Description

複合材成形装置および複合材成形方法Composite molding equipment and composite molding method
　本発明は、複合材成形装置および複合材成形方法に関するものである。 The present invention relates to a composite material molding apparatus and a composite material molding method.
　従来、航空機の胴体に代表されるような、円筒形の複合材構造部品の製造方法が知られている（例えば、特許文献１および特許文献２参照）。特許文献１には、円柱状に形成されたマンドレルに樹脂を含侵させた繊維束を巻き付け、樹脂の硬化後にマンドレルを繊維束から抜き取って複合材を成形する装置が開示されている。特許文献２には、熱可塑性樹脂により繊維基材同士が接合された繊維基材積層体を賦形型に設置してラバーシートで覆い、真空ポンプにより内部を減圧して繊維基材積層体を賦形する装置が開示されている。 Conventionally, a method for manufacturing a cylindrical composite structural part typified by an aircraft fuselage is known (see, for example, Patent Document 1 and Patent Document 2). Patent Document 1 discloses an apparatus in which a fiber bundle impregnated with a resin is wound around a mandrel formed in a columnar shape, and after the resin is cured, the mandrel is extracted from the fiber bundle to form a composite material. In Patent Document 2, a fiber base material laminate in which fiber base materials are bonded to each other by a thermoplastic resin is installed in a shaped mold, covered with a rubber sheet, and the inside is depressurized by a vacuum pump to form the fiber base material laminate. The shaping device is disclosed.
特開平１０－９５５７０号公報Japanese Unexamined Patent Publication No. 10-95570 特開２００８－２３００１９号公報Japanese Unexamined Patent Publication No. 2008-230019
　特許文献１では、繊維束を送り出す装置に揺動部が設けられており、揺動部を回動させることによりマンドレルに対して繊維束を任意の方向に巻き付けることができる。しかしながら、繊維束を複数の方向に巻き付けて積層する際には、マンドレルを回転させながらある方向に繊維束を巻き付けた後に揺動部の回動角度を変更し、再びマンドレルを回転させながら異なる方向に繊維束を巻き付ける必要がある。そのため、繊維束を複数の方向に巻き付けて積層するのに多くの時間を要してしまう。また、繊維束を積層した後に繊維束に含まれる樹脂を硬化させる処理が必要であるため、製造時間が増加してしまう。 In Patent Document 1, a swinging portion is provided in the device for feeding the fiber bundle, and the fiber bundle can be wound around the mandrel in an arbitrary direction by rotating the swinging portion. However, when the fiber bundles are wound in a plurality of directions and laminated, the rotation angle of the swing portion is changed after the fiber bundles are wound in a certain direction while rotating the mandrel, and the mandrel is rotated again in different directions. It is necessary to wrap the fiber bundle around. Therefore, it takes a lot of time to wind the fiber bundles in a plurality of directions and stack them. In addition, since it is necessary to perform a process of curing the resin contained in the fiber bundle after laminating the fiber bundle, the production time increases.
　特許文献２では、平板上に予め積層された強化繊維基材積層体を賦形型の形状に沿って賦形するため、賦形する際に繊維基材の層間で滑りが発生し、リンクル（皺）などの成形不良が発生する可能性がある。 In Patent Document 2, since the reinforcing fiber base material laminate laminated in advance on the flat plate is shaped according to the shape of the shaping mold, slippage occurs between the layers of the fiber base material during shaping, and the wrinkle ( Molding defects such as wrinkles) may occur.
　本発明は、このような事情に鑑みてなされたものであって、複数の繊維方向に配向された繊維基材が積層された曲面形状を有する複合材を成形する際に、製造時間を短縮しつつ成形品質を向上させることが可能な複合材成形装置および複合材成形方法を提供することを目的とする。 The present invention has been made in view of such circumstances, and shortens the manufacturing time when molding a composite material having a curved surface shape in which fiber base materials oriented in a plurality of fiber directions are laminated. It is an object of the present invention to provide a composite material molding apparatus and a composite material molding method capable of improving molding quality.
　上記課題を解決するために、本発明の複合材成形装置および複合材成形方法は、以下の手段を採用する。
　本発明の一態様に係る複合材成形装置は、軸線に沿って延びる回転体と、前記回転体を前記軸線回りに回転させる駆動力を発生する駆動部と、所定の繊維方向に配向された繊維基材を含むシート状の複合材料が巻き付けられたロールを回転させて前記複合材料を前記回転体に向けて供給する複数の供給部と、複数の前記供給部の各々に対応して設けられ、前記供給部により供給される前記複合材料を加熱する複数の加熱部と、複数の前記供給部の各々に対応して設けられ、前記加熱部により加熱された前記複合材料を前記回転体に巻き付けながら加圧する複数の加圧部と、を備え、複数の前記供給部に含まれるいずれかの前記供給部が供給する前記繊維基材の前記所定の繊維方向は、複数の前記供給部に含まれる他の前記供給部が供給する前記繊維基材の前記所定の繊維方向と異なる。 In order to solve the above problems, the composite material molding apparatus and the composite material molding method of the present invention employ the following means.
The composite material forming apparatus according to one aspect of the present invention includes a rotating body extending along an axis, a driving unit that generates a driving force for rotating the rotating body around the axis, and fibers oriented in a predetermined fiber direction.

　第１ロール成形機構１０，第２ロール成形機構２０，第３ロール成形機構３０，第４ロール成形機構４０は、それぞれシート状のロール材をマンドレル１に巻き付ける点で同様の機能を備えている。第１ロール成形機構１０，第２ロール成形機構２０，第３ロール成形機構３０，第４ロール成形機構４０は、それぞれが供給するロール材の種類において異なっている。具体的には、第１ロール材Ｒ１と第２ロール材Ｒ２と第３ロール材Ｒ３と第４ロール材Ｒ４は、それぞれ一方向にのみ繊維を配向するロール材であり、ロール材を供給する供給方向に対する繊維方向がそれぞれ異なっている。 The first roll forming mechanism 10, the second roll forming mechanism 20, the third roll forming mechanism 30, and the fourth roll forming mechanism 40 each have the same function in that a sheet-shaped roll material is wound around the mandrel 1. The first roll forming mechanism 10, the second roll forming mechanism 20, the third roll forming mechanism 30, and the fourth roll forming mechanism 40 are different in the type of roll material supplied by each. Specifically, the first roll material R1, the second roll material R2, the third roll material R3, and the fourth roll material R4 are roll materials that orient fibers in only one direction, respectively, and supply the roll material. The fiber direction with respect to the direction is different.

The direction of the solid line of the first roll material R1 shown in FIG. 3A is the fiber direction, which is a direction inclined by 45 degrees counterclockwise with respect to the supply direction. Since the fiber direction is deviated by 45 degrees in the negative direction with respect to the second roll material R2 which is a 0 ° angle layer roll described later, the first roll material R1 is called a −45 ° angle layer roll.
　図３Ｂは、第２ロール成形機構２０が供給する第２ロール材Ｒ２の供給方向と繊維方向を示す平面図である。図３Ｂに示す第２ロール材Ｒ２の実線の方向が繊維方向であり供給方向に対して９０度傾斜した方向となっている。第１ロール材Ｒ１を０°角度層ロールという。 FIG. 3B is a plan view showing the supply direction and the fiber direction of the second roll material R2 supplied by the second roll forming mechanism 20.

The first roll material R1 is called a 0 ° angle layer roll.
　図３Ｃは、第３ロール成形機構３０が供給する第３ロール材Ｒ３の供給方向と繊維方向を示す平面図である。図３Ｃに示す第３ロール材Ｒ３の実線の方向が繊維方向であり供給方向に対して時計回りに４５度傾斜した方向となっている。０°角度層ロールである第２ロール材Ｒ２に対して正の方向に４５度繊維方向がずれているため、第３ロール材Ｒ３を４５°角度層ロールという。 FIG. 3C is a plan view showing the supply direction and the fiber direction of the third roll material R3 supplied by the third roll forming mechanism 30. The direction of the solid line of the third roll material R3 shown in FIG. 3C is the fiber direction, which is a direction inclined by 45 degrees clockwise with respect to the supply direction. Since the fiber direction is deviated by 45 degrees in the positive direction with respect to the second roll material R2 which is a 0 ° angle layer roll, the third roll material R3 is called a 45 ° angle layer roll.
　図３Ｄは、第４ロール成形機構４０が供給する第４ロール材Ｒ４の供給方向と繊維方向を示す平面図である。図３Ｄに示す第４ロール材Ｒ４の実線の方向が繊維方向であり供給方向と平行な方向となっている。０°角度層ロールである第２ロール材Ｒ２に対して正の方向に９０度繊維方向がずれているため、第４ロール材Ｒ４を９０°角度層ロールという。 FIG. 3D is a plan view showing the supply direction and the fiber direction of the fourth roll material R4 supplied by the fourth roll forming mechanism 40. The direction of the solid line of the fourth roll material R4 shown in FIG. 3D is the fiber direction and is parallel to the supply direction. Since the fiber direction is deviated by 90 degrees in the positive direction with respect to the second roll material R2 which is a 0 ° angle layer roll, the fourth roll material R4 is called a 90 ° angle layer roll.
　このように、第１ロール成形機構１０，第２ロール成形機構２０，第３ロール成形機構３０，第４ロール成形機構４０は、ロール材を供給する供給方向に対する繊維方向が異なっている。これらの４つのロール成形機構から繊維方向の異なる４種類のロール材をマンドレル１に積層することで、所望の強度を持った複合材を成形することができる。 As described above, the first roll forming mechanism 10, the second roll forming mechanism 20, the third roll forming mechanism 30, and the fourth roll forming mechanism 40 have different fiber directions with respect to the supply direction in which the roll material is supplied. By laminating four types of roll materials having different fiber directions on the mandrel 1 from these four roll forming mechanisms, a composite material having a desired strength can be formed.

Although the fourth roll material R4 is assumed to be a 90 ° angle layer roll, other embodiments may be used. For example, if these four types of angle layer rolls are used for the first roll material R1, the second roll material R2, the third roll material R3, and the fourth roll material R4, any combination may be used. Further, in the first roll material R1, the second roll material R2, the third roll material R3, and the fourth roll material R4, three or two types of angle layer rolls may be used. In this case, at least two roll materials are the same type of angle layer roll.
　第１ロール成形機構１０は、第１ロール材Ｒ１をマンドレル１へ向けて供給しながら加熱し、加熱した第１ロール材Ｒ１を加圧しながらマンドレル１に巻き付ける機構である。第１ロール成形機構１０は、第１供給部１１と、第１ヒータ（第１加熱部）１２と、第１加圧ローラ（第１加圧部）１３と、第１冷却ローラ（第１冷却部）１４と、第１カッター（第１切断部）１５と、を備える。 The first roll forming mechanism 10 is a mechanism that heats the first roll material R1 while supplying it toward the mandrel 1 and winds the heated first roll material R1 around the mandrel 1 while applying pressure. The first roll forming mechanism 10 includes a first supply unit 11, a first heater (first heating unit) 12, a first pressurizing roller (first pressurizing unit) 13, and a first cooling roller (first cooling unit). A portion) 14 and a first cutter (first cutting portion) 15 are provided.
　第１供給部１１は、シート状の第１ロール材Ｒ１が巻き付けられた第１ロール１１ａを軸線Ｘｒ１回りに回転させて第１ロール材Ｒ１をマンドレル１に向けて供給する装置である。軸線Ｘｒ１は、マンドレル１の中心軸である軸線Ｘｍと平行に延びる軸線である。第１供給部１１は、軸線Ｘｍに沿った軸線方向に直交する方向に沿って第１ロール材Ｒ１をマンドレル１に向けて供給する。第１供給部１１は、第１ロール１１ａを軸線Ｘｒ１回りに回転させる駆動力を発生する駆動部（図示略）を備える。駆動部は、例えば、電動モータである。 The first supply unit 11 is a device for supplying the first roll material R1 toward the mandrel 1 by rotating the first roll 11a around which the sheet-shaped first roll material R1 is wound around the axis Xr1. The axis Xr1 is an axis extending parallel to the axis Xm, which is the central axis of the mandrel 1. The first supply unit 11 supplies the first roll material R1 toward the mandrel 1 along a direction orthogonal to the axial direction along the axis Xm. The first supply unit 11 includes a drive unit (not shown) that generates a driving force that rotates the first roll 11a around the axis Xr1. The drive unit is, for example, an electric motor.
　第１ヒータ１２は、第１供給部１１により供給される第１ロール材Ｒ１に含まれる熱可塑性樹脂を融点以上に加熱する装置である。図１に示すように、第１ヒータ１２は、第１ロール材Ｒ１の両面をそれぞれ加熱する一対の加熱源を有する。第１ヒータ１２により加熱された第１ロール材Ｒ１は、第１加圧ローラ１３へ向けて送り出される。なお、第１ヒータ１２は、第１ロール材Ｒ１のいずれか一方の面のみを加熱する単一の加熱源を有するものでもよい。 The first heater 12 is a device that heats the thermoplastic resin contained in the first roll material R1 supplied by the first supply unit 11 to a melting point or higher. As shown in FIG. 1, the first heater 12 has a pair of heating sources for heating both surfaces of the first roll material R1. The first roll material R1 heated by the first heater 12 is sent out toward the first pressurizing roller 13. The first heater 12 may have a single heating source that heats only one surface of the first roll material R1.
　第１加圧ローラ１３は、第１ヒータ１２により加熱された第１ロール材Ｒ１をマンドレル１に巻き付けながら加圧する装置である。第１加圧ローラ１３は、軸線Ｘｍと平行に延びる円柱状に形成されており、軸線Ｘｍに沿った各位置において第１ロール材Ｒ１を加圧しながらマンドレル１に巻き付ける。 The first pressurizing roller 13 is a device that pressurizes the first roll material R1 heated by the first heater 12 while winding it around the mandrel 1. The first pressurizing roller 13 is formed in a columnar shape extending parallel to the axis Xm, and is wound around the mandrel 1 while pressurizing the first roll material R1 at each position along the axis Xm.
　第１加圧ローラ１３は、第１ロール材Ｒ１を加圧しながらマンドレル１に巻き付けるため、すでに他のロール材がマンドレル１に積層されている場合にはそのロール材との間に空気等が存在しないようにすることができる。第１加圧ローラ１３は、弾性と耐熱性を有する材料（例えば、シリコーンゴム）により形成するのが好ましい。弾性を有する材料とすることで、第１ロール材Ｒ１を広範囲に加圧するための接触面積を確保することができる。耐熱性を有する材料とすることで、加熱された第１ロール材の温度に対する耐久性を確保できる。 Since the first pressurizing roller 13 winds the first roll material R1 around the mandrel 1 while pressurizing it, if another roll material is already laminated on the mandrel 1, air or the like exists between the roll material and the roll material. You can avoid it. The first pressure roller 13 is preferably formed of a material having elasticity and heat resistance (for example, silicone rubber). By using an elastic material, it is possible to secure a contact area for pressurizing the first roll material R1 over a wide range. By using a material having heat resistance, durability against the temperature of the heated first roll material can be ensured.
　第１冷却ローラ１４は、第１加圧ローラ１３によりマンドレル１に巻き付けられた第１ロール材Ｒ１に含まれる熱可塑性樹脂を融点未満に冷却する装置である。第１冷却ローラ１４は、軸線Ｘｍと平行に延びる円柱状に形成されており、軸線Ｘｍに沿った各位置において第１ロール材Ｒ１と接触しながら回転して第１ロール材Ｒ１を冷却する。 The first cooling roller 14 is a device that cools the thermoplastic resin contained in the first roll material R1 wound around the mandrel 1 by the first pressure roller 13 to below the melting point. The first cooling roller 14 is formed in a columnar shape extending parallel to the axis Xm, and rotates while contacting the first roll material R1 at each position along the axis Xm to cool the first roll material R1.
　第１冷却ローラ１４の内部には、冷却水を流通させる冷却水配管（図示略）が形成されている。外部から冷却水配管に冷却水が供給され、冷却水配管から外部へ冷却水が排出されるようになっている。そのため、マンドレル１に巻き付けられた第１ロール材Ｒ１は、冷却水配管を流通する冷却水によって冷却される。 A cooling water pipe (not shown) for circulating cooling water is formed inside the first cooling roller 14. Cooling water is supplied to the cooling water pipe from the outside, and the cooling water is discharged from the cooling water pipe to the outside. Therefore, the first roll material R1 wound around the mandrel 1 is cooled by the cooling water flowing through the cooling water pipe.
　なお、第１冷却ローラ１４は、熱可塑性樹脂を融点未満に冷却するのが望ましいが、融点近傍の所定の温度まで冷却するものであってもよい。熱可塑性樹脂が融点未満に冷却されない場合でも、融点近傍の所定の温度まで冷却することにより、さらなる時間経過や他の部材との接触による放熱により第１ロール材Ｒ１を融点未満の温度とすることができる。 Although it is desirable that the first cooling roller 14 cools the thermoplastic resin below the melting point, it may be cooled to a predetermined temperature near the melting point. Even when the thermoplastic resin is not cooled below the melting point, by cooling it to a predetermined temperature near the melting point, the temperature of the first roll material R1 is set to a temperature below the melting point by further lapse of time or heat dissipation due to contact with other members. Can be done.

FIG. 4 is a flowchart showing a composite material molding method according to the present embodiment. The process shown in FIG. 4 is executed by the control device 90 shown in FIG.

　図４に示す処理は、第１ロール成形機構１０と、第２ロール成形機構２０と、第３ロール成形機構３０と、第４ロール成形機構４０のそれぞれに対して制御装置９０がそれぞれ独立に実行する処理である。制御装置９０は、例えば、図４に示す処理を、第１ロール成形機構１０に対して実行すると同時に、第２ロール成形機構２０に対して実行する。 The processing shown in FIG. 4 is executed independently by the control device 90 for each of the first roll forming mechanism 10, the second roll forming mechanism 20, the third roll forming mechanism 30, and the fourth roll forming mechanism 40. It is a process to do. For example, the control device 90 executes the process shown in FIG. 4 on the first roll forming mechanism 10 and at the same time on the second roll forming mechanism 20.
　これにより、第１ロール材Ｒ１，第２ロール材Ｒ２，第３ロール材Ｒ３，第４ロール材Ｒ４のそれぞれを、任意のタイミングかつ任意の長さでマンドレル１に巻き付けることができる。制御装置９０には、最終的に成形する複合材と一致するように、どのようなタイミングでどのロール材をマンドレル１に巻き付けるかの設定情報が予め記憶されている。制御装置９０は、予め記憶された設定情報に基づいて第１ロール成形機構１０と、第２ロール成形機構２０と、第３ロール成形機構３０と、第４ロール成形機構４０のそれぞれに対して制御指示を送信する。 As a result, each of the first roll material R1, the second roll material R2, the third roll material R3, and the fourth roll material R4 can be wound around the mandrel 1 at an arbitrary timing and at an arbitrary length.

The control device 90 controls each of the first roll forming mechanism 10, the second roll forming mechanism 20, the third roll forming mechanism 30, and the fourth roll forming mechanism 40 based on the setting information stored in advance. Send instructions.
　以下、図４に示す各処理について説明する。以下では、制御装置９０が第１ロール成形機構１０に対して実行する処理を説明する。第２ロール成形機構２０，第３ロール成形機構３０，第４ロール成形機構４０に対して制御装置９０が実行する処理は、第１ロール成形機構１０に対する処理と同様であるため、以下での説明を省略する。 Hereinafter, each process shown in FIG. 4 will be described. Hereinafter, the process executed by the control device 90 with respect to the first roll forming mechanism 10 will be described. The processing executed by the control device 90 for the second roll forming mechanism 20, the third roll forming mechanism 30, and the fourth roll forming mechanism 40 is the same as the processing for the first roll forming mechanism 10, and thus will be described below. Is omitted.
　図４に示す各処理を実行している際に、制御装置９０は、モータ２にマンドレル１を回転させる駆動力を発生させる指示を伝達しているものとする。すなわち、図４に示す各処理を実行している際に、マンドレル１は図１に示す回転方向に回転しているものとする。 It is assumed that the control device 90 transmits an instruction to the motor 2 to generate a driving force for rotating the mandrel 1 while executing each process shown in FIG.

　ステップＳ１０１において、第１ロール材Ｒ１を供給するか否かが判断され、ＹＥＳであればステップＳ１０２へ進みＮＯであればステップＳ１０６へ処理を進める。
　ステップＳ１０２（供給工程）において、第１ロール材Ｒ１を供給するように第１供給部１１が制御される。第１供給部１１は、第１ロール材Ｒ１が巻き付けられた第１ロール１１ａを回転させて第１ロール材Ｒ１をマンドレル１に向けて供給する。 In step S101, it is determined whether or not to supply the first roll material R1, and if YES, the process proceeds to step S102, and if NO, the process proceeds to step S106.
In step S102 (supply step), the first supply unit 11 is controlled so as to supply the first roll material R1. The first supply unit 11 rotates the first roll 11a around which the first roll material R1 is wound to supply the first roll material R1 toward the mandrel 1.
　ステップＳ１０３（加熱工程）において、ステップＳ１０２により供給される第１ロール材Ｒ１に含まれる熱可塑性樹脂が第１ヒータ１２により融点以上に加熱される。

When the control device 90 determines NO in step S101, the control device 90 executes the process of step S106.
　ステップＳ１０６において、第１ロール材Ｒ１をマンドレル１に供給し、加熱し、加圧し、冷却する一連の処理を停止する停止処理が実行される。制御装置９０は、第１ロール１１ａの回転を停止させるよう第１供給部１１を制御し、第１ロール材Ｒ１の加熱を停止するよう第１ヒータ１２を制御する。また、制御装置９０は、第１ロール材Ｒ１を切断するよう第１カッター１５を制御する。 In step S106, a stop process of supplying the first roll material R1 to the mandrel 1, heating, pressurizing, and cooling is executed. The control device 90 controls the first supply unit 11 so as to stop the rotation of the first roll 11a, and controls the first heater 12 so as to stop the heating of the first roll material R1. Further, the control device 90 controls the first cutter 15 so as to cut the first roll material R1.
　以上説明した本実施形態の複合材成形装置１００が奏する作用および効果について説明する。
　本実施形態の複合材成形装置１００によれば、第１供給部１１がマンドレル１に供給する第１ロール材Ｒ１は、第１ヒータ１２により熱可塑性樹脂が融点以上に加熱され、第１加圧ローラ１３によりマンドレル１に巻き付けられながら加圧される。また、第２供給部２１がマンドレル１に供給するシート状の第２ロール材Ｒ２は、第２ヒータ２２により熱可塑性樹脂が融点以上に加熱され、第２加圧ローラ２３によりマンドレル１に巻き付けられながら加圧される。第１ロール材Ｒ１および第２ロール材Ｒ２は、加圧されることによって下層に配置される他のロール材と強固に結合され、その後冷却されることによって緻密化する。第３ロール材Ｒ３および第４ロール材Ｒ４についても同様である。 The action and effect of the composite material molding apparatus 100 of the present embodiment described above will be described.
According to the composite material molding apparatus 100 of the present embodiment, in the first roll material R1 supplied by the first supply unit 11 to the mandrel 1, the thermoplastic resin is heated to the melting point or higher by the first heater 12, and the first pressurization is performed. It is pressurized while being wound around the mandrel 1 by the roller 13. Further, in the sheet-shaped second roll material R2 supplied by the second supply unit 21 to the mandrel 1, the thermoplastic resin is heated to the melting point or higher by the second heater 22, and is wound around the mandrel 1 by the second pressure roller 23. While being pressurized. The first roll material R1 and the second roll material R2 are firmly bonded to other roll materials arranged in the lower layer by being pressed, and then densified by being cooled. The same applies to the third roll material R3 and the fourth roll material R4.
　本実施形態の複合材成形装置１００によれば、第１ロール材Ｒ１に含まれる第１繊維基材の第１繊維方向（－４５°）と第２ロール材Ｒ２に含まれる第２繊維基材の第２繊維方向（０°）とが異なるため、第１供給部１１からの第１ロール材Ｒ１の供給と第２供給部２１からの第２ロール材Ｒ２の供給とを同時に行うことで、複数の繊維方向に配向された繊維基材が積層された複合材の製造時間を短縮することができる。また、第１ロール材Ｒ１および第２ロール材Ｒ２が円筒状のマンドレル１の形状に沿って積層されるため、繊維基材の層間で滑りによるリンクル（皺）の発生等の成形不良が発生せず、成形品質が向上する。 According to the composite material forming apparatus 100 of the present embodiment, the first fiber direction (−45 °) of the first fiber base material contained in the first roll material R1 and the second fiber base material contained in the second roll material R2. Since the direction of the second fiber (0 °) is different from that of the above, the supply of the first roll material R1 from the first supply unit 11 and the supply of the second roll material R2 from the second supply unit 21 can be performed at the same time. It is possible to shorten the production time of a composite material in which a fiber base material oriented in a plurality of fiber directions is laminated. Further, since the first roll material R1 and the second roll material R2 are laminated along the shape of the cylindrical mandrel 1, molding defects such as wrinkles due to slippage occur between the layers of the fiber base material. However, the molding quality is improved.
　また、本実施形態の複合材成形装置１００によれば、第１ロール材Ｒ１および第２ロール材Ｒ２がそれぞれ軸線Ｘｍ方向に直交する方向に沿ってマンドレル１に供給されるとともに、これらが巻き付けられる軸線Ｘｍ方向の領域が一致している。そのため、第１供給部１１からの第１ロール材Ｒ１の供給と第２供給部２１からの第２ロール材Ｒ２の供給とを同時に行うことで、マンドレル１に第１ロール材Ｒ１および第２ロール材Ｒ２をマンドレル１に巻き付けながら積層させることができる。 Further, according to the composite material forming apparatus 100 of the present embodiment, the first roll material R1 and the second roll material R2 are supplied to the mandrel 1 along the directions orthogonal to the axis Xm direction, and these are wound around the mandrel 1. The regions in the Xm direction of the axis line match.

〔他の実施形態〕
　以上の説明において、マンドレル１は軸線Ｘｍを中心として軸線Ｘｍに沿って延びる円筒状の外周面１ａを有するものとしたが、他の態様であってもよい。例えば、図７の変形例に示すように、外周面１ａの周方向の複数個所に軸線Ｘｍに沿って延びる凹所１ｂを設けるようにしてもよい。図７は、変形例に係る複合材成形装置１００Ｂを示す断面図である。 [Other Embodiments]
In the above description, the mandrel 1 has a cylindrical outer peripheral surface 1a extending along the axis Xm about the axis Xm, but other embodiments may be used. For example, as shown in the modified example of FIG. 7, recesses 1b extending along the axis Xm may be provided at a plurality of locations in the circumferential direction of the outer peripheral surface 1a. FIG. 7 is a cross-sectional view showing a composite material molding apparatus 100B according to a modified example.
　変形例に係る複合材成形装置１００Ｂが備えるマンドレル１は、外周面１ａに軸線Ｘｍに沿って延びる凹所１ｂが設けられている。凹所１ｂには、凹所１ｂと同形状の外周面５ａを有するとともに軸線Ｘｍに沿って延びるストリンガ５が配置されている。ストリンガ５の原材料は、第１ロール材Ｒ１，第２ロール材Ｒ２，第３ロール材Ｒ３，第４ロール材Ｒ４と同様に、繊維基材に熱可塑性のマトリックス樹脂が付着された複合材料である。ストリンガ５は、凹所１ｂの形状と一致するように予め加圧および加熱により賦形された複合材である。 The mandrel 1 included in the composite material forming apparatus 100B according to the modified example is provided with a recess 1b extending along the axis Xm on the outer peripheral surface 1a. In the recess 1b, a stringer 5 having an outer peripheral surface 5a having the same shape as the recess 1b and extending along the axis Xm is arranged. The raw material of the stringer 5 is a composite material in which a thermoplastic matrix resin is attached to a fiber base material, similarly to the first roll material R1, the second roll material R2, the third roll material R3, and the fourth roll material R4. .. The stringer 5 is a composite material previously shaped by pressurization and heating to match the shape of the recess 1b.
　ストリンガ５とマンドレル１に積層されるロール材との間の空間には、軸線Ｘｍに沿って延びる成形用治具６が配置されている。この空間は、マンドレル１の凹所１ｂにストリンガ５を配置した場合に、マンドレル１の外周面１ａよりも軸線Ｘｍに向けて凹んだ空間である。成形用治具６の外周面６ａは、凹所１ｂに配置された状態でマンドレル１の外周面１ａと一致する位置に配置される形状となっている。成形用治具６は、第１加圧ローラ１３，第２加圧ローラ２３，第３加圧ローラ３３，第４加圧ローラ４３によりロール材を加圧する際に、ロール材がストリンガ５側に変形しないように支持するものである。成形用治具６は、マンドレル１へのロール材の積層が完了してマンドレル１から完成した複合材を取り外す際に除去される。 In the space between the stringer 5 and the roll material laminated on the mandrel 1, a molding jig 6 extending along the axis Xm is arranged. This space is a space recessed toward the axis Xm from the outer peripheral surface 1a of the mandrel 1 when the stringer 5 is arranged in the recess 1b of the mandrel 1. The outer peripheral surface 6a of the molding jig 6 has a shape of being arranged at a position corresponding to the outer peripheral surface 1a of the mandrel 1 in a state of being arranged in the recess 1b. In the molding jig 6, when the roll material is pressed by the first pressure roller 13, the second pressure roller 23, the third pressure roller 33, and the fourth pressure roller 43, the roll material is moved to the stringer 5 side. It supports it so that it does not deform. The molding jig 6 is removed when the stacking of the roll material on the mandrel 1 is completed and the completed composite material is removed from the mandrel 1.
　本変形例によれば、ストリンガ５にロール材を積層する際に加熱されたロール材の熱可塑性樹脂とストリンガ５に含まれる熱可塑性樹脂とが一体化するため、複数のストリンガ５が一体化された胴体形状の複合材料を成形することができる。なお、本変形例では、断面視が略Ｃ型のストリンガ５を例示したが、断面視がＴ型のストリンガなど他の形態の複合材料を用いてもよい。 According to this modification, since the thermoplastic resin of the roll material heated when laminating the roll material on the stringer 5 and the thermoplastic resin contained in the stringer 5 are integrated, a plurality of stringers 5 are integrated. It is possible to form a composite material having a body shape. In this modification, the stringer 5 having a substantially C-shaped cross-sectional view is illustrated, but a composite material having another form such as a stringer having a T-shaped cross-sectional view may be used.
　以上の説明において、第１ロール成形機構１０，第２ロール成形機構２０，第３ロール成形機構３０，第４ロール成形機構４０は、それぞれロール材を冷却する冷却ローラを有するものとしたが、他の態様であってもよい。例えば、第１ロール成形機構１０，第２ロール成形機構２０，第３ロール成形機構３０，第４ロール成形機構４０の少なくともいずれか、あるいはすべては、冷却ローラを備えていなくてもよい。冷却ローラを備えずとも外気等により十分に冷却することができる場合には、冷却ローラを備えていなくてもよい。 In the above description, the first roll forming mechanism 10, the second roll forming mechanism 20, the third roll forming mechanism 30, and the fourth roll forming mechanism 40 each have a cooling roller for cooling the roll material. It may be the aspect of. For example, at least one or all of the first roll forming mechanism 10, the second roll forming mechanism 20, the third roll forming mechanism 30, and the fourth roll forming mechanism 40 may not be provided with cooling rollers. If the cooling roller can be sufficiently cooled by the outside air or the like without the cooling roller, the cooling roller may not be provided.
　以上の説明において、複合材料である第１～第８ロール材には、熱可塑性のマトリックス樹脂が含まれるものとしたが、他の態様であってもよい。例えば、複合材料である第１～第８ロール材には、熱硬化性のマトリックス樹脂が含まれる変形例としてもよい。この場合、以上の説明で熱可塑性樹脂を融点未満に冷却するために用いた冷却ローラは不要となる。また、複合材料を加熱するヒータは、熱硬化性のマトリックス樹脂を含むロール材を、マトリックス樹脂がある程度軟化する温度（例えば、約８０℃）に加熱すればよい。熱硬化性のマトリックス樹脂を含むロール材は、マンドレル１に巻き付つけられた時点では硬化しない状態で積層される。本変形例の場合、マンドレル１への複数のロール材の積層が完了した後、積層された複合材料をオートクレーブ等の加熱装置にて樹脂硬化温度（例えば、約１８０℃）まで加熱して複合材料を熱硬化させる。 In the above description, the first to eighth roll materials, which are composite materials, are assumed to contain a thermoplastic matrix resin, but other embodiments may be used. For example, the first to eighth roll materials, which are composite materials, may be a modified example in which a thermosetting matrix resin is contained. In this case, the cooling roller used to cool the thermoplastic resin below the melting point in the above description becomes unnecessary. Further, the heater for heating the composite material may heat the roll material containing the thermosetting matrix resin to a temperature at which the matrix resin softens to some extent (for example, about 80 ° C.). The roll material containing the thermosetting matrix resin is laminated in a state where it is not cured when it is wound around the mandrel 1. In the case of this modification, after the lamination of the plurality of roll materials to the mandrel 1 is completed, the laminated composite material is heated to the resin curing temperature (for example, about 180 ° C.) by a heating device such as an autoclave to obtain the composite material. Is thermoset.
　以上の説明において、マンドレル１は、軸線Ｘｍに直交する平面における断面形状が円筒状の回転体であるものとしたが、他の態様であってもよい。マンドレル１は、軸線Ｘｍに直交する平面における断面形状が楕円筒状、あるいは四角筒状等の多角筒状の回転体とする変形例であってもよい。この場合、マンドレル１は、軸線Ｘｍと表面との距離が軸線Ｘｍ回りの周方向の各位置で異なる。そのため、本変形例では、マンドレル１の表面にロール材を巻き付ける加圧ローラに軸線Ｘｍまでの距離を調整する調整機構（図示略）を設ける。調整機構は、マンドレル１が回転する際に加圧ローラがマンドレル１の表面に追従するように加圧ローラと軸線Ｘｍとの距離を調整する。調整機構は、例えば、予め設定されたマンドレル１の表面形状に応じて加圧ローラの回転軸と軸線Ｘｍとの距離を電動モータ（図示略）により調整する。 In the above description, the mandrel 1 is a rotating body having a cylindrical cross-sectional shape in a plane orthogonal to the axis Xm, but other modes may be used. The mandrel 1 may be a modified example in which the cross-sectional shape of the plane orthogonal to the axis Xm is an elliptical cylinder or a polygonal cylinder such as a square cylinder. In this case, in the mandrel 1, the distance between the axis Xm and the surface is different at each position in the circumferential direction around the axis Xm. Therefore, in this modification, an adjusting mechanism (not shown) for adjusting the distance to the axis Xm is provided on the pressure roller that winds the roll material around the surface of the mandrel 1. The adjusting mechanism adjusts the distance between the pressurizing roller and the axis Xm so that the pressurizing roller follows the surface of the mandrel 1 when the mandrel 1 rotates. The adjusting mechanism adjusts, for example, the distance between the rotation axis of the pressurizing roller and the axis Xm by an electric motor (not shown) according to the preset surface shape of the mandrel 1.
　以上で説明した第２実施形態において、マンドレル１の軸線Ｘｍに沿った複数の領域（図５に示すＸｍ１～Ｘｍ０までの領域、Ｘｍ０～Ｘｍ２までの領域）に対してロール材を巻き付ける供給部をそれぞれ複数設けるものであった。第２実施形態では、Ｘｍ１～Ｘｍ０までの領域、およびＸｍ０～Ｘｍ２までの領域のいずれにおいても、各領域に積層される複数種類のロール材の軸線Ｘｍに沿った長さは同一であったが、他の態様であってもよい。例えば、Ｘｍ０～Ｘｍ１までの長さを有するロール材とＸｍ１～Ｘｍ２までの長さを有するロール材とを積層するなど、軸線Ｘｍに沿った長さが異なる複数種類のロール材を積層してもよい。 In the second embodiment described above, the supply unit around which the roll material is wound around a plurality of regions (regions Xm1 to Xm0 and regions Xm0 to Xm2 shown in FIG. 5) along the axis Xm of the mandrel 1 is provided. Multiple pieces were provided for each. In the second embodiment, the lengths of the plurality of types of roll materials laminated in each region along the axis Xm are the same in both the regions Xm1 to Xm0 and the regions Xm0 to Xm2. , Other aspects may be used. For example, even if a plurality of types of roll materials having different lengths along the axis Xm are laminated, such as laminating a roll material having a length of Xm0 to Xm1 and a roll material having a length of Xm1 to Xm2. Good.
