　本発明の実施の形態の例について、以下、図に基づいて説明する。 Examples of embodiments of the present invention will be described below with reference to the drawings.
　＜第１実施形態＞
　図１は、本発明のＦＲＰ成形方法に係る割り型の本体１の上面図、図２は、本体１のＡ－Ａ′線における断面図である。図１に示すように、割り型の本体１は、通常は厚さ８～１０ｍｍ程度であり、通常のＦＲＰの型と同様の精度強度で良い。 <First Embodiment>
FIG. 1 is a top view of a split mold main body 1 according to the FRP molding method of the present invention, and FIG. 2 is a cross-sectional view of the main body 1 taken along the line AA ′. As shown in FIG. 1, the split mold body 1 is usually about 8 to 10 mm in thickness, and may have the same precision and strength as a normal FRP mold.
　まず、この本体１に離型剤を塗り適量のガラス繊維２を敷く。次に、図２に示すように、離型剤を塗った割り型のカバー３をかぶせる。割り型のカバー３の端部に空気通路４、空気吸引金属金具５を取り付けパイプで真空ポンプ６につなぐ。割り型のカバー３の中央部には、樹脂注入金属金具７を取り付けておく。 First, a release agent is applied to the main body 1 and an appropriate amount of glass fiber 2 is laid. Next, as shown in FIG. 2, a split-type cover 3 coated with a release agent is applied. An air passage 4 and an air suction metal fitting 5 are attached to the end of the split cover 3 and connected to the vacuum pump 6 by a pipe. A resin-injected metal fitting 7 is attached to the center of the split-type cover 3.
　すべてのセットが終わったら、割り型の本体１、割り型のカバー３の接合部をグルテン入りパテ８で密封する。 When all the sets are completed, the joint part of the split mold main body 1 and split mold cover 3 is sealed with a gluten putty 8.
　その後、空気吸引金属金具５より真空ポンプ６にて空気を吸引し、樹脂注入金属金具７より熱硬化樹脂を注入し硬化させる。 Thereafter, air is sucked from the air suction metal fitting 5 by the vacuum pump 6, and a thermosetting resin is injected from the resin injection metal fitting 7 to be cured.
　グルテン入りパテ８は、小麦粉に水を加え練りグルテンを発生させた後に、離型剤として且つ流動性をあげるために油を、増量剤として且つ流動性を下げるためにタルクを入れ使いよい粘土にして使用する。 Gluten pate 8 is a clay that can be used by adding water to wheat flour and generating gluten, and then adding oil as a mold release agent and increasing fluidity, and adding talc as an extender and lowering fluidity. To use.
　すなわち、密封用のパテ８は、水、小麦粉、タルク、油を適量で混ぜて調製することができる。小麦粉としては、グルテンを多く発生させるため、たんぱく質成分が多い（１０～１４質量％）市販の強力粉を用いることができる。油は、市販のサラダ油を使用することができる。 That is, the sealing putty 8 can be prepared by mixing water, flour, talc, and oil in appropriate amounts. As wheat flour, commercially available strong flour containing a large amount of protein components (10 to 14% by mass) can be used to generate a large amount of gluten. Commercially available salad oil can be used as the oil.
　パテ全体のうち、小麦粉は３０～４０質量％、タルクは、２５～３５質量％である。 ¡Wheat flour is 30-40% by mass and talc is 25-35% by mass.
　このように、両面テープをグルテン入りパテに変える事で、セットが容易となると共に、ゴミを減少させ量産することが可能である。また、このようなパテは、再利用可能で、かつ無害で廃棄しやすいという利点がある。 Thus, by changing the double-sided tape to putty with gluten, setting becomes easy, and it is possible to mass-produce with reduced dust. Also, such putty has the advantage of being reusable, harmless and easy to discard.
　＜第２実施形態＞
　次に、本発明の第２の実施形態について説明する。以下、上述の実施形態と同様の構成を有するものについては同様の符号を付し、詳細な説明は省略する。 Second Embodiment
Next, a second embodiment of the present invention will be described. Hereinafter, components having the same configurations as those of the above-described embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.
　図３は、本発明のＦＲＰ成形方法に係る割り型１１の分解斜視図、図４は、割り型１１のＢ－Ｂ′線における断面図である。図に示すように、本発明のＦＲＰ成形方法に係る割り型１１は、本体１１Ａと、上部カバー１１Ｂと、を備えている。 3 is an exploded perspective view of the split mold 11 according to the FRP molding method of the present invention, and FIG. 4 is a cross-sectional view of the split mold 11 taken along line BB ′. As shown in the figure, the split mold 11 according to the FRP molding method of the present invention includes a main body 11A and an upper cover 11B.
　本体１１Ａは、実際の成形型１３Ａの縁にフランジ状の密封代（シロ）１２Ａを備えている。この密封代１２Ａの外縁及び内縁には、パテ８が塗布されている。具体的に、密封代１２Ａを取り囲む外縁には、外側パテ部１２１が設けられている。また、その内側には、成形型１３Ａを取り囲むように、内側パテ部１２２が設けられている。また、本体１１Ａの成形型１３Ａの内部には、樹脂注入管１４に接続された樹脂注入口１４Ａが形成されている。 The main body 11A includes a flange-shaped sealing margin 12A on the edge of the actual mold 13A. The putty 8 is applied to the outer edge and the inner edge of the sealing allowance 12A. Specifically, an outer putty portion 121 is provided on the outer edge surrounding the sealing allowance 12A. Further, an inner putty portion 122 is provided on the inner side so as to surround the molding die 13A. Further, a resin injection port 14A connected to the resin injection tube 14 is formed inside the molding die 13A of the main body 11A.
　上部カバー１１Ｂも同様に、成形型１３Ｂの縁にフランジ状の密封代（シロ）１２Ｂを備えている。この密封代１２Ｂには、密封代１２Ａに形成される外側パテ部１２１と内側パテ部１２２との間に生じる空間を吸引可能な位置、すなわち外縁及び内縁の間の位置に、強真空吸引口１５が設けられている。また、上部カバー１１Ｂの成形型１３Ｂには、型内部を吸引可能な位置に弱真空吸引口１６が設けられている。両吸引口は、それぞれ強吸引又は弱吸引が可能な、図示しない真空ポンプに接続されている。 Similarly, the upper cover 11B is provided with a flange-shaped sealing margin 12B on the edge of the mold 13B. The sealing margin 12B includes a strong vacuum suction port 15 at a position where the space formed between the outer putty portion 121 and the inner putty portion 122 formed in the sealing margin 12A can be sucked, that is, a position between the outer edge and the inner edge. Is provided. Further, the molding die 13B of the upper cover 11B is provided with a weak vacuum suction port 16 at a position where the inside of the die can be sucked. Both suction ports are connected to a vacuum pump (not shown) capable of strong suction or weak suction.
　図４に、このような割り型の使用例を示す。まず、成形型１３Ａ及び１３Ｂ内部に、強度強化用の繊維を兼ねた隙間確保材１７を配置するのが好ましい。隙間確保材１７は、例えば、樹脂パテ付のガラス繊維シート（ガラスマット、ロービングクロス、ガラスクロス等）である。図５に、目の粗いガラス繊維のロービングクロスに、ポリエステルとタルクからなるパテ材を筋状の縞模様となるようにスクリーン印刷により塗布することで得られた隙間確保材１７を示す。このように、パテ材を縞模様に塗布することで、成形型内部で重ねた場合でも隙間が確保される。この隙間が注入された樹脂が通る通路の役目を果たし、途中で止まることなく、樹脂を全体に行き渡らせることが容易となる。 Fig. 4 shows an example of using such a split mold. First, it is preferable to arrange the gap ensuring material 17 that also serves as a strength reinforcing fiber inside the molds 13A and 13B. The gap ensuring member 17 is, for example, a glass fiber sheet (glass mat, roving cloth, glass cloth, etc.) with a resin putty. FIG. 5 shows a gap ensuring material 17 obtained by applying a putty material made of polyester and talc to a roving cloth made of glass fibers having a coarse mesh by screen printing so as to form a stripe pattern. In this way, by applying the putty material in a striped pattern, a gap is secured even when stacked inside the mold. This gap serves as a passage through which the injected resin passes, and it is easy to spread the resin throughout without stopping on the way.
　なお、成形型１３Ａ及び１３Ｂ内部には、さらに樹脂導入通路を設けておくのが望ましい。樹脂導入通路材１８は例えば、隙間のある管状の部材である。このような樹脂導入通路材１８は、図６（Ａ）に示すように、棒部材に、熱硬化性の樹脂を浸み込ませたガラス繊維を、隙間を作りながら巻きつけ、熱硬化させる。これにより、図６（Ｂ）に示すような、隙間を備えた樹脂導入通路材１８を作成することができる。なお、樹脂導入通路材１８は、その一端を樹脂注入口１４Ａ付近に配置し、他端を弱真空吸引口１６付近に配置するのが望ましい。 In addition, it is desirable to further provide a resin introduction passage inside the molds 13A and 13B. The resin introduction passage member 18 is, for example, a tubular member with a gap. As shown in FIG. 6 (A), such a resin introduction passage member 18 is wound around a rod member with glass fiber soaked in a thermosetting resin while forming a gap, and is thermally cured. Thereby, the resin introduction channel | path material 18 provided with the clearance gap as shown in FIG.6 (B) can be created. It is desirable that one end of the resin introduction passage member 18 be disposed near the resin injection port 14A and the other end be disposed near the weak vacuum suction port 16.
　このように準備された本体１１Ａに上部カバー１１Ｂをかぶせた後、まず、強真空吸引口１５から強真空吸引を開始する。なお、強真空吸引は、樹脂の注入が終了するまで絶えず行うものとする。これにより、外側パテ部１２１と内側パテ部１２２との間が吸引され、成形型空間の密封を確実なものとすることができる。 After the upper cover 11B is placed on the main body 11A thus prepared, first, strong vacuum suction is started from the strong vacuum suction port 15. Note that the strong vacuum suction is continuously performed until the injection of the resin is completed. Thereby, the space between the outer putty part 121 and the inner putty part 122 is sucked, and the mold space can be reliably sealed.
　次に、弱真空吸引口１６から弱真空吸引を開始する。これにより、成形型空間は減圧され、樹脂注入口１４Ａから徐々に樹脂が内部へと流れ込む。注入された樹脂は、樹脂導入通路材１８を、その隙間から漏れ出しながら進む。これにより、注入した樹脂を全体に行き渡らせることが容易となる。なお、注入された樹脂の行き渡り状況に応じて、弱真空吸引の吸引力を調整するのが望ましい。 Next, weak vacuum suction is started from the weak vacuum suction port 16. Thereby, the mold space is decompressed, and the resin gradually flows into the inside from the resin inlet 14A. The injected resin advances through the resin introduction passage member 18 while leaking from the gap. This makes it easy to spread the injected resin throughout. In addition, it is desirable to adjust the suction force of weak vacuum suction according to the spread situation of the injected resin.
　以上、本発明の実施形態の例について説明した。 The example of the embodiment of the present invention has been described above.
　このように本発明によれば、密封用パテに、小麦粉を用いたグルテン入りのパテを使用することで、安価かつ再利用可能で、無害な上に廃棄も容易なＦＲＰ成形が可能となる。 Thus, according to the present invention, by using a putty containing gluten using flour as the sealing putty, it is possible to perform FRP molding that is inexpensive and reusable, harmless and easy to dispose of.
　また、樹脂導入通路材１８および隙間確保材１７を用いることで、樹脂を行き渡らせることがより確実となり、型の大きさや形状の自由度が増す。 Further, by using the resin introduction passage member 18 and the gap securing member 17, it becomes more certain that the resin is spread, and the degree of freedom of the size and shape of the mold is increased.
　さらに、強真空吸引により密封代を、弱吸引部分により成形型内部を別々に吸引することで、より確実に、精緻な成形を行うことが可能となる。 Furthermore, it is possible to perform more precise and precise molding by sucking the sealing allowance by strong vacuum suction and sucking the inside of the mold separately by the weak suction part.
　なお、本発明に係るＦＲＰ成形方法は上記に限らず、さらに多くの代替物、修正および変形例が当業者にとって明らかである。また、上記各実施形態や変形例における各特徴をそれぞれ組み合わせて用いることもできる。 The FRP molding method according to the present invention is not limited to the above, and many alternatives, modifications, and variations will be apparent to those skilled in the art. Also, the features in the above embodiments and modifications can be used in combination.
　例えば、樹脂導入通路は、複数配置してもよい。かかる場合、例えば樹脂注入口１４Ａを、成形型１３Ａの中央付近に形成し、その樹脂注入口１４Ａを中心にして放射状に樹脂導入通路材１８を配置する。これにより、更に偏りなく樹脂を行きわたらせることが出来る。 For example, a plurality of resin introduction passages may be arranged. In such a case, for example, the resin injection port 14A is formed near the center of the mold 13A, and the resin introduction passage members 18 are arranged radially around the resin injection port 14A. As a result, the resin can be distributed evenly.
