　本発明は、金属―プリプレグ複合体及びそれから得られる金属－繊維強化樹脂複合成形体に関する。 The present invention relates to a metal-prepreg composite and a metal-fiber reinforced resin composite molding obtained therefrom.
　炭素繊維等を用いる繊維強化樹脂は、高い強度と軽さを併せ持つ材料のため、様々な用途に使用されている。例えば、自動車分野では、鋼鉄に代わる新材料として期待されている。しかし、繊維強化樹脂は、現時点で鋼鉄等に比べ高価格であるため、製品の価格を抑えようとする場合は、繊維強化樹脂を多く用いることが難しい。そこで、鋼鉄等の金属と、繊維強化樹脂との複合体を用いることにより、材料の軽量化を実現しながらも、価格を抑えることができる。 Fiber reinforced resins that use carbon fiber, etc. are used in a variety of applications because they are materials that combine high strength and lightness. For example, in the automobile field, it is expected as a new material to replace steel. However, fiber reinforced resin is currently more expensive than steel and the like, so it is difficult to use a large amount of fiber reinforced resin when trying to keep the price of the product down. Therefore, by using a composite of a metal such as steel and a fiber-reinforced resin, it is possible to reduce the cost while realizing weight reduction of the material.

　また、例えば、特許文献２には、金属と有機高分子物質等を接着させる場合に優れた接着力を発揮する金属の表面処理方法として、金属の表面に被膜形成を伴う化学エッチング処理を行い、そののちシランカップリング剤を用いた処理、又は塗布型クロメート処理を行う方法が開示されている（特許文献２）。

　これらの従来の技術は、接着力の向上を図るため、凸凹によるアンカー効果を利用する粗面化処理や、金属と樹脂とを接着する場合に優れた接着力を発揮する処理を金属表面に施しているが、それらの処理は制御が困難であったり、多工程であったりして時間やコストがかかる。 As a metal-resin composite, for example, in Patent Document 1, as a method for manufacturing a composite of a resin member and a metal member, a metal part subjected to a surface treatment by chemical etching is subjected to a resin injection method. is disclosed (Patent Document 1).
Further, for example, Patent Document 2 describes a method for surface treatment of metal that exhibits excellent adhesive strength when bonding a metal to an organic polymer substance or the like. A method is disclosed in which a treatment using a silane coupling agent or a coating-type chromate treatment is then performed (Patent Document 2).
Further, for example, in Patent Document 3, an adhesive layer having a modified polypropylene resin in which a polar group is introduced is formed on a surface treatment film provided on the surface of a base material made of an aluminum alloy, and made compatible with polypropylene. and a method of joining by an anchor effect is disclosed (Patent Document 3).
In order to improve the adhesive strength, these conventional techniques apply a surface roughening treatment that utilizes the anchor effect of unevenness and a treatment that exhibits excellent adhesive strength when bonding metal and resin to the metal surface. However, these processes are difficult to control and involve multiple processes, which are time-consuming and costly.

Aluminum mesh 2 as an adhesion reinforcing layer is inserted between prepreg 1 and adhesive sheet 3 arranged between metal plate 4 and prepreg 1 . The aluminum mesh 2 is made of metal and has a plurality of through holes 21 .
The metal of the aluminum mesh 2 is not particularly limited as long as it is a material that can be formed by the press forming of the present invention, and various metals such as aluminum, stainless steel, iron, steel, titanium, and high tensile strength can be used.
Although the thickness of the aluminum mesh 2 is not limited, it is preferably about 0.05 to 3 mm because it can be easily formed into a desired shape by press molding.
The aluminum mesh 2 is composed of metal punching, metal mesh or metal expansion. Metal punching is a material that is processed by punching holes in a metal plate using a punching press. Metal mesh is a material in which metal wires are woven or knitted into a mesh. Metal expand is a metal plate that is mechanically stretched while making cuts in a zigzag pattern, and the cuts are made into a diamond-shaped or tortoiseshell-shaped mesh. It is a processed material.
　アルミニウムメッシュ２の主たる目的とは、金属体４とプレプレグ１との接着力を高めること、そして、金属－プリプレグ複合体Ａを加熱プレスした後の金属－繊維強化樹脂複合成形体の繊維強化樹脂と金属体との接着力を高めることが、主たる目的である。アルミニウムメッシュ２は、従来技術として同様に接着力を高める金属表面の粗面化に近い状態であることが好ましいため、複数の貫通孔２１の面積は、０．０１～５００ｍｍ２程度の面積の貫通孔であることが好ましく、また、隣り合う貫通孔２１の距離（ここで距離とは、一方の貫通孔の縁と、隣の貫通孔の縁との間で、もっとも最短の距離をとする）は、０．５ｍｍ～５ｃｍ程度である。メッシュなら、１～１００メッシュであることが好ましい。したがって、アルミニウムメッシュ２のそのものの強度は、金属部分が多くなく、厚さも薄いため、必ずしも高くはないが、金属体４とプレプレグ１との接着力を高めるという効果を発揮する。 The main purpose of the aluminum mesh 2 is to increase the adhesive strength between the metal body 4 and the prepreg 1, and to use the fiber reinforced resin of the metal-fiber reinforced resin composite molded body after hot pressing the metal-prepreg composite A. The main purpose is to increase the adhesion to metal bodies. Since it is preferable that the aluminum mesh 2 is in a state similar to roughening of the metal surface that enhances the adhesive strength as in the conventional technology, the area of the plurality of through holes 21 is about 0.01 to 500 mm 2 It is preferably a hole, and the distance between adjacent through holes 21 (here, the distance is the shortest distance between the edge of one through hole and the edge of the adjacent through hole). is about 0.5 mm to 5 cm. The mesh is preferably 1-100 mesh. Therefore, although the strength of the aluminum mesh 2 itself is not necessarily high because it does not have many metal parts and is thin, it exhibits the effect of increasing the adhesion between the metal body 4 and the prepreg 1 .
　金属－プリプレグ複合体Ａは、炭素繊維強化樹脂のプリプレグ１と、複数の貫通孔２１を有する金属から構成されるアルミニウムメッシュ２と、接着シート３と、金属板４を積層させ、押圧することにより、接着させ、一体化させる。このとき、押圧する力は大きい必要はなく、手でおさえる程度の圧力で十分である。 The metal-prepreg composite A is obtained by laminating and pressing a carbon fiber reinforced resin prepreg 1, an aluminum mesh 2 made of metal having a plurality of through holes 21, an adhesive sheet 3, and a metal plate 4. , glue and unite. At this time, the pressing force does not need to be large, and a pressure that can be held by hand is sufficient.
　押圧したときに、接着シート３は、アルミニウムメッシュ２の貫通孔２１の中に接着成分が入り込み、アルミニウムメッシュ２に対して反対側のプリプレグ１に到達し、金属体４、アルミニウムメッシュ２、及びプリプレグ１とが接着シート３により一体化される。 When the adhesive sheet 3 is pressed, the adhesive component enters the through holes 21 of the aluminum mesh 2, reaches the prepreg 1 on the opposite side of the aluminum mesh 2, and joins the metal body 4, the aluminum mesh 2, and the prepreg. 1 are integrated by the adhesive sheet 3 .
［金属－繊維強化樹脂複合成形体］
　本発明の金属－繊維強化樹脂複合成形体は、金属－プリプレグ複合体Ａを加熱及び加圧することにより製造したものである。
　金属－繊維強化樹脂複合成形体において、加熱及び加圧により、接着シート３の接着成分と、アルミニウムメッシュ２と、プリプレグ１が一体化された複合接着強化層５となり、金属体４と複合接着強化層５とが高い接着力で接着している。このとき、プリプレグ１は、加圧及び加熱し、その後、冷却され、複合繊維強化樹脂層５を形成している。このような構成の金属－繊維強化樹脂複合成形体は、強度の高い金属と強度の高い繊維強化樹脂とを高い接着力で接着しており、従来から使用されている接着力を高める処理を行った金属－繊維強化樹脂との複合材料の代替品として利用できる。
　また、本発明において、非常に厚みのある金属体４の場合は、金属体４に複合接着強化層５を設けることができ、金属体４の強度がさらに強化されるものとなる。 [Metal-fiber reinforced resin composite molding]
The metal-fiber reinforced resin composite molded article of the present invention is produced by heating and pressurizing the metal-prepreg composite A.
In the metal-fiber reinforced resin composite molded body, the adhesive component of the adhesive sheet 3, the aluminum mesh 2, and the prepreg 1 are integrated by heating and pressing to form a composite adhesion reinforcing layer 5, and the metal body 4 and the composite adhesion strengthening. It adheres to the layer 5 with high adhesive strength. At this time, the prepreg 1 is pressurized and heated, and then cooled to form the composite fiber reinforced resin layer 5 . The metal-fiber reinforced resin composite molded body having such a structure adheres a high-strength metal and a high-strength fiber reinforced resin with high adhesive strength, and is subjected to a conventional treatment to increase the adhesive strength. It can be used as a substitute for composite materials with metal-fiber reinforced resins.
In addition, in the present invention, in the case of a very thick metal body 4, the metal body 4 can be provided with the composite adhesion reinforcing layer 5, so that the strength of the metal body 4 is further enhanced.
［プレス成型］
　本発明において金属体４が薄い金属（例えば、金属板）の場合、加熱プレスにより、所定の形状を有する金属－繊維強化樹脂複合成形体を製造することができる。プレス成形は、上金型と下金型とを用いて、両金型に挟み込まれることによって行われる。上金型及び下金型は、成形品を形成するために、所定の形状を有することができる。例えば、上金型及び下金型のプレス面に、いずれか一方には凸部、もう一方には凸部に対応する（前記凸部が入り込むことができる）凹部を設けることができる。このようにすることにより、金属－プリプレグ複合体は、凸部と凹部とに挟まれることになるため、金属－繊維強化樹脂複合成形体は、立体的な形状を有することができる。 [Press molding]
In the present invention, when the metal body 4 is a thin metal (for example, a metal plate), a metal-fiber reinforced resin composite molded body having a predetermined shape can be produced by hot pressing. Press molding is performed by sandwiching between an upper mold and a lower mold. The upper mold and lower mold can have a predetermined shape to form the molded article. For example, one of the pressing surfaces of the upper mold and the lower mold may be provided with a convex portion, and the other may be provided with a concave portion corresponding to the convex portion (into which the convex portion can be inserted). By doing so, the metal-prepreg composite is sandwiched between the protrusions and the recesses, so that the metal-fiber reinforced resin composite molded article can have a three-dimensional shape.
　本発明の金属－繊維強化樹脂複合成形体の製造においてプレス加工温度は通常１００～３５０℃である。プリプレグの樹脂が熱硬化性樹脂の場合は、１２０～１６０℃にすることができ、プリプレグの樹脂が熱可塑性樹脂の場合は、２３０～３５０℃にすることができる。 The press working temperature is usually 100 to 350°C in the production of the metal-fiber reinforced resin composite molding of the present invention. When the prepreg resin is a thermosetting resin, the temperature can be 120 to 160°C, and when the prepreg resin is a thermoplastic resin, the temperature can be 230 to 350°C.
　金属－繊維強化樹脂成形体を得るプレス加工の圧力についても、特に限定されるものではなく、通常０．１～１５ＭＰａである。 The press working pressure for obtaining the metal-fiber reinforced resin molding is also not particularly limited, and is usually 0.1 to 15 MPa.
　このようにして得られる金属－繊維強化樹脂複合成形体は、用途・形状に応じて、繊維強化樹脂を成形させたものであり、航空機、自動車等の部品、例えば、自動車用電池のケース等に使用することができる。 The metal-fiber reinforced resin composite molded body obtained in this way is obtained by molding fiber reinforced resin according to the application and shape, and can be used as parts of aircraft, automobiles, etc., such as automobile battery cases. can be used.
［接着強度の確認］
　プリプレグ１として炭素繊維含有エポキシ樹脂のプリプレグ、接着強化層２としてアルミニウムメッシュ（厚さ０．６、１０メッシュ）ｍｍ、、接着シート３としてエポキシ樹脂成分を含むシート、金属体４としてハイテンを用いて、せん断破断力実験ができるような金属－プリプレグ複合体Ａを製造した。一方、アルミニウムメッシュ２を用いずに同様の方法で同形状の金属－プリプレグ複合体Ｂを製造した。得られた金属－プリプレグ複合体Ａ及びＢを同条件で加熱プレスを実施し、得られた金属－繊維強化樹脂成形体のせん断破断力（引っ張り試験機を用いて実施。引っ張り速度１０ｍｍ／分）でせん断破断力を測定したところ、接合力は、おおよそ１．０５倍～１．３倍程度向上することがわかった。 [Confirmation of adhesive strength]
Carbon fiber-containing epoxy resin prepreg as prepreg 1, aluminum mesh (thickness 0.6, 10 mesh) mm as adhesion reinforcing layer 2, sheet containing epoxy resin component as adhesive sheet 3, and high tensile strength as metal body 4. , a metal-prepreg composite A was produced to enable shear rupture force experiments. On the other hand, without using the aluminum mesh 2, a metal-prepreg composite B having the same shape was produced in the same manner. The obtained metal-prepreg composites A and B were heat-pressed under the same conditions, and the obtained metal-fiber reinforced resin molded article had a shear breaking strength (measured using a tensile tester, tensile speed 10 mm / min). When the shear breaking strength was measured, it was found that the bonding strength was improved by about 1.05 to 1.3 times.
