurized surface immediately before the tow prepreg P is pressurized is heated to about 60 ° C. by the hot air from the nozzle 6, and therefore, a material that has adhesiveness even at this temperature is used. . As such a tackifier, in the case of the above-described epoxy resin, the epoxy resin composition having a flame-retardant epoxy resin (a solid epoxy resin at room temperature) and / or an epoxy resin having a high toughness is B-staged (pre-resin). And by partially reacting the curing agent to increase the molecular weight of the resin). Preferably, an epoxy resin composition prepared by further blending a small amount (1 to 10% by mass) of a liquid bifunctional epoxy resin with the B-staged epoxy resin composition to enhance the adhesiveness is preferred.
[0020]
The same applies to the case where a thermosetting resin composition other than the epoxy resin composition is used as the tackifier.
[0021]
The tackifier is diluted with an organic solvent and spray-applied. The resin concentration at this time is preferably about 10 to 20% by mass. The thickness of the tackifier layer 11 formed by the tackifier is preferably about 0.01 to 0.02 mm.
[0022]
After applying the tackifier, the tow prepreg P is pressed onto the tackifier layer 11 on the laminating jig 1 while moving the pressure roller 2 in the longitudinal direction of the laminating jig 1, and then cut by the cutter 5. 1 is rotated and the toe prepreg P is similarly adhered to the next position, and the first layer prepreg molded body (prepreg) X is formed by laying the tow prepreg P on the laminating jig 1 without gaps and arranging the toe prepregs P (FIG. 1 and 2 (c)).
[0023]
Next, the tow prepreg P is similarly pressed on the first-layer prepreg molded product by the pressure roller 2 to form a second-layer prepreg molded product X.
[0024]
In this prepreg laminating step, in order to make the tow prepreg P to be crimped easily adhered so that air is not trapped in the crimping surface, the crimping surface immediately before crimping the tow prepreg P together with the crimping roller 2 from the nozzle 6 is used. Heat with warm air.
[0025]
When a predetermined number of prepreg laminates Y are formed on the laminating jig 1 (see FIG. 2D), the prepreg laminate Y is heated and cured in a heating chamber in the same manner as in the related art to form a fiber reinforced resin composite. obtain.
[0026]
According to the present invention described above, a tackifier is applied on the laminating jig 1 on which the release agent is applied, and the tow prepreg P is laminated thereon to form the first-layer prepreg molded body X. As a result, the tow prepreg P does not come into close contact with and peel off. For this reason, there is no positional deviation, so that it is not necessary to separately prepare a first-layer prepreg molded body or to perform a manual operation, and it is possible to automate the lamination process and reduce costs.
[0027]
In addition, since the tackifier is mainly composed of the components contained in the matrix resin of the prepreg, a part of the matrix resin of the prepreg can be used at the time of production of the matrix resin. When the laminating jig 1 is further removed from the fiber-reinforced resin composite after heating and curing without causing any significant rise, the tackifier layer 11 remains on the surface of the first layer, but since it is the same matrix resin, There is no need to remove it, and there is no increase in the number of steps after molding the fiber-reinforced resin composite.
[0028]
Further, even with a jig having a multi-curved surface such as the lamination jig 1 shown in the figure, the tow prepreg P can be easily brought into close contact with the jig, so that the working efficiency can be greatly improved.
[0029]
In the present invention, as the thermosetting resin composition used for the matrix resin of tow prepreg P, conventionally known ones (epoxy resin, maleimide resin, resin having a nadic acid terminal group, resin having an acetylene terminal group, vinyl resin) For example, epoxy resins can be preferably used.
[0030]
As the reinforcing fiber of the tow prepreg P, any fiber may be used as long as it has been conventionally used for the prepreg. For example, carbon fiber is preferable from the viewpoint of strength.
[0031]
In the above embodiment, the example in which the tow prepreg P is used has been described. However, the present invention can also be suitably used in a case where the lamination process is automatically performed using a prepreg having another shape.
[0032]
【The invention's effect】
As described above, the present invention applies a tackifier containing a component contained in a matrix resin of a prepreg as a main component on a laminating jig to which a release agent is applied, and then laminates the prepreg. It is possible to automate the laminating process without causing a significant increase in the number of layers.
[0033]
In addition, since the number of new processes does not increase after molding the fiber reinforced resin composite, even if the laminating jig is a jig having a multi-curved surface shape, the prepreg can be easily adhered to and adhered to the laminating jig. Efficiency can be improved.
