Description
本発明は、樹脂トランスファー（ＲＴＭ）成形法による、軸受け部材を有するＦＲＰ成形品の一体成形法に関する。 The present invention relates to a method for integrally forming an FRP molded product having a bearing member by a resin transfer (RTM) molding method.
ＦＲＰは、不飽和ポリエステル樹脂、エポキシ樹脂、ポリイミド樹脂等の熱硬化性樹脂や、ポリエチレン、ポリプロピレン、ポリアミド、ＰＰＳ、ＰＥＥＫ等の熱可塑性樹脂のマトリックス樹脂と、炭素繊維、ガラス繊維、アラミド繊維等の繊維強化材とからなるものであり、軽量で且つ強度特性に優れるため、近年、航空宇宙産業から一般産業分野に至るまで、幅広い分野において利用されている。そして、その成形方法としては色々な方法・手段が知られているが、ＲＴＭ成形法は、特に多品種中量生産に適する成形法として注目されている。 FRP is a thermosetting resin such as unsaturated polyester resin, epoxy resin, polyimide resin, matrix resin of thermoplastic resin such as polyethylene, polypropylene, polyamide, PPS, PEEK, carbon fiber, glass fiber, aramid fiber, etc. In recent years, it is used in a wide range of fields from the aerospace industry to the general industrial field because it is made of a fiber reinforcing material and is lightweight and excellent in strength characteristics. Various methods and means are known as the molding method, and the RTM molding method is attracting attention as a molding method particularly suitable for high-mix medium-volume production.
ＲＴＭ成形法においては、上型と下型からなる金型内部に、繊維強化材を成形品形状に賦形したプリフォーム又はシート状の繊維強化材を配置し、金型を型締めした後、上型と下型が形成するキャビティ内を、金型の排出口から排出用ホースを介して排気し、一方、金型の注入口から注入用ホースを介して樹脂をキャビティ内に注入して繊維強化材に含浸せしめ、そして必要なら加熱して硬化させる方法がとられる。プリフォームとは、例えば、繊維強化材の連続ストランドを熱可塑性樹脂をバインダーとして結合し、成形型に近似した形状寸法に製作した半成形品である。 In the RTM molding method, a preform or sheet-shaped fiber reinforcement formed by molding a fiber reinforcement into a molded product shape is placed inside a mold composed of an upper mold and a lower mold, and the mold is clamped, The cavity formed by the upper mold and the lower mold is evacuated from the mold discharge port through the discharge hose, while the resin is injected into the cavity from the mold injection port through the injection hose. The reinforcing material is impregnated and, if necessary, heated and cured. The preform is, for example, a semi-molded product manufactured by combining continuous strands of fiber reinforcing material with a thermoplastic resin as a binder and having a shape approximate to a mold.
上記のようなＲＴＭ成形法は、従来幾つかの部品の組み立てによって製作していた製品を、一体的に成形することができるという特徴を有する。そして、また、他の部品あるいは副資材等を所望の箇所に配置あるいは設置した製品を、一体的に成形加工できるという利点もある。このような特徴・利点を利用して、金属部材等を有する各種のＦＲＰ成形品が製造されている（例えば、特許文献１〜３参照）。そして、本発明者はそれらの応用の一つとして、例えば、風力発電のブレードのように、回転中心軸を持ったＦＲＰ成形品の成形について検討している過程で、特定の金属部材に特定の前処理を施しておけば、非常に優れた一体成形品が得られることを見出した。
例えば、風力発電のブレードのように、回転中心軸を持ったＦＲＰ成形品をＲＴＭ成形法で成形する場合、回転部材の回転軸に対応して支持部材に耐摩耗性の金属ブッシュ等の軸受け部材を配置する必要がある。従来は、支持部材に、後加工により金属ブッシュ等を埋め込み接着するのが一般的な製法であった。しかし、かかる方法では、金属ブッシュ等の位置決めの困難さ、接着斑による性能のバラツキといった問題が発生し、その結果、工程の複雑化、更には、製作コストの増加という問題があった。本発明は、これを解決するために、金属ブッシュ等に特定の前処理を施したものを用いて、ＲＴＭ成形法により一体成形を行うものである。 For example, when an FRP molded product having a rotation center shaft such as a blade of wind power generation is molded by the RTM molding method, a bearing member such as a wear-resistant metal bush is supported on the support member corresponding to the rotation shaft of the rotation member. Need to be placed. Conventionally, it has been a common manufacturing method to embed and bond a metal bush or the like to a support member by post-processing. However, this method has problems such as difficulty in positioning the metal bush and the like, and variations in performance due to adhesion spots. As a result, there are problems in that the process is complicated and the manufacturing cost is increased. In order to solve this problem, the present invention performs integral molding by an RTM molding method using a metal bush or the like that has been subjected to a specific pretreatment.
本発明の請求項１に記載された発明は、繊維強化材とマトリックス樹脂とからなるＦＲＰ成形品であって回転軸を支える軸受け部材を有するものを、樹脂トランスファー（ＲＴＭ）成形法により一体成形するに際し、該軸受け部材として、その外表面の少なく一部に滑り止め加工が施され、且つ、少なくとも該滑り止め加工が施された部分が繊維強化材で被覆されたものを用いることを特徴とする軸受け部材を有するＦＲＰ成形品の一体成形法である。 In the invention described in claim 1 of the present invention, an FRP molded product comprising a fiber reinforcement and a matrix resin and having a bearing member for supporting a rotating shaft is integrally molded by a resin transfer (RTM) molding method. At this time, as the bearing member, a non-slip process is applied to at least a part of the outer surface, and at least a part subjected to the anti-slip process is coated with a fiber reinforcement. It is the integral molding method of the FRP molded product which has a bearing member.
請求項２に記載された発明は、軸受け部材が、金属ブッシュであることを特徴とする請求項１記載の軸受け部材を有するＦＲＰ成形品の一体成形法である。
The invention described in
そして、請求項３に記載された発明は、滑り止め加工が、ローレット加工によるものである請求項１又は２記載の軸受け部材を有するＦＲＰ成形品の一体成形法である。
The invention described in claim 3 is the method for integrally forming an FRP molded product having a bearing member according to
本発明の一体成形法によると、金属ブッシュの位置決めの簡便化及び確実化を実現できる上、ＦＲＰ成形品と金属ブッシュの接着性を向上させることができ、引いては優れた品質のＦＲＰ成形品を効率良く成形することができる。 According to the integral molding method of the present invention, the positioning of the metal bush can be simplified and ensured, and the adhesion between the FRP molded product and the metal bush can be improved. Can be formed efficiently.
本発明は、繊維強化材とマトリックス樹脂とからなるＦＲＰ成形品であって回転軸を支える軸受け部材を有するものを、ＲＴＭ成形法により一体成形するに際し、該軸受け部材として、その外表面の少なく一部に滑り止め加工が施され、且つ、少なくとも該滑り止め加工が施された部分が繊維強化材で被覆されたものを用いる方法である。 The present invention provides an FRP molded product composed of a fiber reinforcing material and a matrix resin and having a bearing member that supports a rotating shaft, when the integral molding is performed by the RTM molding method. This is a method in which a part is subjected to an anti-slip process and at least a part subjected to the anti-slip process is coated with a fiber reinforcing material.
回転軸を支える軸受け部材を有するＦＲＰ成形品とは、例えば、風力発電のブレードのように、回転体として構成されるＦＲＰ成形品において、回転部材の回転軸に対応し、その回転軸を支える軸受けを有するＦＲＰ成形品又は部材を意味する。軸受け部材としては、どのようなものでも良く、また、その材質は樹脂製のものでも良いが、耐摩耗性という点では、アルミ等の金属製のブッシュ（金属ブッシュ）が好ましい。 An FRP molded product having a bearing member that supports a rotating shaft is, for example, an FRP molded product configured as a rotating body, such as a wind power generation blade, corresponding to the rotating shaft of the rotating member and supporting the rotating shaft. Means an FRP molded article or member having Any member may be used as the bearing member, and the material thereof may be a resin, but a metal bush such as aluminum (metal bush) is preferable in terms of wear resistance.
本発明の一体成形法においては、前記軸受け部材として、その外表面の少なく一部に滑り止め加工が施されたものを用いる。滑り止め加工としては、どのような加工でも良いが、好ましいのはローレット加工によるものである。ローレット加工とは、主に丸物の滑り止めを目的として施された浅い切削加工を意味する。更に本発明の一体成形に際しては、前記軸受け部材の滑り止め加工が施された部分を、繊維強化材で被覆した状態で成形に供する。 In the integral molding method of the present invention, as the bearing member, one having a non-slip process applied to at least a part of its outer surface is used. As the non-slip process, any process may be used, but a knurling process is preferable. The knurling process means a shallow cutting process mainly for the purpose of preventing slippage of a round object. Further, in the integral molding of the present invention, the portion of the bearing member that has been subjected to the anti-slip process is subjected to molding in a state of being covered with a fiber reinforcing material.
以上のように、本発明においては、軸受け部材が最初から成形材料（プリフォーム等の繊維強化材）に挿入・配置されているので、従来の後加工による方法に比べ、接着工程及び位置決め等の工程を削減できる。また、軸受け部材の外表面の少なくとも一部に、ローレット加工等の滑り止め加工が施さており、且つ、少なくともこの滑り止め加工が施された部分が繊維強化材で被覆されて一体成形されるので、金属ブッシュ等の軸受け部材の接着強度の向上が実現される。 As described above, in the present invention, since the bearing member is inserted and arranged in the molding material (fiber reinforcing material such as preform) from the beginning, the bonding process, positioning, and the like are compared with the conventional post-processing method. Processes can be reduced. Further, since at least a part of the outer surface of the bearing member is subjected to anti-slip processing such as knurling, and at least a portion where the anti-slip processing is applied is covered with a fiber reinforcing material and integrally molded. Improvement of the adhesive strength of bearing members such as metal bushes is realized.

水平方向に対して回転中心軸（Φ１０ｍｍ）を持つ成形品を成形するよう考慮し、この中心軸部分に鉄製で、外径Φ２０ｍｍ×内径Φ１０ｍｍ、高さ２２．８５ｍｍの軸受け（金属ブッシュ）が配置されるような金型を製作した。金型に位置決め用のピンを配し、その位置決め用ピンに金属ブッシュを差し込めるように構成した。また、金型には、成形品表層にあたる繊維強化材と、厚み調整用のウレタン製フォーム材が配置できるだけのクリアランスを持たせた。金型には、樹脂注入口と排出口の役割を担う穴が最低２つあり、穴径Φ１０ｍｍ、穴の金型外側には３／８Ｂのテーパメスネジを深さ１５ｍｍで切っている。ここに一般で市販されているプッシュワン（メイルコネクタとも称される）（Φ１０ｍｍ×３／８Ｂ、オス・テーパネジ）を差し込んだ。
(1) Considering to mold a molded product having a rotation center axis (Φ10mm) with respect to the mold horizontal direction, this center shaft portion is made of iron and has an outer diameter of Φ20mm × inner diameter of Φ10mm and a height of 22.85mm ( A metal mold in which a metal bush) is arranged was manufactured. A positioning pin is arranged on the mold, and a metal bush can be inserted into the positioning pin. In addition, the mold was provided with a clearance sufficient for arranging a fiber reinforcing material corresponding to the surface layer of the molded product and a urethane foam material for adjusting the thickness. The mold has at least two holes serving as a resin injection port and a discharge port. A hole diameter Φ10 mm, and a 3 / 8B taper female screw is cut at a depth of 15 mm outside the hole mold. Here, a commercially available push one (also called a mail connector) (Φ10 mm × 3 / 8B, male taper screw) was inserted.
なお、このプッシュワンには細工を施した。即ち、ネジ側よりプッシュワン内部の真空用Ｏリングまで、Φ１０ｍｍのドリルを用いて既存の穴を広げておいた。これにより、金型内部まで樹脂製ホースを挿入することができる上、真空を保持しながら樹脂注入・排出が容易に可能となる。また、下型パーティングライン面上の外周には、金型内キャビティを真空状態に保ち、更に、注入される樹脂が外部に漏れるのを防ぐためのＯリングを配置した。Ｏリング配置用のミゾ形状は、高さ４．２ｍｍｈ×幅７．５ｍｍとした。また使用したＯリングは、外径Φ７ｍｍ×内径Φ３ｍｍのシリコン製中空ホースであった。 This push one was crafted. That is, the existing hole was expanded from the screw side to the vacuum O-ring inside Push One using a Φ10 mm drill. Thereby, the resin hose can be inserted into the mold, and the resin can be easily injected and discharged while maintaining the vacuum. Further, on the outer periphery on the lower parting line surface, an in-mold cavity was kept in a vacuum state, and an O-ring for preventing the injected resin from leaking outside was disposed. The groove shape for arranging the O-ring was 4.2 mmh high by 7.5 mm wide. The O-ring used was a silicon hollow hose having an outer diameter of Φ7 mm and an inner diameter of Φ3 mm.
（２）成型準備
先ず、金型に成形品の表層になるガラス基材を配置した。使用したガラス基材は日東紡社製
ガラス繊維織物ＷＬＡ１００Ｂ（２０８ｇ／ｍ２）を２層重ねて用いた。回転軸を支える軸受け部分はΦ８ｍｍでくり抜いた。そうすることで製品面にあたる全面に基材が配置できるようにした。次に、前記位置決め用のピンに小林鋲螺社製
高さ２２．８５ｍｍ、外径Φ２０ｍｍ×内径Φ１０ｍｍ、表面にローレット加工を施したアルミブッシュ（図１参照）を差し込んだ。軸受け部分以外の部分には、厚みを確保するためのウレタン製フォーム材を配置した。配置したウレタンフォームはサンコーウレタン社製（比重：０．０２ｇ／ｃｍ３）であった。
(2) Molding preparation First, a glass substrate serving as a surface layer of a molded product was placed in a mold. As the glass substrate used, two layers of glass fiber fabric WLA100B (208 g / m 2 ) manufactured by Nittobo Co., Ltd. were used. The bearing portion that supports the rotating shaft was cut out at Φ8 mm. By doing so, the base material can be arranged on the entire surface corresponding to the product surface. Next, an aluminum bush (see FIG. 1) having a height of 22.85 mm, an outer diameter of Φ20 mm, an inner diameter of Φ10 mm, and a knurled surface was inserted into the positioning pin. In parts other than the bearing part, a urethane foam material for securing the thickness was disposed. The arranged urethane foam was manufactured by Sanko Urethane Co., Ltd. (specific gravity: 0.02 g / cm 3 ).
一方、日東紡社製ガラス繊維織物ＷＲ５７０（５７０ｇ／ｍ２）を長さ５６ｍｍ×幅６０ｍｍで切り出し、アルミブッシュの中心軸に当たる部分をΦ２０ｍｍでくり抜いておいた。これを、すでに金型に配置されているアルミブッシュに４０層差し込んで、アルミブッシュのローレット加工面を覆うようにした。最後に反対側の表層基材として、ニットーボー社製ガラス繊維織物ＷＬＡ１００Ｂ（２０８ｇ／ｍ２）を２層、既に配置されているウレタン製フォーム材の上面に載せ、金型を閉じた。 On the other hand, a glass fiber fabric WR570 (570 g / m 2 ) manufactured by Nittobo Co., Ltd. was cut out with a length of 56 mm × width of 60 mm, and a portion corresponding to the central axis of the aluminum bush was cut out with Φ20 mm. Forty layers were inserted into an aluminum bush already arranged in the mold so as to cover the knurled surface of the aluminum bush. Finally, two layers of glass fiber woven fabric WLA100B (208 g / m 2 ) manufactured by Nittobo Co., Ltd. were placed on the upper surface of the urethane foam material already placed as the surface layer substrate on the opposite side, and the mold was closed.
（３）成形加工
樹脂注入口側のホースをクランプ等で閉じ、樹脂排出口側のホース端は真空ポンプにつないだ。真空ポンプを動作させ、金型内を真空状態にした。その後、樹脂注入ホースの先端を樹脂タンクの中に差し込み、クランプを開放した。真空圧力を利用し、樹脂タンクから金型内に樹脂が注入された。なお、樹脂としては、エポキシ樹脂であるアデカレジンＥＰ−４９０１（アデカ社製）を１００重量部と１，３−ＢＡＣ（三菱ガス化学社製）を２０重量部混合した混合液を用いた。金型内に樹脂が十分充填された後、樹脂注入口側及び排出口側のホースをクランプ等で閉じた。金型内は密閉状態となり、金型内部に注入された樹脂はその後硬化した。
(3) Molding processing The hose on the resin inlet side was closed with a clamp or the like, and the hose end on the resin outlet side was connected to a vacuum pump. The vacuum pump was operated and the mold was evacuated. Thereafter, the tip of the resin injection hose was inserted into the resin tank, and the clamp was released. Using vacuum pressure, the resin was injected from the resin tank into the mold. As the resin, a mixed liquid in which 100 parts by weight of Adeka Resin EP-4901 (manufactured by Adeka), which is an epoxy resin, and 20 parts by weight of 1,3-BAC (manufactured by Mitsubishi Gas Chemical Company) was mixed was used. After the mold was sufficiently filled with the resin, the hose on the resin inlet side and the outlet side was closed with a clamp or the like. The mold was hermetically sealed, and the resin injected into the mold was then cured.
（４）脱型
樹脂が十分硬化した後、金型を開放し脱型を行った。かかる方法で、アルミブッシュが一体成形されたＦＲＰ成形品が得られた。このように、本発明の方法によると、軸受け部材の位置決めが簡単であり、且つ、回転中心軸部分における成形品と軸受け部材の接着性が強力な成形品が得られる。
(4) After the demolding resin was sufficiently cured, the mold was opened and demolding was performed. By this method, an FRP molded product in which an aluminum bush was integrally formed was obtained. As described above, according to the method of the present invention, it is possible to obtain a molded product in which the positioning of the bearing member is simple and the adhesive property between the molded product and the bearing member at the rotation center shaft portion is strong.
