また、前記プリプレグは、炭素繊維にエポキシ樹脂を含浸させたものであることを特徴とする。 Further, the prepreg is characterized in that carbon fiber is impregnated with an epoxy resin.
本発明の超高分子量ポリエチレン繊維織物の接合方法によれば、超高分子量ポリエチレン繊維織物同士を簡単な工程で強固に接合することができる。 According to the method for joining ultrahigh molecular weight polyethylene fiber fabrics of the present invention, ultrahigh molecular weight polyethylene fiber fabrics can be firmly joined together in a simple process.
本発明の超高分子量ポリエチレン繊維織物の接合方法は、超高分子量ポリエチレン繊維からなる織物と、プリプレグとを、交互に重ね合わせる重ね合わせ工程と、前記織物と前記プリプレグとを縫合する縫合工程と、前記プリプレグを構成する熱硬化性樹脂を熱硬化させる熱硬化工程とを備えたものである。 The method for joining ultra high molecular weight polyethylene fiber fabrics of the present invention includes a superimposing step of alternately superimposing a fabric composed of ultra high molecular weight polyethylene fibers and a prepreg, and a suturing step of suturing the fabric and the prepreg, And a thermosetting step of thermosetting the thermosetting resin constituting the prepreg.
本発明の超高分子量ポリエチレン繊維織物の接合方法は、１００〜７００万の分子量を有する超高分子量ポリエチレン繊維からなる織物を対象としている。超高分子量ポリエチレン繊維は、国内では、東洋紡績株式会社から「ダイニーマ（登録商標）」という商品名で販売されている。 The method for joining ultra high molecular weight polyethylene fiber fabrics of the present invention is intended for fabrics made of ultra high molecular weight polyethylene fibers having a molecular weight of 1 to 7 million. Ultra high molecular weight polyethylene fibers are sold in Japan under the trade name “Dyneema (registered trademark)” by Toyobo Co., Ltd.
はじめの重ね合わせ工程において、超高分子量ポリエチレン繊維からなる織物と、プリプレグとを、交互に重ね合わせる。ここで使用されるプリプレグは、繊維に熱硬化性樹脂を含浸させたものである。プリプレグを構成する繊維としては、カーボン繊維、ガラス繊維、アラミド繊維などが挙げられる。また、プリプレグを構成する熱硬化樹脂としては、特定の樹脂に限定されるものではなく、公知のものが使用可能であるが、例えば、エポキシ樹脂、ポリエステル樹脂などが用いられる。また、織物とプリプレグは、交互に重ね合わせればよく、織物−プリプレグ−織物と３層に重ねてもよく、織物−プリプレグ−織物−プリプレグと４層に、プリプレグ−織物−プリプレグ−織物−プリプレグと５層、或いは、プリプレグ−織物−プリプレグ−プリプレグ−織物−プリプレグと６層に重ねてもよい。さらに、プリプレグとしては、織物と重ね合わせる際に繊維に熱硬化性樹脂を含浸させたもの、又は織物と重ね合わせる際に繊維に熱硬化性樹脂を塗布したものを使用してもよい。或いは、例えば、織物−熱硬化性樹脂−繊維−熱硬化性樹脂−織物と重ねて、繊維に熱硬化性樹脂を含浸させてプリプレグとしてもよい。また、例えば、織物−熱硬化性樹脂−繊維−熱硬化性樹脂−織物と重ねる場合には、織物に熱硬化性樹脂を塗布してもよい。 In the first overlapping step, the woven fabric made of ultrahigh molecular weight polyethylene fibers and the prepreg are alternately overlapped. The prepreg used here is one in which a fiber is impregnated with a thermosetting resin. Examples of the fiber constituting the prepreg include carbon fiber, glass fiber, and aramid fiber. Moreover, as a thermosetting resin which comprises a prepreg, it is not limited to a specific resin, A well-known thing can be used, For example, an epoxy resin, a polyester resin, etc. are used. In addition, the woven fabric and the prepreg may be alternately stacked, and the woven fabric-prepreg-woven fabric may be stacked in three layers. Five layers or prepreg-woven fabric-prepreg-prepreg-woven fabric-prepreg and 6 layers may be stacked. Further, as the prepreg, a fiber in which a fiber is impregnated with a thermosetting resin when being overlapped with a woven fabric, or a fiber in which a thermosetting resin is applied when being overlapped with a woven fabric may be used. Alternatively, for example, a fabric-thermosetting resin-fiber-thermosetting resin-woven fabric may be overlapped and a fiber may be impregnated with a thermosetting resin to form a prepreg. Further, for example, in the case of overlapping with a woven fabric-thermosetting resin-fiber-thermosetting resin-woven fabric, a thermosetting resin may be applied to the woven fabric.
つぎの縫合工程において、重ね合わせ工程において重ね合わせた織物とプリプレグとを縫合する。この縫合はミシン等を用いて行うことができ、縫合に用いる糸の種類は特に限定されず、天然繊維、合成繊維のいずれでも用いることができる。また、金属製の糸や、ステープラーなどの金具を用いて縫合してもよい。 In the next stitching step, the woven fabric and the prepreg overlapped in the overlapping step are stitched. This stitching can be performed using a sewing machine or the like, and the type of thread used for stitching is not particularly limited, and any of natural fibers and synthetic fibers can be used. Moreover, you may sew using metal thread | threads, metal fittings, such as a stapler.
熱硬化工程においては、縫合工程において織物と縫合されたプリプレグの熱硬化性樹脂を熱硬化させる。熱硬化性樹脂を熱硬化させる際には、織物とプリプレグを密着させるのが好ましく、織物とプリプレグを密着させるために圧力を加えなから加熱するのが好ましい。 In the thermosetting step, the thermosetting resin of the prepreg stitched with the fabric in the suturing step is thermoset. When thermosetting the thermosetting resin, it is preferable that the woven fabric and the prepreg are in close contact with each other, and it is preferable to heat the curable resin and the prepreg without applying pressure.
以上の工程により、超高分子量ポリエチレン繊維織物同士を簡単な工程で強固に接合することができる。 By the above process, ultra high molecular weight polyethylene fiber fabrics can be firmly joined to each other by a simple process.
