Description
上記課題を解決するために、本発明に係る中空繊維強化プラスチックの製造方法は、固体粒子を水溶性粘着剤により結合することによりブロック体を形成し、該ブロック体を樹脂不浸透性の膜としての熱収縮フィルムを用いたプラスチックフィルムで覆うことにより中子を作製し、該中子を用いて該中子の周囲に繊維強化プラスチックを成形し、成形後に、前記水溶性粘着剤による結合を解除して前記中子内の固体粒子を成形された繊維強化プラスチックの外部へ排出することを特徴とする方法からなる。 In order to solve the above problems, a manufacturing method of a hollow fiber reinforced plastic according to the present invention, the solid particles block body is formed by binding the water-soluble adhesive, the block body as the resin impermeable film A core is made by covering with a plastic film using a heat-shrinkable film, and a fiber-reinforced plastic is molded around the core using the core. After the molding, the binding by the water-soluble adhesive is released. And discharging the solid particles in the core to the outside of the molded fiber reinforced plastic.
上記本発明に係る中空繊維強化プラスチックの製造方法においては、上記樹脂不浸透性の膜としては、とくにプラスチックフィルムを用いる。適切なプラスチックフィルムを用いることにより、確実に樹脂不浸透性能を満たすことができ、しかもそれを薄いフィルムで達成できる。また、プラスチックフィルムでは欠陥の有無の検査が容易であることからも、確実に樹脂不浸透性能を満たすことができる。さらに、薄いプラスチックフィルムを用いることにより、ブロック体の外形に沿わせて容易にかつ精度よく配置することができる。 In the method of manufacturing a hollow fiber-reinforced plastic according to the present invention, as the resin impermeable film, particularly Ru using a plastic film. By using an appropriate plastic film, the resin impermeability can be surely satisfied, and this can be achieved with a thin film. In addition, since the plastic film can be easily inspected for defects, the resin impermeability can be reliably satisfied. Furthermore, by using a thin plastic film, it can be easily and accurately arranged along the outer shape of the block body.
本発明ではとくにプラスチックフィルムとして熱収縮フィルムを用いるので、単に加熱するだけで、容易にかつ精度よくフィルムをブロック体の外形に沿わせることができる。この場合、上記熱収縮フィルムにブロック体を内包した状態で、上記熱収縮フィルムを熱収縮させることでブロック体に容易にかつ精度よく沿わせることができる。 In the present invention, a heat shrink film is particularly used as the plastic film. Therefore , the film can be easily and accurately conformed to the outer shape of the block body simply by heating. In this case, it is possible to easily and accurately follow the block body by heat shrinking the heat shrink film in a state where the block body is included in the heat shrink film.
このように、本発明に係る中空繊維強化プラスチックの製造方法によれば、固体粒子の水溶性粘着剤による結合によりブロック体を形成することにより、要求に応じた種々の形状の中子を高精度でかつ高剛性にてしかも軽量に作製することができる。また、ブロック体を樹脂不浸透性の膜で覆うことにより、中子に関して、中子形成用の表面コート材、成形用の樹脂の両方に対して不浸透性能を達成でき、中子内への樹脂浸透の問題の発生を防止できるとともに、成形後に中子内から固体粒子を容易に取り出すことが可能になる。樹脂不浸透性の膜としてプラスチックフィルム、とくに薄いフィルム、中でも熱収縮フィルムを使用するので、比較的複雑な形状であっても、中子を一層高精度でかつ高剛性にてしかも軽量に作製することができる。また、中子内の空隙量を大きく設定できるため、軽い中子に形成でき、取扱い性に極めて優れている。また、ブロック体を形成する固体粒子の結合に水溶性粘着剤を用いているので、有機溶剤を用いることなく水系溶媒で簡単に固体粒子の結合を解除して外部に排出できるようになり、操作の容易化をはかることができるとともに、作業環境面でも優れている。さらに、排出の容易化、中子内への樹脂不浸透化とも相まって、取り出した固体粒子を容易に再使用することが可能になる。これの結果、所望の中空繊維強化プラスチックを確実にかつ効率よく、高い生産性をもって製造できるようになる。 As described above, according to the method for producing a hollow fiber reinforced plastic according to the present invention, the block body is formed by bonding the solid particles with the water-soluble pressure-sensitive adhesive, so that the cores having various shapes according to the request can be accurately obtained. In addition, it can be manufactured with high rigidity and light weight. In addition, by covering the block with a resin-impermeable film, the core can achieve impermeability with respect to both the surface coating material for forming the core and the resin for molding. The occurrence of the resin penetration problem can be prevented, and solid particles can be easily taken out from the core after molding. A plastic film as a resin impermeable film, particularly thin film, among others Runode use the heat-shrinkable film, even relatively complex shape, making yet lightweight a core in and high rigidity even higher precision can do. Moreover, since the amount of voids in the core can be set large, it can be formed into a light core and is extremely excellent in handleability. In addition, since a water-soluble adhesive is used to bond the solid particles forming the block body, the solid particles can be easily released with an aqueous solvent and discharged to the outside without using an organic solvent. Can be facilitated and the working environment is also excellent. Furthermore, coupled with the ease of discharge and the impermeability of the resin into the core, the extracted solid particles can be easily reused. As a result, a desired hollow fiber reinforced plastic can be manufactured reliably and efficiently with high productivity.
