Description

本発明は、大型の複合材製品、たとえば風車ブレードや航空機部品等の複合材製品に適用される複合材製品製造方法に関する。   The present invention relates to a composite product manufacturing method applied to a composite product such as a large composite product such as a windmill blade or an aircraft part.

従来、たとえば風車のブレードやナセルカバー、航空機部品、及び繊維強化プラスチック（Fiber Reinforced Plastics ：ＦＲＰ）船等のように、大型の複合材製品を製造する複合材製品製造方法としては、真空含浸工法（ＶａＲＴＭ）と呼ばれる製造方法が広く普及している。この真空含浸工法は、オートクレーブ（圧力釜）等の大掛かりな設備が不要であること、大型構造物の一体成形が容易であること、そして、有機溶剤の揮発が少なく作業環境もよい、という特徴を有している。   Conventionally, as a composite material manufacturing method for manufacturing a large composite product such as a windmill blade, a nacelle cover, an aircraft part, and a fiber reinforced plastic (FRP) ship, a vacuum impregnation method ( A manufacturing method called VaRTM) is widely used. This vacuum impregnation method is characterized by the fact that large-scale equipment such as an autoclave (pressure cooker) is not required, that large-sized structures are easily formed integrally, and that the working environment is good with little volatilization of organic solvents. Have.

従来の真空含浸工法において、成形型上に載置した強化繊維基材は真空バッグに封入される。この後、真空バッグの内部が真空吸引され、真空状態とした真空バッグの内部に液状樹脂が注入される。この液状樹脂は、強化繊維基材に含浸した状態で硬化させる。
このような真空含浸工法において、真空の成形空間を形成する真空バッグとしては、使い捨てのナイロン製真空バッグフィルムや、再利用可能なシリコンバッグ（たとえば特許文献１及び２参照）が使用されている。
特開２００３−０４２０５６号公報 特表平１０−５０４５０１号公報 In a conventional vacuum impregnation method, a reinforcing fiber base placed on a mold is enclosed in a vacuum bag. Thereafter, the inside of the vacuum bag is vacuumed and liquid resin is injected into the vacuum bag that has been evacuated. This liquid resin is cured in a state of being impregnated into the reinforcing fiber base material.
In such a vacuum impregnation method, a disposable nylon vacuum bag film or a reusable silicon bag (see, for example, Patent Documents 1 and 2) is used as a vacuum bag for forming a vacuum forming space.
Japanese Patent Laid-Open No. 2003-042056 Japanese National Patent Publication No. 10-504501

上述したように、大型の複合材製品製造方法として広く利用されている真空含浸工法においては、使い捨てのため経済性に難がある真空バッグフィルムの代わりに、再利用可能なシリコンバッグを使用する方法が実用化されている。
しかし、従来のシリコンバッグは、板厚が厚く白濁色であることから、下記のような問題が指摘されている。 As described above, in the vacuum impregnation method that is widely used as a method for producing a large composite product, a method of using a reusable silicon bag instead of a vacuum bag film that is difficult for economical use because it is disposable. Has been put to practical use.
However, since the conventional silicon bag has a thick plate and a cloudy color, the following problems have been pointed out.

１）シリコンバッグは厚板であるため重量が重い。このため、製品が大型化すればするほどシリコンバッグも大きくなって重くなり、ハンドリングが困難となる。
２）重いシリコンバッグをガラス繊維基板等の強化繊維基材上に広げる際には、繊維上を引きずることになる。このため、強化繊維基材の繊維を所定位置からずらす可能性があり、繊維にしわを生じる等の欠陥が発生しやすくなる。
３）白濁色のシリコンバッグは、樹脂の流れや含浸状況を目視で確認することが困難であるから、未含浸欠陥の発見が困難となり、品質低下の原因となる。なお、使い捨ての真空バッグフィルムは、透明であるためガラス繊維への樹脂の含浸状況を目視で確認でき、従って、未含浸欠陥が発生した場合には即座に補修作業を実施できる。 1) Since the silicon bag is a thick plate, it is heavy. For this reason, the larger the product is, the larger and heavier the silicon bag becomes, and the handling becomes difficult.
2) When a heavy silicon bag is spread on a reinforcing fiber base such as a glass fiber substrate, it is dragged on the fiber. For this reason, there is a possibility that the fiber of the reinforcing fiber base may be displaced from a predetermined position, and defects such as wrinkling of the fiber are likely to occur.
3) Since it is difficult to visually check the flow and impregnation state of the resin in the cloudy white silicon bag, it becomes difficult to find an unimpregnated defect, which causes a reduction in quality. In addition, since the disposable vacuum bag film is transparent, the impregnation state of the resin into the glass fiber can be visually confirmed. Therefore, when an unimpregnated defect occurs, repair work can be performed immediately.

このように、従来のシリコンバッグは、板厚が厚く白濁色であることから、製造時の作業性や製品の品質に問題を有している。
本発明は、上記の事情に鑑みてなされたものであり、その目的とするところは、シリコンバッグの経済性を維持しつつ、作業性及び品質を向上させることができる複合材製品製造方法を提供することにある。 Thus, since the conventional silicon bag has a thick plate and a cloudy color, it has a problem in workability at the time of manufacture and product quality.
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a composite product manufacturing method capable of improving workability and quality while maintaining economics of a silicon bag. There is to do.

本発明は、上記の課題を解決するため、下記の手段を採用した。
本発明に係る複合材製品製造方法は、成形型の上に載置した強化繊維基材をシート状素材に封入する密封工程と、前記成形型と前記シート状素材との間に形成された成形空間内から真空引きする真空吸引工程と、真空とした前記成形空間の内部に液状樹脂を注入して前記強化繊維基材に含浸させる注入・含浸工程と、前記強化繊維基材に含浸した液状樹脂を硬化させる樹脂硬化工程と、を備えている真空含浸工法を用いて複合材製品を製造する複合材製品製造方法において、前記シート状素材として薄肉化した透明なシリコンシートが用いられていることを特徴とするものである。 In order to solve the above problems, the present invention employs the following means.
The composite product manufacturing method according to the present invention includes a sealing step in which a reinforcing fiber base placed on a mold is enclosed in a sheet material, and a molding formed between the mold and the sheet material. A vacuum suction step for evacuating from the space, an injection / impregnation step for injecting a liquid resin into the vacuumed molding space and impregnating the reinforcing fiber substrate, and a liquid resin impregnating the reinforcing fiber substrate In a composite product manufacturing method for manufacturing a composite product using a vacuum impregnation method comprising curing a resin, a transparent thin silicon sheet is used as the sheet material. It is a feature.

このような複合材製品製造方法によれば、シート状素材として薄肉化した透明なシリコンシートが用いられているので、成形空間を形成するシート状素材は、薄肉化によりシート全体の重量が軽量化され、かつ、透明化により内部を流れる液状樹脂の状態が可視化される。   According to such a composite material manufacturing method, since a thin transparent silicon sheet is used as a sheet material, the weight of the entire sheet is reduced by thinning the sheet material forming the forming space. In addition, the state of the liquid resin flowing inside is visualized by the transparency.

上記の発明において、前記シリコンシートは、シート内部に配置した強化繊維により強度を得て薄肉化されていることが好ましく、これにより、薄いシリコンシートの強度を確実に増して薄肉化することができる。   In the above invention, the silicon sheet is preferably thinned by obtaining strength by reinforcing fibers disposed inside the sheet, whereby the thin silicon sheet can be surely increased in strength and thinned. .

上述した本発明によれば、成形空間を形成するシート状素材の薄肉化により、シート全体の軽量化によりハンドリングが容易になる。さらに、成形空間を形成するシート状素材の透明化により、内部を流れる液状樹脂の状態が可視化されるため、樹脂の流れや含浸状況を目視で確認することが容易になる。
この結果、本発明の複合材製品製造方法によれば、シリコンバッグが有する経済性を維持しつつ複合材製品製造時の作業性を向上させることができ、さらに、未含浸欠陥や繊維にしわを生じる等の欠陥防止により複合材製品の品質を向上させることができるという顕著な効果を奏する。 According to the present invention described above, handling is facilitated by reducing the weight of the entire sheet by reducing the thickness of the sheet-like material forming the forming space. Furthermore, since the state of the liquid resin flowing inside is visualized by making the sheet material forming the molding space transparent, it becomes easy to visually confirm the flow and impregnation of the resin.
As a result, according to the composite product manufacturing method of the present invention, it is possible to improve the workability at the time of manufacturing the composite product while maintaining the economic efficiency of the silicon bag, and further, wrinkles on the unimpregnated defects and fibers There is a remarkable effect that the quality of the composite product can be improved by preventing defects such as occurrence.

以下、本発明に係る複合材製品製造方法の一実施形態を図面に基づいて説明する。
図１は、複合材製品を製造する際に採用される真空含浸工法（ＶａＲＴＭ）を示す説明図であり、図中の符号１は成形型（ツール）、２は強化繊維基材、３は剥離シート（ピールプライ）、４は樹脂拡散用網状シート（パスメディア）、１０は薄肉化した透明なシリコンシート（シート状素材）である。
また、図１において、図中の符号５は液状樹脂を成形空間内の強化繊維基材２へ注入するための注入口、６は液状樹脂の流出を防止するシール、７は成形空間内から真空引きするための吸引口、８は真空引きによる空気の流入を防止するシール、９は成形空間２へ注入された液体樹脂である。 Hereinafter, an embodiment of a composite product manufacturing method according to the present invention will be described with reference to the drawings.
FIG. 1 is an explanatory view showing a vacuum impregnation method (VaRTM) adopted when manufacturing a composite material product, in which 1 is a molding die (tool), 2 is a reinforcing fiber substrate, and 3 is peeling A sheet (peel ply), 4 is a mesh sheet for resin diffusion (pass media), and 10 is a thin transparent silicon sheet (sheet-like material).
In FIG. 1, reference numeral 5 in the drawing is an inlet for injecting the liquid resin into the reinforcing fiber base 2 in the molding space, 6 is a seal for preventing the liquid resin from flowing out, and 7 is a vacuum from the molding space. A suction port for drawing, 8 is a seal for preventing inflow of air due to evacuation, and 9 is a liquid resin injected into the molding space 2.

このような真空含浸工法は、たとえば風車のブレードやナセルカバー、航空機部品、及びＦＲＰ船等のように、特に大型の複合材製品を製造する場合に採用される複合材製品製造方法である。
本発明の複合材製品製造方法は、成形型１の上に載置した強化繊維基材２をシリコンシート１０に封入する密封工程と、成形型１とシリコンシート１０との間に形成された成形空間内から真空引きする真空吸引工程と、真空とした成形空間の内部に液状樹脂９を注入して強化繊維基材２に含浸させる注入・含浸工程と、強化繊維基材２に含浸した液状樹脂９を硬化させる樹脂硬化工程と、を備えている。 Such a vacuum impregnation method is a composite product manufacturing method that is employed when manufacturing particularly large composite products such as windmill blades, nacelle covers, aircraft parts, and FRP ships.
The composite material product manufacturing method of the present invention includes a sealing step in which a reinforcing fiber substrate 2 placed on a mold 1 is enclosed in a silicon sheet 10 and a mold formed between the mold 1 and the silicon sheet 10. A vacuum suction process for evacuating the space, an injection / impregnation process for injecting the liquid resin 9 into the vacuum forming space and impregnating the reinforcing fiber base 2, and a liquid resin impregnating the reinforcing fiber base 2 And a resin curing step for curing 9.

密封工程では、成形型１の上に強化繊維基材２を裁置し、成形完了後の剥離を容易にする剥離シート３と、液状樹脂９の拡散を促進するための樹脂拡散用網状シート４とを、強化繊維基材２の上面及び側面に被せる。この後、強化繊維基材２、剥離シート３及び樹脂拡散用網状シート４の上にシリコンシート１０を被せ、一方の側端部にシール６を介在させて注入口５を取り付けるとともに、他方の側端部にシール８を介在させて吸引口７を取り付ける。この結果、成形型１とシリコンシート１０との間には、強化繊維基材２をシリコンシート１０に封入してシール６，８により密封された成形空間が形成される。   In the sealing step, the reinforcing fiber substrate 2 is placed on the mold 1 to facilitate the peeling after the molding is completed, and the resin diffusion network sheet 4 for promoting the diffusion of the liquid resin 9. Are covered on the upper surface and the side surface of the reinforcing fiber base 2. Thereafter, a silicon sheet 10 is placed on the reinforcing fiber base 2, the release sheet 3, and the resin diffusion netting sheet 4, and the injection port 5 is attached to one side end portion with the seal 6 interposed therebetween, and the other side. The suction port 7 is attached with a seal 8 interposed at the end. As a result, a molding space is formed between the mold 1 and the silicon sheet 10 in which the reinforcing fiber base 2 is sealed in the silicon sheet 10 and sealed with the seals 6 and 8.

ここでシリコンバッグとして使用するシリコンシート１０は、薄肉化した透明なシリコンシートが用いられている。このシリコンシート１０は、一般にシリコーンゴムと呼ばれるものである。ここで、シリコーンゴムについて好適な具体例を挙げると、たとえば信越化学（株）の商品名「ＫＥ５５５−Ｖ」及びその同等品がある。
本発明では、上述したシート状素材のシリコンシート１０として、図３に示す板厚ｔが０．４〜２．０ｍｍの薄い透明なシリコーンゴムを使用する。なお、従来使用されているシリコンバッグの板厚は２〜５ｍｍ程度であるから、シリコンシート１０はかなり薄くて軽いものとなる。 Here, the silicon sheet 10 used as the silicon bag is a thin transparent silicon sheet. The silicon sheet 10 is generally called silicone rubber. Here, when a suitable specific example is given about silicone rubber, there exists a brand name "KE555-V" of Shin-Etsu Chemical Co., Ltd. and its equivalent, for example.
In the present invention, a thin transparent silicone rubber having a thickness t of 0.4 to 2.0 mm shown in FIG. In addition, since the plate | board thickness of the silicon bag currently used is about 2-5 mm, the silicon sheet 10 becomes quite thin and light.

このように、シート状素材として薄肉化した透明なシリコンシート１０を使用すると、薄肉化によりシート全体の重量が軽量化されたシリコンシート１０により成形空間を形成し、かつ、透明化により内部を流れる液状樹脂９の状態は可視化される。すなわち、薄肉化した透明なシリコンシート１０が、成形空間を形成するためのシリコンバッグとして機能する。
また、薄いシリコンシート１０は、変形が容易であるため、シリコンバッグ内部の凹凸とのなじみもよく、従って、液体樹脂９の樹脂溜まりを低減して品質向上に貢献する。 In this way, when the thin transparent silicon sheet 10 is used as a sheet-like material, a molding space is formed by the silicon sheet 10 in which the weight of the entire sheet is reduced by the thinning, and the inside flows by the transparency. The state of the liquid resin 9 is visualized. That is, the thin transparent silicon sheet 10 functions as a silicon bag for forming a molding space.
Further, since the thin silicon sheet 10 is easily deformed, the thin silicon sheet 10 is well adapted to the irregularities inside the silicon bag. Therefore, the resin reservoir of the liquid resin 9 is reduced, contributing to quality improvement.

そして、シリコンシート１０の強度を増すため、たとえば図２及び図３に示すように、シリコンシート素材１１のシート内部に強化繊維１２が配置されている。ここで使用する強化繊維１２は、たとえば直径を０．１〜１．０ｍｍ程度としたガラス繊維のより線が好適である。また、シリコンシート素材１１の内部に配置する強化繊維１２のピッチＰは、上下方向及び左右方向において、各々１．０〜１０ｍｍ程度が好適である。
このように、シート内部に強化繊維１２を配置したシリコンシート１０は、強化繊維１２が有する引張強度から破断等に対する強度を得られるため、薄肉化が容易になる。換言すれば、強化繊維１２が薄いシリコンシート１０の破断強度を確実に増すので、強化繊維１２がない場合と比較して、より一層薄肉化することができる。 And in order to increase the intensity | strength of the silicon sheet 10, as shown in FIG.2 and FIG.3, the reinforcing fiber 12 is arrange | positioned inside the sheet | seat of the silicon sheet raw material 11, for example. The reinforcing fiber 12 used here is preferably a glass fiber stranded wire having a diameter of about 0.1 to 1.0 mm, for example. The pitch P of the reinforcing fibers 12 arranged inside the silicon sheet material 11 is preferably about 1.0 to 10 mm in the vertical direction and the horizontal direction.
As described above, the silicon sheet 10 in which the reinforcing fibers 12 are arranged inside the sheet can obtain strength against breakage or the like from the tensile strength of the reinforcing fibers 12, and thus can be easily thinned. In other words, since the reinforcing fiber 12 surely increases the breaking strength of the thin silicon sheet 10, it can be made thinner than in the case where the reinforcing fiber 12 is not provided.

上述した密封工程の後には、成形型１とシリコンシート１０との間に形成された成形空間内から真空引きする真空吸引工程が実施される。この真空吸引工程では、吸引口７から真空引きして成形空間内を真空とし、次の注入・含浸工程では、真空とした成形空間の内部に注入口６から液状樹脂９が注入される。この液状樹脂９は、強化繊維基材２の全体にわたって含浸され、次の樹脂硬化工程において、強化繊維基材２に含浸した液状樹脂９を硬化させる。
こうして製造された複合材製品は、含浸した液状樹脂９を硬化させた強化繊維基材２がシリコンシート１０の中から取り出され、さらに、剥離シート３及び樹脂拡散用網状シート４が剥離・除去される。なお、ここで使用したシリコンシート１０は、次の複合材製品を製造する際に再使用される。 After the above-described sealing process, a vacuum suction process is performed in which a vacuum is drawn from the molding space formed between the mold 1 and the silicon sheet 10. In this vacuum suction step, the molding space is evacuated by vacuuming from the suction port 7, and in the next injection / impregnation step, the liquid resin 9 is injected from the injection port 6 into the vacuumed molding space. The liquid resin 9 is impregnated over the entire reinforcing fiber base 2, and the liquid resin 9 impregnated in the reinforcing fiber base 2 is cured in the next resin curing step.
In the composite product thus manufactured, the reinforcing fiber substrate 2 obtained by curing the impregnated liquid resin 9 is taken out of the silicon sheet 10, and the release sheet 3 and the resin diffusion network sheet 4 are peeled and removed. The In addition, the silicon sheet 10 used here is reused when manufacturing the next composite material product.

従って、上述した複合材製品製造方法によれば、成形空間を形成するシリコンシート１０の薄肉化によりシート全体が板厚ｔに比例して軽量化され、製造作業時にシリコンバッグとなるシリコンシート１０のハンドリングが容易になる。
さらに、成形空間を形成するシリコンシート１０の透明化により、成形空間内部を流れる液状樹脂の状態が可視化されるため、樹脂の流れや含浸状況をシリコンシート１０の外側から目視で確認することが容易になり、欠陥捕集の作業性が向上する。すなわち、最終的に液状樹脂９が含浸した際の気泡の残存状況を確認できるため、気泡の排出作業を的確に実施して複合材製品の品質を向上させることができる。
また、透明なシリコンシート１０は、使い捨てされる従来の真空バッグフィルムと同様に、含浸状況のモニタリングが可能になるので、液状樹脂９の含浸速度測定時に正確なデータを取得できる。 Therefore, according to the composite material manufacturing method described above, the thickness of the silicon sheet 10 that forms the forming space is reduced in proportion to the thickness t, and the silicon sheet 10 that becomes a silicon bag during the manufacturing operation is reduced. Handling becomes easy.
Furthermore, since the state of the liquid resin flowing inside the molding space is visualized by making the silicon sheet 10 forming the molding space transparent, it is easy to visually check the resin flow and impregnation from the outside of the silicon sheet 10. This improves the workability of defect collection. That is, since the remaining state of the bubbles when the liquid resin 9 is finally impregnated can be confirmed, the bubble discharging operation can be accurately performed to improve the quality of the composite material product.
In addition, since the transparent silicon sheet 10 can monitor the impregnation state in the same manner as a conventional vacuum bag film that is disposable, accurate data can be obtained when the impregnation rate of the liquid resin 9 is measured.

この結果、シリコンシート１０を用いたシリコンバッグが有する経済性、すなわち再利用が可能であるという経済性を維持しつつ、複合材製品製造時の作業性を向上させることができ、さらに、未含浸欠陥や繊維にしわを生じる等の欠陥防止により複合材製品の品質を向上させることができる。   As a result, while maintaining the economic efficiency of the silicon bag using the silicon sheet 10, that is, the economic efficiency of being reusable, it is possible to improve the workability at the time of manufacturing the composite material product. The quality of the composite product can be improved by preventing defects such as defects and wrinkles in the fibers.

ところで、上述した強化繊維１２の挿入量については、ピッチＰを狭めて多く（密に）すればシリコンシート素材１１の板厚ｔをさらに薄くすることが可能になる。しかし、強化繊維１２の挿入量を多くすると、透明なシリコンシート素材１１の可視化を妨げることになるので、板厚ｔと強化繊維１２の挿入量及び挿入形態は、成形する製品の大きさや要求される可視化の程度により適宜選択されるべきである。ここで、強化繊維１２の挿入形態とは、使用する強化繊維１２の種類、線経、強化繊維間のピッチＰ、強化繊維１２の配置方向（縦、横、斜め等）、板厚ｔ方向に配置する繊維数等について、選択される一または複数の組み合わせである。   By the way, about the insertion amount of the reinforced fiber 12 mentioned above, if the pitch P is narrowed and increased (densely), the thickness t of the silicon sheet material 11 can be further reduced. However, if the insertion amount of the reinforcing fiber 12 is increased, the transparent silicon sheet material 11 is prevented from being visualized. Therefore, the thickness t and the insertion amount and the insertion form of the reinforcing fiber 12 are required for the size of the product to be molded and required. It should be selected as appropriate according to the degree of visualization. Here, the insertion form of the reinforcing fibers 12 is the type of reinforcing fibers 12 to be used, the line diameter, the pitch P between the reinforcing fibers, the arrangement direction of the reinforcing fibers 12 (vertical, horizontal, diagonal, etc.), and the thickness t direction The number of fibers to be arranged is one or a plurality of combinations selected.

すなわち、シリコンシート１０に使用される強化繊維１２については、上述したガラス繊維に限定されることはなく、諸条件（たとえば、複合材製品の大きさや狙いとするシリコンシート素材１１の板厚ｔ等）に応じて引張強度の高い繊維材を適宜選択することができる。
本発明は、上述した実施形態に限定されることはなく、その要旨を逸脱しない範囲内において適宜変更することができる。 That is, the reinforcing fiber 12 used in the silicon sheet 10 is not limited to the glass fiber described above, but various conditions (for example, the size of the composite material product, the thickness t of the silicon sheet material 11 to be aimed at, etc.) ), A fiber material having a high tensile strength can be appropriately selected.
The present invention is not limited to the above-described embodiment, and can be modified as appropriate without departing from the scope of the invention.
