Abstract
Description
本発明は、プリプレグを貼り合わせてなる炭素繊維強化プラスチック材料及びそれを利用したプリプレグ成形品の製造方法に関するものである。 The present invention relates to a carbon fiber reinforced plastic material obtained by laminating a prepreg and a method for producing a prepreg molded product using the same.
従来、繊維基材としてノンクリンプ織物（ＮＣＦ；ＮＯＮ ＣＲＩＭＰ ＦＡＢＲＩＣ）が頻繁に使用されている。ノンクリンプ織物は、図５に示すように、多方向に積層した繊維の束１をナイロンやポリエステル等の高分子の糸２によって縛ったものである。このため、繊維織物とは構造が異なり、繊維のうねりが非常に小さいので、強化繊維の特性を有効に発揮することができるとともに、成形時には樹脂の流れが円滑になり成形性が良く、また取扱いも容易であるといった利点を有している。
このようなノンクリンプ織物については、例えば、特許文献１に開示されている。
Conventionally, a non-crimp fabric (NCF; NON CRIMP FABRIC) is frequently used as a fiber base material. As shown in FIG. 5, the non-crimp woven fabric is a bundle of fibers 1 laminated in multiple directions and is bound by a high-molecular yarn 2 such as nylon or polyester. For this reason, the structure of fiber fabric is different and the undulation of the fiber is very small, so that the properties of the reinforcing fiber can be exhibited effectively, the flow of the resin is smooth during molding, and the moldability is good. Has the advantage of being easy.
Such a non-crimp fabric is disclosed in Patent Document 1, for example.
しかしながら、繊維の束１を縛る糸２を構成する樹脂の成分が、繊維の束１に含浸された熱可塑性樹脂と異なる場合には糸２で縛ったときの強度が低下する恐れがある。
また、繊維の束１に含浸された熱可塑性樹脂と同じ樹脂では糸２に加工することできない場合や、加工できたとしても強度的に弱く縛る糸２として使用するには十分ではない場合もある。
However, when the resin component constituting the yarn 2 that binds the fiber bundle 1 is different from the thermoplastic resin impregnated in the fiber bundle 1, the strength when the fiber bundle 1 is bound with the yarn 2 may be reduced.
Further, the same resin as the thermoplastic resin impregnated in the fiber bundle 1 may not be processed into the yarn 2, or even if processed, it may not be sufficient for use as the yarn 2 that binds weakly in strength. .
なお、特許文献１に記載の発明は、たて方向およびよこ方向を含む二方向以上に炭素繊維糸条が配列している導電性織物で、たて方向およびよこ方向に金属線が炭素繊維糸条と並行に配列され、平面上の任意の２５ｃｍ2におけるたて方向の金属線と、よこ方向の金属線とが互いに７０％以上で交錯され、導電性織物のカバーファクターが９０〜１００％であるようにすることによって、たて方向の金属線とよこ方向の金属線との交錯点を多く存在させることができ、これにより、導電性，力学特性および表面品位に優れる複合材料を生産性良く得ることができるというものである。 The invention described in Patent Document 1 is an electrically conductive woven fabric in which carbon fiber yarns are arranged in two or more directions including the warp direction and the weft direction, and the metal wires are carbon fiber yarns in the warp direction and the weft direction. The metal wires in the vertical direction and the metal wires in the horizontal direction at an arbitrary 25 cm 2 on the plane arranged in parallel with the stripes are crossed at 70% or more, and the cover factor of the conductive fabric is 90-100%. As a result, there can be many intersections between the vertical metal wires and the horizontal metal wires, thereby obtaining a composite material excellent in conductivity, mechanical properties and surface quality with high productivity. It can be done.
しかし、炭素繊維糸条が配列している導電性織物だけからなるものではなく、金属線が設けられているので、上述したように両者の材質によっては強度が低下するといった問題がある。また、たて方向の炭素繊維糸条とよこ方向の炭素繊維糸条が織られてなるものであるので、金属線を使用したとしても強度が十分であるとはいえない。 However, there is a problem in that the strength is lowered depending on the material of both because the metal wire is provided instead of only the conductive fabric in which the carbon fiber yarns are arranged. Further, since the carbon fiber yarns in the vertical direction and the carbon fiber yarns in the transverse direction are woven, even if a metal wire is used, it cannot be said that the strength is sufficient.
そこで、本発明の目的とするところは、二つのプリプレグについて織りを入れることなく、強い力で貼り合わせることのできる炭素繊維強化プラスチック材料を提供することにある。 Accordingly, an object of the present invention is to provide a carbon fiber reinforced plastic material that can be bonded with a strong force without weaving two prepregs.

前記第１プリプレグ群の上に交差するように重ねられ、他方向に延びるヤーンプリプレグを複数枚、前記他方向に直交する方向に隙間なく並設され、前記第１プリプレグ群に対して超音波融着により一体化されてなる第２プリプレグ群を備え、織りを入れないようにしたことを特徴にする。

The second prepreg group is integrated by wearing, and is characterized in that no weaving is provided.
なお、上記ＵＤテーププリプレグ（１０ａ，２０ａ）及びヤーンプリプレグには、熱可塑性樹脂をマトリクス樹脂として繊維基材に半含浸させた柔軟性に優れた、いわゆるＵＤテープセミプレグ及びヤーンセミプレグも含まれることを意味する。 The UD tape prepregs (10a, 20a) and yarn prepregs include so-called UD tape semipregs and yarn semipregs excellent in flexibility in which a fiber base material is semi-impregnated with a thermoplastic resin as a matrix resin. means.
また本発明は、前記第１プリプレグ群（１０）に並設された各々のＵＤテーププリプレグ（１０ａ）又はヤーンプリプレグは、前記第２プリプレグ群（２０）に並設されたすべてのＵＤテーププリプレグ（２０ａ）又はヤーンプリプレグに直接、前記超音波融着されてなることを特徴にする。 Further, according to the present invention, each of the UD tape prepregs (10a) or yarn prepregs arranged in parallel with the first prepreg group (10) is connected to all the UD tape prepregs (20) arranged in parallel with the second prepreg group (20). 20a) or the yarn prepreg is directly fused with the ultrasonic wave.

本発明の炭素繊維強化プラスチック材料によれば、一方向に延びるＵＤテーププリプレグを複数枚、一方向に直交する方向に隙間なく並設されてなる第１プリプレグ群に、他方向に延びるＵＤテーププリプレグを複数枚、他方向に直交する方向に隙間なく並設されてなる第２プリプレグ群が重ねられ、両者が超音波融着により一体化されたものであり、特に織りを入れないようにしたので、従来例で示したように、交差するプリプレグを縛る糸を設ける必要はない。
したがって、糸の成分をプリプレグに含浸された熱可塑性樹脂と同じ樹脂で構成する点について何ら考慮する必要はない。
According to the carbon fiber reinforced plastic material of the present invention, a plurality of UD tape prepregs extending in one direction, a UD tape prepreg extending in the other direction in a first prepreg group arranged in parallel in a direction orthogonal to the one direction without a gap. Since the second prepreg group, which is arranged in parallel in the direction orthogonal to the other direction without any gaps, is stacked, and both are integrated by ultrasonic fusion. As shown in the conventional example, it is not necessary to provide a yarn for binding the crossing prepregs.
Therefore, there is no need to consider at all that the yarn component is made of the same resin as the thermoplastic resin impregnated in the prepreg.
また、本発明によれば、特に織りが入っていないため、第１プリプレグ群と第２プリプレグ群を重ねて一体化した場合に強度が低下することはない。また、第１プリプレグ群と第２プリプレグ群が重ねられ超音波融着により、それらプリプレグの樹脂自身で融着しているため不純物が混入することもなく、それによる強度低下も生じない。 Further, according to the present invention, since there is no particular weaving, the strength does not decrease when the first prepreg group and the second prepreg group are stacked and integrated. In addition, since the first prepreg group and the second prepreg group are overlapped and are fused by the resin of the prepreg itself by ultrasonic fusion, impurities are not mixed in, and the strength is not reduced.
なお、第１プリプレグ群のＵＤテーププリプレグが延びる方向と第２プリプレグ群のＵＤテーププリプレグが延びる方向は横方向と縦方向で直交するようにしてもよいが、必ずしも両者は９０°（度）で交わるものでなくてもよい。 The direction in which the UD tape prepreg in the first prepreg group extends and the direction in which the UD tape prepreg in the second prepreg group extend may be orthogonal to each other in the horizontal direction and the vertical direction, but both of them are necessarily 90 ° (degrees). It does not have to intersect.
また、第１プリプレグ群と第２プリプレグ群がそれぞれＵＤテーププリプレグから構成されたものに限らず、これにかえて、ヤーンプリプレグで構成されたものであっても上述した同様の効果が得られる。 In addition, the first prepreg group and the second prepreg group are not limited to those composed of UD tape prepregs, but the same effects as described above can be obtained even if they are composed of yarn prepregs.
また、本発明によれば、第１プリプレグ群に並設された各々のＵＤテーププリプレグ又はヤーンプリプレグは、第２プリプレグ群に並設されたすべてのＵＤテーププリプレグ又はヤーンプリプレグに直接、超音波融着されてなるようにしたので、十分な強度で一体化されている。 Further, according to the present invention, each UD tape prepreg or yarn prepreg arranged in parallel in the first prepreg group is directly ultrasonically bonded to all the UD tape prepregs or yarn prepregs arranged in parallel in the second prepreg group. Since it is worn, it is integrated with sufficient strength.
また、本発明のプリプレグ成形品の製造方法は、上述したように、第１プリプレグ群と第２プリプレグ群を重ねて超音波融着で一体化してなる炭素繊維強化プラスチック材料を、１枚で、あるいは、複数枚重ねたものを金型にセットして加熱加圧処理を施し型成形するものであるので、第１プリプレグ群と第２プリプレグ群は十分な強度で仮固定され、金型にセットするとき容易にずれることはなく、安定した状態で型成形される。 In addition, as described above, the method for producing a prepreg molded product of the present invention includes a single carbon fiber reinforced plastic material formed by superimposing the first prepreg group and the second prepreg group by ultrasonic fusion, Alternatively, since a plurality of stacked sheets are set in a mold and subjected to heat and pressure treatment to be molded, the first prepreg group and the second prepreg group are temporarily fixed with sufficient strength and set in the mold. When it does, it does not shift easily and is molded in a stable state.
なお、本発明の炭素繊維強化プラスチック材料のように、ＵＤテーププリプレグ又はヤーンプリプレグからなる第１プリプレグ群と第２プリプレグ群を重ねて超音波融着で一体化して、特に織りを入れないようにした点は、上述した特許文献１には全く記載されていない。 In addition, like the carbon fiber reinforced plastic material of the present invention, the first prepreg group and the second prepreg group made of UD tape prepreg or yarn prepreg are overlapped and integrated by ultrasonic fusion so as not to be particularly woven. This point is not described at all in the above-mentioned Patent Document 1.
図面を参照して本発明の実施形態に係る炭素繊維強化プラスチック材料及びそれを利用したプリプレグ成形品の製造方法について説明する。
本実施形態の炭素繊維強化プラスチック材料１００は、図１に示すように、複数枚（特に枚数に限定されるものではないが、ここでは１８枚）のＵＤテーププリプレグ１０ａからなる第１プリプレグ群１０と、同じく複数枚（特に枚数に限定されるものではないが、ここでは１０枚）のＵＤテーププリプレグ２０ａからなる第２プリプレグ群２０とが交差するように重ねられるとともに、両者は特に織りを入れない状態で固定されてなる。
A carbon fiber reinforced plastic material according to an embodiment of the present invention and a method for producing a prepreg molded product using the same will be described with reference to the drawings.
As shown in FIG. 1, the carbon fiber reinforced plastic material 100 of the present embodiment is a first prepreg group 10 composed of a plurality of UD tape prepregs 10a (in this case, 18 sheets are not limited to the number in particular). Similarly, the second prepreg group 20 consisting of a plurality of UD tape prepregs 20a (which is not particularly limited to 10 but here is 10) is overlapped so as to intersect with each other, and both are particularly woven. It is fixed in the absence.
第１プリプレグ群１０は、一方向、例えば横方向に延びるＵＤテーププリプレグ１０ａを複数枚、一方向に直交する方向、図１では、横方向に直交する縦方向に隙間なく並設されたものであって、隣接するＵＤテーププリプレグ１０ａ間は接着されていない。
また、第２プリプレグ群２０は、他方向、例えば縦方向に延びるＵＤテーププリプレグ２０ａを複数枚、他方向に直交する方向、図１では、縦方向に直交する縦方向に隙間なく並設されたものであって、隣接するＵＤテーププリプレグ２０ａ間も接着されていない。 なお、本実施形態でいうＵＤテーププリプレグ１０ａ，２０ａには、熱可塑性樹脂をマトリクス樹脂として繊維基材に半含浸させてなり柔軟性に優れた、いわゆるＵＤテープセミプレグも含まれる。
The first prepreg group 10 is a plurality of UD tape prepregs 10a extending in one direction, for example, in the horizontal direction, arranged in parallel in the direction orthogonal to the one direction, in FIG. 1, in the vertical direction orthogonal to the horizontal direction. Thus, the adjacent UD tape prepregs 10a are not bonded.
In addition, the second prepreg group 20 is arranged in parallel in the other direction, for example, a plurality of UD tape prepregs 20a extending in the longitudinal direction, in a direction perpendicular to the other direction, in FIG. 1, in the longitudinal direction perpendicular to the longitudinal direction. The adjacent UD tape prepregs 20a are not bonded. Note that the UD tape prepregs 10a and 20a referred to in this embodiment include so-called UD tape semi-pregs that are excellent in flexibility by semi-impregnating a fiber base material with a thermoplastic resin as a matrix resin.
そして、第１プリプレグ群１０の上に重ねられた第２プリプレグ群２０は、第１プリプレグ群１０に対して超音波融着による手段のみによって一体化されている。
超音波融着は、超音波熱融着又は超音波溶着とも呼ばれ、図示を省略した一般的な超音波融着機を使用して、微細な超音波振動と加圧力によってＵＤテーププリプレグ１０ａ及びＵＤテーププリプレグ２０ａを構成する熱可塑性樹脂を瞬時に溶融して接合するもので、図１に示すように、複数の超音波融着点３０が離散的に形成されている。
The second prepreg group 20 stacked on the first prepreg group 10 is integrated with the first prepreg group 10 only by means of ultrasonic fusion.
The ultrasonic fusion is also called ultrasonic thermal fusion or ultrasonic fusion, and a general ultrasonic fusion machine (not shown) is used, and the UD tape prepreg 10a and the UD tape prepreg 10a and The thermoplastic resin constituting the UD tape prepreg 20a is instantaneously melted and joined, and as shown in FIG. 1, a plurality of ultrasonic fusion points 30 are discretely formed.
本実施形態例では、第１プリプレグ群１０に並設された各々１８枚のＵＤテーププリプレグ１０ａは、第２プリプレグ群２０に並設されたすべての、すなわち、１０枚のＵＤテーププリプレグ２０ａに規則正しく等間隔で直接、超音波融着されてなる。よって、ここでは、１８０個（＝１８×１０）の超音波融着点３０が形成されている。 In this embodiment, each of the 18 UD tape prepregs 10a arranged in parallel in the first prepreg group 10 is regularly arranged on all, ie, 10 UD tape prepregs 20a arranged in parallel in the second prepreg group 20. The ultrasonic fusion is performed directly at equal intervals. Therefore, 180 (= 18 × 10) ultrasonic fusion points 30 are formed here.
このように、第１プリプレグ群１０と第２プリプレグ群２０は、超音波融着による固定手段だけで一体化されたものであり、特に織りを入れないようにしたので、従来例で示したように、交差するプリプレグを縛る糸を設ける必要はなく、簡単かつ強度的にも強く固定することができる。 In this way, the first prepreg group 10 and the second prepreg group 20 are integrated only by the fixing means by ultrasonic fusion, and are not particularly woven, so as shown in the conventional example Further, it is not necessary to provide a thread for binding the crossing prepregs, and it can be easily and strongly fixed.
また、本実施形態によれば、特に織りが入っていないため、第１プリプレグ群１０と第２プリプレグ群２０を重ねて一体化した場合に強度が低下することはない。また、第１プリプレグ群１０と第２プリプレグ群２０が重ねられ超音波融着により、それらプリプレグの樹脂自身で融着しているため不純物が混入することもなく、それによる強度低下も生じない。 Further, according to the present embodiment, since there is no particular weaving, the strength does not decrease when the first prepreg group 10 and the second prepreg group 20 are overlapped and integrated. Further, since the first prepreg group 10 and the second prepreg group 20 are overlapped and are fused by the resin of the prepregs by ultrasonic fusion, impurities are not mixed in, and the strength is not reduced.
そして、このように構成された炭素繊維強化プラスチック材料１００を利用してプリプレグ成形品を製造するには、炭素繊維強化プラスチック材料１００を１枚（単体）又は複数枚重ねたものを金型（図示しない）にセットして加熱加圧処理を施すことで、目的にする成形品が型成形される。
このとき、第１プリプレグ群１０と第２プリプレグ群２０は超音波融着によって十分な強度で仮固定されているので、金型にセットするとき容易にずれることはなく、安定した状態で型成形加工を施すことができる。
In order to manufacture a prepreg molded product using the carbon fiber reinforced plastic material 100 configured in this manner, one (single) or a plurality of stacked carbon fiber reinforced plastic materials 100 is used as a mold (illustrated). The target molded product is molded by applying the heat and pressure treatment.
At this time, since the first prepreg group 10 and the second prepreg group 20 are temporarily fixed with sufficient strength by ultrasonic fusion, they are not easily displaced when set in a mold, and are molded in a stable state. Processing can be performed.
なお、本発明の実施形態では、超音波融着については超音波融着機を使用して複数の超音波融着点３０を離散的に形成するようにしたが、超音波融着点の形状は特に限定されるものではなく、例えば、図２に示したように、超音波ミシン（図示しない）を使用して第２プリプレグ群２０に並設されたＵＤテーププリプレグ２０ａのそれぞれを縦方向に二分割するステッチ状のミシン目を超音波融着点３１として形成するようにしてもよい。 In the embodiment of the present invention, with respect to ultrasonic fusion, a plurality of ultrasonic fusion points 30 are discretely formed using an ultrasonic fusion machine. Is not particularly limited. For example, as shown in FIG. 2, each of the UD tape prepregs 20a arranged in parallel with the second prepreg group 20 using an ultrasonic sewing machine (not shown) is arranged in the vertical direction. You may make it form the stitch-like perforation which divides into two as the ultrasonic fusion point 31. FIG.
また、超音波融着点３０の数については、図１では、第１プリプレグ群１０に並設された各々のＵＤテーププリプレグ１０ａが、第２プリプレグ群２０に並設されたすべてのＵＤテーププリプレグ２０ａに超音波融着されるように、一つのＵＤテーププリプレグ１０ａに対してそれに交差するＵＤテーププリプレグ２０ａの数分（ここでは、１８個分）の超音波融着点３０をすべての交差位置に形成するようにしたが、第１プリプレグ群１０と第２プリプレグ群２０を安定して固定することができれば超音波融着点３０の数は限定されるものではなく、例えば、図３に示したように、一つ置きの交差位置に超音波融着点３０を形成するとともに隣接するＵＤテーププリプレグ１０ａでは超音波融着点３０の位置をずらして形成することもできる。 As for the number of ultrasonic fusion points 30, in FIG. 1, each UD tape prepreg 10 a arranged in parallel with the first prepreg group 10 is replaced with all UD tape prepregs arranged in parallel with the second prepreg group 20. The ultrasonic fusion points 30 corresponding to several UD tape prepregs 20a intersecting with one UD tape prepreg 10a are connected to all the intersection positions so as to be ultrasonically fused to 20a. However, the number of ultrasonic fusion points 30 is not limited as long as the first prepreg group 10 and the second prepreg group 20 can be stably fixed. For example, as shown in FIG. As described above, the ultrasonic fusion points 30 can be formed at every other crossing position, and the ultrasonic fusion points 30 can be shifted in the adjacent UD tape prepreg 10a. .
また、本発明の実施形態では、第１プリプレグ群１０のＵＤテーププリプレグ１０ａが延びる方向と第２プリプレグ群２０のＵＤテーププリプレグ２０ａが延びる方向を横方向と縦方向で直交するようにしたが、例えば、図３に示したように、必ずしも両者は９０°（度）で交わるものでなくてもよい。く、 In the embodiment of the present invention, the direction in which the UD tape prepreg 10a of the first prepreg group 10 extends and the direction in which the UD tape prepreg 20a of the second prepreg group 20 extends are orthogonal to each other in the horizontal direction and the vertical direction. For example, as shown in FIG. 3, the two do not necessarily intersect at 90 degrees (degrees). The
また、本実施形態では、第１プリプレグ群１０と第２プリプレグ群２０がそれぞれＵＤテーププリプレグから構成されたものであったが、これにかえて、ヤーンプリプレグ（熱可塑性樹脂をマトリクス樹脂として繊維基材に半含浸させた柔軟性に優れた、いわゆるヤーンセミプレグも含まれる。）で構成されたものであっても上述した同様の効果が得られる。 In the present embodiment, the first prepreg group 10 and the second prepreg group 20 are each composed of a UD tape prepreg, but instead of this, a yarn prepreg (a fiber base using a thermoplastic resin as a matrix resin) is used. The same effect as described above can be obtained even when the material is composed of a so-called yarn semi-preg excellent in flexibility semi-impregnated into a material.
