Description
本発明は、金属板と炭素繊維強化樹脂シートとの一体成型部品製造方法および一体成型部品に関する。 The present invention relates to a method for producing an integrally molded part of a metal plate and a carbon fiber reinforced resin sheet, and an integral molded part.
従来、軽量化を目的として、自動車や飛行機などの骨格に、アルミニウム系金属が使用されている。アルミニウムを使用する場合、アルミニウムは通常使用されている鋼板に比べて剛性が弱く補強が必要である。このため、鋼板で補強することがある。しかし、アルミニウムを鋼板で補強した場合、アルミニウムと鋼板との接合面において、自然電位差が生じ、電気化学的腐蝕が発生する。 Conventionally, for the purpose of weight reduction, aluminum-based metals have been used in the skeletons of automobiles and airplanes. When aluminum is used, aluminum is less rigid than a normally used steel plate and needs to be reinforced. For this reason, it may reinforce with a steel plate. However, when aluminum is reinforced with a steel plate, a natural potential difference occurs at the joint surface between the aluminum and the steel plate, and electrochemical corrosion occurs.
このため、これを防止するために、特許文献１には、自然電位の低い材料からなるパッキンを介在させる技術が開示されている。 For this reason, in order to prevent this, Patent Document 1 discloses a technique in which a packing made of a material having a low natural potential is interposed.
近年、さらなる軽量化と剛性、強度の向上のため、炭素繊維強化樹脂などの強化樹脂の使用が検討されている。この強化樹脂は、車両や飛行機の骨格だけでなく、船、建材、橋などの補強部材としての使用も期待されている。 In recent years, the use of reinforced resins such as carbon fiber reinforced resins has been studied for further weight reduction, rigidity, and strength improvement. This reinforced resin is expected to be used not only as a frame for vehicles and airplanes but also as a reinforcing member for ships, building materials and bridges.
そこで、炭素繊維強化樹脂を金属板（鋼板やアルミニウム）で補強した一体成型部品を用いる場合、炭素繊維強化樹脂は、表面が樹脂であるため、アルミニウムのように、金属板との表面の接合面での電気化学的腐蝕は発生しないが、端部において、電気化学的腐蝕が発生する場合がある。これは、炭素繊維強化樹脂の端部が切断されたままであり、炭素繊維強化樹脂の端部から露出した炭素繊維に水分が付着することで、金属板との接触部位において自然電位に差が生じ、発生するためである。 Therefore, when using an integrally molded part in which carbon fiber reinforced resin is reinforced with a metal plate (steel plate or aluminum), the surface of the carbon fiber reinforced resin is a resin. In this case, electrochemical corrosion does not occur at the edge, but electrochemical corrosion may occur at the edge. This is because the end of the carbon fiber reinforced resin remains cut, and moisture adheres to the carbon fiber exposed from the end of the carbon fiber reinforced resin, resulting in a difference in natural potential at the contact point with the metal plate. This is because it occurs.
この端部での自然電位の差が金属板においてサビを発生させ、補強部材としての強度や剛性の特性を劣化させてしまう可能性がある。 This difference in natural potential at the end portion may cause rust in the metal plate and may deteriorate the strength and rigidity characteristics of the reinforcing member.
本発明は、上記課題に鑑みてなされたものであり、その目的の一例は、金属板と炭素繊維強化樹脂との一体成型部品において、金属板でのサビを防止できる一体成型部品製造方法および一体成型部品を提供することである。 The present invention has been made in view of the above problems, and an example of the object thereof is an integrally molded part manufacturing method and an integrated part capable of preventing rust on a metal plate in an integrally molded part of a metal plate and a carbon fiber reinforced resin.

さらに、上記解決手段に加えて、本発明に係る一体成型部品は、金属板と炭素繊維強化樹脂シートとの一体成型部品であって、炭素繊維強化樹脂シートの端部と金属板の表面とを離間して一体的に成形する。 Further, in addition to the above solution, the integrally molded component according to the present invention is an integrally molded component of a metal plate and a carbon fiber reinforced resin sheet, and includes an end portion of the carbon fiber reinforced resin sheet and a surface of the metal plate.

本発明の一体成型部品製造方法および一体成型部品によれば、自然電位の差により発生する金属板におけるサビを防止することで、補強部材としての強度や剛性の特性の劣化を防止できる。 According to the integrally molded component manufacturing method and the integrally molded component of the present invention, it is possible to prevent deterioration of strength and rigidity characteristics as a reinforcing member by preventing rust on the metal plate generated due to a difference in natural potential.
図１は、本発明の実施形態を示している。図１に基づいて本発明の一体成型部品について説明する。 FIG. 1 shows an embodiment of the present invention. The integrally molded part of the present invention will be described with reference to FIG.
図１は、本発明の実施形態に係る一体成型部品１の斜視図である。一体成型部品１は、鋼板やアルミニウム系金属などからなる金属板１０と炭素繊維強化樹脂シート２０とが重ね合されて一体となっている。炭素繊維強化樹脂シート２０の端部２０Ｔは、一体成型部品１において、金属板１０の表面１０Ｓから離間している。 FIG. 1 is a perspective view of an integrally molded component 1 according to an embodiment of the present invention. The integrally molded component 1 is formed by superimposing a metal plate 10 made of a steel plate or an aluminum-based metal and a carbon fiber reinforced resin sheet 20. The end 20T of the carbon fiber reinforced resin sheet 20 is separated from the surface 10S of the metal plate 10 in the integrally molded component 1.
金属板１０の表面１０Ｓが炭素繊維強化樹脂シート２０の端部２０Ｔから離間する方向は、炭素繊維強化樹脂シート２０の面２０Ｓに対して垂直方向となっている。なお、図１の右側は図示を省略しているが、左側と同様に金属板１０の表面が炭素繊維強化樹脂シート２０の端部２０Ｔから離間している。 The direction in which the surface 10 </ b> S of the metal plate 10 is separated from the end 20 </ b> T of the carbon fiber reinforced resin sheet 20 is perpendicular to the surface 20 </ b> S of the carbon fiber reinforced resin sheet 20. Although the illustration on the right side of FIG. 1 is omitted, the surface of the metal plate 10 is separated from the end 20T of the carbon fiber reinforced resin sheet 20 as in the left side.
このように、金属板１０を炭素繊維強化樹脂シート２０の端部２０Ｔから離間させているので、炭素繊維強化樹脂シート２０の端部２０Ｔから露出する炭素繊維に水分が付着したとしても、金属板１０との間に自然電位の差は生じず、金属板１０をサビから防ぐことができる。 As described above, since the metal plate 10 is separated from the end portion 20T of the carbon fiber reinforced resin sheet 20, even if moisture adheres to the carbon fiber exposed from the end portion 20T of the carbon fiber reinforced resin sheet 20, the metal plate No difference in natural potential occurs with respect to 10 and the metal plate 10 can be prevented from rust.
また、一体成型部品１を使用する場所によっては、金属板１０の表面に塗装が行われていてもよいが、塗装がない場合、炭素繊維強化樹脂シート２０の表面が溶解し金属板１０に接着しやすいので、金属板１０に塗装を行っていない本実施形態は接着においてより効果がある。 Moreover, depending on the place where the integrally molded component 1 is used, the surface of the metal plate 10 may be painted, but when there is no coating, the surface of the carbon fiber reinforced resin sheet 20 is dissolved and adhered to the metal plate 10. Therefore, the present embodiment in which the metal plate 10 is not coated is more effective in bonding.
図２は、本発明の実施形態にかかる一体成型部品１の断面図である。金属板１０と炭素繊維強化樹脂シート２０が張り合わされており、金属板１０が炭素繊維強化樹脂シート２０の端部２０Ｔから離間している。 FIG. 2 is a cross-sectional view of the integrally molded component 1 according to the embodiment of the present invention. The metal plate 10 and the carbon fiber reinforced resin sheet 20 are bonded together, and the metal plate 10 is separated from the end 20T of the carbon fiber reinforced resin sheet 20.
なお、図２の右側は図示を省略しているが、左側と同様に炭素繊維強化樹脂シート２０の端部２０Ｔが金属板１０から離間している。この離間する方向は、炭素繊維強化樹脂シート２０の面２０Ｓに対して垂直方向となっている。 In addition, although illustration is abbreviate | omitted on the right side of FIG. 2, the edge part 20T of the carbon fiber reinforced resin sheet 20 is spaced apart from the metal plate 10 similarly to the left side. The separating direction is a direction perpendicular to the surface 20 </ b> S of the carbon fiber reinforced resin sheet 20.
続いて、本実施形態に係る一体成型部品の製造方法を図３および図４に基いて説明する。 図３は、本発明の実施形態に係る一体成型部品製造方法を示すフローブロック図である。 図４は、本発明の実施形態に係る一体成型部品製造方法を示すフロー図である。 Then, the manufacturing method of the integrally molded component which concerns on this embodiment is demonstrated based on FIG. 3 and FIG. FIG. 3 is a flow block diagram showing an integrally molded part manufacturing method according to the embodiment of the present invention. FIG. 4 is a flowchart showing an integrally molded part manufacturing method according to the embodiment of the present invention.
一体成型部品製造方法を実現する装置は、下型ベース２００と上型第１パッド２０１と、離間部２０３を備えた上型第２パッド２０２から構成される。上型第１パッド２０１と、上型第２パッド２０２には、それぞれスプリングなどのプレスをするための部材が接続されている。 An apparatus for realizing the integrally molded component manufacturing method includes a lower mold base 200, an upper mold first pad 201, and an upper mold second pad 202 having a separation portion 203. Members for pressing such as a spring are connected to the upper mold first pad 201 and the upper mold second pad 202, respectively.
図３における重ね合わせ工程（ステップＳＴ１）は、図４のＡに、図３における第１プレス工程（ステップＳＴ２）は、図４のＢに、図３における第２プレス工程（ステップＳＴ３）は、図４のＣにそれぞれ対応する。 The overlay process (step ST1) in FIG. 3 is performed in FIG. 4A, the first press process (step ST2) in FIG. 3 is performed in FIG. 4B, and the second press process (step ST3) in FIG. Each corresponds to C in FIG.
まず、シート状の金属板１０と炭素繊維強化樹脂シート２０とを装置の下型ベース２００に載置し、重ね合わせる（ステップＳＴ１：図４のＡ）。このとき、炭素繊維強化樹脂シート２０は金属板１０よりも内側の位置で重ね合わされる。このため、炭素繊維強化樹脂シート２０の面積は金属板１０の面積よりも小さいことが好ましい。 First, the sheet-like metal plate 10 and the carbon fiber reinforced resin sheet 20 are placed on the lower mold base 200 of the apparatus and overlapped (step ST1: A in FIG. 4). At this time, the carbon fiber reinforced resin sheet 20 is overlapped at a position inside the metal plate 10. For this reason, the area of the carbon fiber reinforced resin sheet 20 is preferably smaller than the area of the metal plate 10.
下型ベース２００は凹部を備えており、その深さ２００Ｈは炭素繊維強化樹脂シート２０の重ね位置に影響する。また、上型第２パッド２０２の離間部２０３の高さ２０３Ｈも炭素繊維強化樹脂シート２０の重ね位置に影響する。 The lower mold base 200 has a recess, and the depth 200H affects the overlapping position of the carbon fiber reinforced resin sheet 20. Further, the height 203H of the separation portion 203 of the upper second pad 202 also affects the overlapping position of the carbon fiber reinforced resin sheet 20.
炭素繊維強化樹脂シート２０は、下型ベース２００に載置された金属板１０に対して、
下型ベース２００の角部２００Ｋから平坦部２００Ｔ側に、下型ベース２００の深さ２００Ｈと上型第２パッド２０２の離間部２０３の高さ２０３Ｈを足し合わせた長さ分の位置が端部となるように、金属板１０と重ね合わせられる。
The carbon fiber reinforced resin sheet 20 is in contrast to the metal plate 10 placed on the lower mold base 200.
The position corresponding to the length obtained by adding the depth 200H of the lower mold base 200 and the height 203H of the separation part 203 of the upper mold second pad 202 from the corner part 200K of the lower mold base 200 to the flat part 200T side is the end part. The metal plate 10 is overlaid so that
次に、第１プレス工程によって、上型第１パッド２０１が、下型ベース２００の凹部に対して、金属板１０と炭素繊維強化樹脂シート２０とが重なった部分をプレスする（ステップＳＴ２：図４のＢ）。 Next, in the first pressing step, the upper mold first pad 201 presses the portion where the metal plate 10 and the carbon fiber reinforced resin sheet 20 overlap each other with respect to the concave portion of the lower mold base 200 (step ST2: FIG. 4 B).
金属板１０と炭素繊維強化樹脂シート２０とが重なった部分が上型第１パッド２０１によってプレスされると、金属板１０と炭素繊維強化樹脂シート２０は上型第１パッド２０１のプレスに応じて、上型第１パッド２０１の側面２０１Lと下型ベース２００の側面２００Rとの間隙を通るように図４の上側へ曲がる。 When the portion where the metal plate 10 and the carbon fiber reinforced resin sheet 20 overlap is pressed by the upper mold first pad 201, the metal plate 10 and the carbon fiber reinforced resin sheet 20 correspond to the pressing of the upper mold first pad 201. 4 is bent upward so as to pass through the gap between the side surface 201L of the upper mold first pad 201 and the side surface 200R of the lower mold base 200.
金属板１０の一部１０Ｖと、炭素繊維強化樹脂シート２０の一部２０Ｖは、重なったまま上側へ曲がっている。金属板１０は、さらに、上型第２パッド２０２に接し、金属板１０の一部１０Ｒのように曲がる。 Part 10V of the metal plate 10 and part 20V of the carbon fiber reinforced resin sheet 20 are bent upward while overlapping. Furthermore, the metal plate 10 contacts the upper mold second pad 202 and bends like a part 10 </ b> R of the metal plate 10.
炭素繊維強化樹脂シート２０の一部２０Ｖは、予め、下型ベース２００の深さ２００Ｈと上型第２パッド２０２の離間部２０３の高さ２０３Ｈを考慮して配置されているので、上型第２パッド２０２には接せず、図４において上側へほぼまっすぐに曲がっている。 The part 20V of the carbon fiber reinforced resin sheet 20 is disposed in advance in consideration of the depth 200H of the lower mold base 200 and the height 203H of the separation portion 203 of the upper mold second pad 202. 2 does not contact the pad 202 and is bent almost straight upward in FIG.
次に、第２プレス工程によって、上型第１パッド２０１がプレス状態のまま、上型第２パッド２０２が、金属板１０をプレスする（ステップＳＴ３：図４のＣ）。 Next, in the second pressing step, the upper die second pad 202 presses the metal plate 10 while the upper die first pad 201 remains in the pressed state (step ST3: C in FIG. 4).
上型第２パッド２０２は、ステップＳＴ２で曲がった金属板１０の一部１０Ｒを下型ベース２００の平坦部２００Ｔに接するように曲げていくとともに、離間部２０３によって、金属板１０と、炭素繊維強化樹脂シート２０の端部２０Ｔとを確実に離すようにプレスする。なお、プレス時には、必要に応じて、適宜パッドやベースを加熱することで、加工しやすくすることも可能である。 The upper die second pad 202 bends a portion 10R of the metal plate 10 bent in step ST2 so as to contact the flat portion 200T of the lower die base 200, and the metal plate 10 and the carbon fiber are separated by the separation portion 203. It presses so that the edge part 20T of the reinforced resin sheet 20 may leave | separate reliably. In addition, at the time of pressing, it is possible to facilitate processing by appropriately heating the pad and base as necessary.
例えば、加熱により重合を起こして高分子の網目構造を形成し、硬化する熱硬化性樹脂を使用した場合、金属板１０と炭素繊維強化樹脂シート２０の重ね合わせを行い、プレス後の一体成型部品１を加熱する。この加熱は、プレス時のパッドを加熱することで行うことも可能である。 For example, when a thermosetting resin that polymerizes by heating to form a polymer network structure and is cured is used, the metal plate 10 and the carbon fiber reinforced resin sheet 20 are overlapped, and the integrally molded part after pressing 1 is heated. This heating can also be performed by heating the pad during pressing.
また、ガラス転移温度または融点まで加熱することによって軟らかくなる熱可塑性樹脂を使用した場合、金属板１０と炭素繊維強化樹脂シート２０の重ね合わせを行った後のプレス時に、加熱された上型パッド２０１，２０２によって炭素繊維強化樹脂シート２０側からプレスをするようにする。若しくは、下型ベース２００を加熱しておき、金属板１０を介して炭素繊維強化樹脂シート２０を加熱するようにしてもよい。 When a thermoplastic resin that becomes soft by heating to the glass transition temperature or melting point is used, the heated upper pad 201 is heated during pressing after the metal plate 10 and the carbon fiber reinforced resin sheet 20 are superposed. , 202 is pressed from the carbon fiber reinforced resin sheet 20 side. Alternatively, the lower mold base 200 may be heated and the carbon fiber reinforced resin sheet 20 may be heated via the metal plate 10.
以上のような工程によって、本実施形態の一体成型部品１が製造される。 The integrally molded component 1 of the present embodiment is manufactured through the above-described steps.
一体成型部品１は、プレス後、不要な金属板１０の一部を切断したり、またさらなる形状加工を経て使用することも可能である。 The integrally molded component 1 can be used after being pressed, by cutting a part of an unnecessary metal plate 10 or through further shape processing.
例えば、車両のボディーや骨格、飛行機や船のボディーや骨格、建材、橋などの補強部材として使用できる。 For example, it can be used as a reinforcing member for vehicle bodies and skeletons, airplane and ship bodies and skeletons, building materials, bridges, and the like.
