産業上の利用分野
本発明は繊維強化熱硬化性樹脂よりなる複合材料を用い
たパイプの成形方法に関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method of forming a pipe using a composite material made of fiber-reinforced thermosetting resin.
従来の技術
熱硬化性樹脂の成形には一般に加熱加圧を要する。した

金型が非常に複雑となり、またパイプ内面に接する金型
には離型を容易にするために充分なテーパを付するので
細い直管は成形が困難である等、従来のパイプ成形方法
には種々の問題があった。BACKGROUND OF THE INVENTION Molding thermosetting resins generally requires heating and pressurization. Therefore, in order to mold a pipe using fiber-reinforced thermosetting resin, the mold is very complicated in terms of the removal of the mold inside the pipe, the pressurizing structure, etc., and the mold that is in contact with the inner surface of the pipe is Conventional pipe forming methods have had various problems, such as the difficulty in forming thin straight pipes because they are sufficiently tapered to facilitate mold release.
発明が解決しようとする問題点
本発明の目的は、繊維強化熱硬化性樹脂素材を積層して
パイプを成形する際に、離型用のテーパや加圧装置が不
要で、きわめて簡易な成形型を用いて成形し得るパイプ
の製造方法を提供することにある。Problems to be Solved by the Invention The purpose of the present invention is to provide an extremely simple mold that eliminates the need for a taper or pressure device for mold release when forming a pipe by laminating fiber-reinforced thermosetting resin materials. An object of the present invention is to provide a method for manufacturing a pipe that can be molded using.
問題点を解決するための手段
本発明は、熱膨張係数が大で離型性に富む芯材に未硬化
状態の繊維強化熱硬化性樹脂素材を積層し、積層後に外
周面を剛性大なる金属製治具により密包したのち加熱し
て繊維強化熱硬化性樹脂素材を硬化せしめ、冷却後に収
縮した芯材を引き抜くことを特徴とする。Means for Solving the Problems The present invention involves laminating an uncured fiber-reinforced thermosetting resin material onto a core material that has a large coefficient of thermal expansion and excellent mold releasability, and after lamination, the outer peripheral surface is made of a highly rigid metal. The method is characterized in that the fiber-reinforced thermosetting resin material is hardened by heating after being sealed in a manufacturing jig, and the shrunken core material is pulled out after cooling.
作 用
前記芯材は金属性治具より熱膨張係数が大で離型性に富
むので、これに積層した前記樹脂製材は加熱による芯材
の熱膨張力により治具内面との間に加圧された状態で熱
硬化する。この際発生ガスは治具の両端開放部から放出
されるから、ガス抜き操作は不要である。所定加熱時間
後に冷却すると、芯材は収縮して硬化した樹脂の内面か
ら離れるから、芯材を容易に引き抜くことができる。ま
た硬化樹脂はその収縮により治具から容易に離型し得る
。Function: The core material has a larger coefficient of thermal expansion and better mold releasability than the metal jig, so the resin material laminated thereon is pressurized with the inner surface of the jig due to the thermal expansion force of the core material due to heating. Cures under heat. At this time, the generated gas is released from the open ends of the jig, so there is no need to perform a degassing operation. When cooled after a predetermined heating time, the core material shrinks and separates from the inner surface of the hardened resin, so that the core material can be easily pulled out. Furthermore, the cured resin can be easily released from the jig due to its shrinkage.
実 施 例
図において、１は例えばテフロン、シリコン等の熱膨張
係数が大で離型性に富む円筒状芯材で、これに繊維強化
材たる基材に乾式法又は湿式法によりフェノール樹脂を
付着させた素材を密゛に巻き付けて未硬化の樹脂層２を
形成し、その外面に半円形断面の丈夫な金属製割形治具
３゜３を当てて締結具４により締めつけ支持し、これを
適当な加熱装置を用いて加熱し、樹脂層２を硬化させる
。In the example diagram, 1 is a cylindrical core material, such as Teflon or silicone, which has a large coefficient of thermal expansion and is highly releasable, and a phenol resin is attached to the base material, which is a fiber reinforcement material, by a dry method or a wet method. The uncured resin layer 2 is formed by tightly wrapping the material, and a durable split metal jig 3 with a semicircular cross section is applied to the outer surface of the resin layer 2, which is then tightened and supported by a fastener 4. The resin layer 2 is cured by heating using a suitable heating device.
所定時間加熱した後冷却すると、硬化した樹脂層２は収
縮して治具３から離脱し、芯材１は更に収縮して樹脂層
２の内面から離れるので、これを引き１友けば繊維強化
熱硬化性樹脂バイブが得られる。When cooled after heating for a predetermined time, the hardened resin layer 2 contracts and separates from the jig 3, and the core material 1 further contracts and separates from the inner surface of the resin layer 2. A thermosetting resin vibe is obtained.

表面は治具内面に圧接されてしわ等がない美麗な外観を
呈し、表面の仕上げ加工が不要である等の効果がある。Effects of the Invention The present invention has the above-mentioned configuration, and the structure of the mold is extremely simple, and since the resin layer is pressurized and hardened by the thermal expansion force of the core material, a pressurizing device is not required. The surface of the vibrator is pressed against the inner surface of the jig, giving it a beautiful appearance with no wrinkles, etc., and has the advantage of eliminating the need for surface finishing.
