Hereinafter, the metal-resin composite of one embodiment will be described.
As shown in FIGS. 2 to 4, the skeleton member 20 is made of a fiber reinforced resin material on a metal plate member 21 composed of two metal plates 21A and 21B via an adhesive layer 22 which is an adhesive layer. It has a structure in which the fiber reinforced resin member 23 is integrally formed. The skeleton member 20 is a metal resin composite in which a metal plate member 21 is reinforced with carbon fiber reinforced resin (CFRP), and has a cross-sectional hat shape.

The metal plate 21A constituting the metal plate member 21 is formed of a hot-dip galvanized steel plate (SCGA), and the metal plate 21B is formed of a cold-rolled steel plate (SPC). The metal plate member 21 has a structure in which two metal plates 21A and 21B are joined to each other in a state of being arranged in the plate surface direction (that is, a direction orthogonal to the plate thickness direction). Specifically, the metal plate member 21 has a structure in which the ends of the two metal plates 21A and 21B are partially joined by welding in a state of being overlapped in the plate thickness direction.

The fiber reinforced resin member 23 is formed of a carbon fiber reinforced resin containing discontinuous carbon fibers using a thermosetting resin material (epoxy resin material) as a base material.
The adhesive layer 22 is interposed between the portion of the metal plate member 21 including the joint portion 21C to which the ends of the metal plates 21A and 21B are joined and the fiber reinforced resin member 23, and is interposed between the metal plate member 21 and the fiber. The reinforced resin member 23 is adhered. As the resin material constituting the adhesive layer 22, a resin material suitable for bonding the metal plate member 21 and the fiber reinforced resin member 23 is adopted. Specifically, the adhesive layer 22 is made of a thermosetting resin material (epoxy-based resin material).

Here, the skeleton member 20 is molded by a hot press using a hot press device, specifically through an SMC (sheet molding compound) molding method. In the present embodiment, as shown in FIG. 4, the seal member 50 is attached to the joint portion 21C of the metal plate member 21. When the skeleton member 20 is molded by the heat press by the sealing member 50, the synthetic resin material or the adhesive which is the base material of the fiber reinforced resin portion material leaks through the gap between the two metal plates 21A and 21B. It is designed to be suppressed.

Hereinafter, the seal member 50 will be described in detail.
As shown in FIGS. 1, 4 and 5, the seal member 50 has a U-shape extending along the inner surface of the joint portion 21C of the metal plate member 21. Further, the seal member 50 has a substantially U-shaped cross section. Specifically, the seal member 50 has an engaging groove 51 extending in a U shape along the extending direction of the seal member 50. The engaging groove 51 has a shape capable of fitting the end portion of the metal plate 21A.

As shown in FIGS. 1 and 5, one of the pair of wall portions forming the side wall of the engaging groove 51 in the sealing member 50 is substantially the same as the gap between the ends of the two metal plates 21A and 21B. It is a holding portion 52 having a shape. The sandwiching portion 52 has a shape that can be fitted into the gap between the two metal plates 21A and 21B so as to fill the gap.

The sealing member 50 is made of an elastic material (thermoplastic elastomer).
As shown in FIGS. 6 and 7, a plurality of convex portions 53 are arranged on the inner surface of the engaging groove 51 of the seal member 50, specifically, the surface facing the end of the metal plate 21A, so as to cover substantially the entire surface. Is provided. These convex portions 53 form ridges extending from the opening of the engaging groove 51 toward the bottom, and are provided so as to be arranged at equal intervals along the opening end of the engaging groove 51.

As shown by the white arrows in FIG. 5, the seal member 50 is attached to the inner surface side of the metal plate member 21. Specifically, the sandwiching portion 52 of the seal member 50 is inserted into the gap between the two metal plates 21A and 21B, and the end portion of the metal plate 21A is inserted into the engaging groove 51 of the seal member 50. Then, when the end portion of the metal plate 21A abuts on the bottom of the engaging groove 51, the attachment of the seal member 50 to the metal plate member 21 is completed.

As described above, according to the present embodiment, the holding portion 52 of the sealing member 50 is placed in the gap between the two metal plates 21A and 21B until the end of the metal plate 21A abuts on the bottom of the engaging groove 51 of the sealing member 50. The seal member 50 can be arranged at an appropriate position to close the gap between the joints of the two metal plates 21A and 21B through a simple operation such as inserting the metal plates into the metal plates 21A and 21B.

Further, in the present embodiment, a convex portion 53 extending along the attachment direction of the seal member 50 is formed on the surface of the sandwiching portion 52 of the seal member 50, specifically, on the inner surface of the engaging groove 51. Then, the sealing member 50 is attached by elastically deforming and crushing the convex portion 53 on the surface of the holding portion 52 and pushing the holding portion 52 into the gap between the ends of the two metal plates 21A and 21B to fit the sealing member 50. Will be. As a result, the contact surface pressure between the metal plate 21A and the holding portion 52 is increased as compared with the case where the surface of the holding portion 52 of the sealing member 50 is formed in the same shape as the surface of the end portions of the metal plates 21A and 21B. Since the portion to be raised can be reduced, the sealing member 50 can be smoothly attached to the metal plate member 21.

Hereinafter, the structure of the heat press device 30 used for molding the skeleton member 20 will be described.
As shown in FIGS. 8 and 9, the heat press device 30 has a die device 40 composed of a fixed die 41 and a movable die 43. When the mold device 40 is in the mold clamping state shown in FIG. 9, a space extending in a hat shape in cross section, that is, a space in which the skeleton member 20 is molded is formed between the fixed mold 41 and the movable mold 43. ..

A recess 44 having a shape recessed downward is provided on the upper portion of the fixed mold 41. When the skeleton member 20 is molded, the metal plate member 21, the adhesive sheet 22A to be the adhesive layer 22, and the SMC 23A to be the fiber reinforced resin member 23 are set in the recess 44. The SMC23A is made by impregnating discontinuous carbon fibers with a resin paste containing a mixture of a thermosetting resin material, a curing agent, a thickener, an internal mold release agent, a filler, etc., and coating the carbon fibers with a film to form a sheet. It was done. The SMC23A is well handled by heating it under a predetermined temperature condition to thicken it.

The movable mold 43 is arranged so as to be movable in the vertical direction with respect to the fixed mold 41, specifically, in the mold clamping direction (lower side of FIG. 8) and the mold opening direction (upper side of FIG. 9). A protruding portion 45 having a shape protruding downward is provided at the lower portion of the movable mold 43. Further, an annular wall 47 is provided on the outer edge of the lower portion of the movable mold 43 so as to project in an annular shape. A sealing material 48 extending over the entire circumference is attached to the inner peripheral surface of the annular wall 47. When the hot press is executed by the hot press device 30, the die device 40 is clamped by moving the movable die 43 in a direction approaching the fixed die 41 by a hydraulic cylinder (not shown).

As the mold device 40 is tightened, the protruding portion 45 of the movable mold 43 enters the recess 44 of the fixed mold 41, and the inner peripheral surface of the sealing material 48 provided on the annular wall 47 of the movable mold 43. Comes into contact with the outer peripheral surface of the fixed mold 41 over the entire circumference. At this time, the gap between the outer peripheral surface of the fixed mold 41 and the inner peripheral surface of the annular wall 47 of the movable mold 43 is closed by the sealing material 48, and the fixed mold 41 and the movable mold 43 partition the inside of the mold device 40. The inside and outside of the formed space SP are sealed.

The heat press device 30 has a vacuum drawing device 60 for removing gas in the space SP partitioned by the fixed mold 41 and the movable mold 43 inside the mold device 40 prior to the heat press of the skeleton member 20. There is. The evacuation device 60 has a negative pressure tank 61 in which a pressure lower than the atmospheric pressure is accumulated, and a negative pressure pump 62 connected to the negative pressure tank 61. A through hole 63 is formed above the arrangement portion of the sealing material 48 on the annular wall 47 of the movable type 43. The through hole 63 and the negative pressure tank 61 are communicated with each other through the communication passage 64. In the middle of the communication passage 64, an on-off valve 65 for switching between communication of the through hole 63 and the negative pressure tank 61 by the communication passage 64 and blocking of the communication is provided.

The evacuation device 60 operates as follows. Due to the operation of the negative pressure pump 62, the inside of the negative pressure tank 61 becomes a negative pressure (pressure lower than the atmospheric pressure). Then, when the on-off valve 65 is opened, the through hole 63 and the negative pressure tank 61 are communicated with each other through the communication passage 64. Along with this, the gas in the space SP is sucked and removed through the communication passage 64 and the through hole 63, resulting in a low pressure state in which the amount of gas in the space SP is small.

The heat press device 30 has a heating device 70 for heating the die device 40. The heating device 70 has a steam passage 71 formed inside the movable type 43 and a boiler 73 connected to the steam passage 71. High-temperature steam is supplied to the steam passage 71 from the boiler 73. The movable type 43 is heated by the high-temperature steam passing through the inside of the steam passage 71.

Hereinafter, the procedure for forming the skeleton member 20 will be described together with the action.
As shown in FIG. 10, when forming the skeleton member 20, the metal plate member 21 is first formed (step S1). Specifically, the metal plates 21A and 21B are separately press-molded by a separate press device. Then, the metal plate members 21 are formed by partially joining the ends of the metal plates 21A and 21B in a state of being overlapped with each other to integrate the metal plates 21A and 21B.

After that, as shown in FIG. 5, the seal member 50 is attached to the metal plate member 21 (step S2 in FIG. 10). In the present embodiment, the metal plate member 21 to which the seal member 50 is attached in this way is used for heat pressing by the heat pressing device 30.

Then, when the skeleton member 20 is formed by the heat press device 30, the seal member 50 and the metal plate member 21 are first set inside the mold device 40 (step S3). Specifically, as shown in FIG. 8, the mold device 40 is opened, and the metal plate member 21 to which the seal member 50 is attached is placed on the fixed mold 41.

After that, the adhesive sheet 22A and the SMC 23A are set inside the mold apparatus 40 (step S4 in FIG. 10). Specifically, as shown in FIG. 8, the adhesive sheet 22A and the SMC 23A are placed on the metal plate member 21 so as to be arranged in the order of the metal plate member 21, the adhesive sheet 22A, and the SMC 23A from the lower side.

After that, the mold device 40 is mold-fastened to a temporary tightening position before the mold-fastening state shown in FIG. 9 (step S5 in FIG. 10). Specifically, the seal material 48 on the inner surface of the annular wall 47 of the movable mold 43 and the outer peripheral surface of the fixed mold 41 are in contact with each other over the entire circumference, and the lower surface of the movable mold 43 is made of metal. The movable mold 43 is moved downward to a position where it does not abut on the plate member 21. As a result, a predetermined space SP is formed between the fixed mold 41 and the movable mold 43. Then, in this state, the vacuuming device 60 executes a step of sucking out the gas in the space SP (so-called vacuuming). Specifically, the on-off valve 65 is opened for a predetermined time, and the negative pressure tank 61 is connected to the space SP. As a result, the gas in the space SP is evacuated to a low pressure state, so that the subsequent mold clamping of the mold device 40 can be smoothly performed.

After that, the mold device 40 is mold-fastened to the position where it is in the mold-clamping state shown in FIG. 9 (step S6 in FIG. 10). As a result, the skeleton member 20 is formed by the heat press. Specifically, the adhesive sheet 22A is heat-cured to form an adhesive layer 22, and the SMC 23A is stretched to form a predetermined shape and heat-cured to become a fiber-reinforced resin member 23. In this way, the skeleton member 20 as a metal resin composite having the metal plate member 21, the sealing member 50, the adhesive layer 22, and the fiber reinforced resin member 23 is formed.

As shown in FIG. 11, when the mold device 40 is molded, the fiber reinforced resin member 23 is in a state where the lower surface of the metal plate 21B is supported by the fixed mold 41 around the joint portion 21C of the metal plate member 21. The SMC 23A becomes spread between the upper surface of the metal plate 21A and the lower surface of the movable mold 43. Therefore, as shown by the white arrows in FIG. 11, in the joint portion 21C of the metal plate member 21, the pressing pressure by the heat pressing device 30 is applied to the holding portion 52 of the seal member 50 by the two metal plates 21A and 21B. It acts like pinching and crushing. As a result, the contact surface pressure between the upper surface of the holding portion 52 of the sealing member 50 and the lower surface of the metal plate 21A and the contact surface pressure between the lower surface of the holding portion 52 and the upper surface of the metal plate 21B increase.

Therefore, although the press pressure acts on the SMC 23A and the adhesive sheet 22A when the mold device 40 is clamped, the synthetic resin material which is the base material of the SMC 23A and the adhesive constituting the adhesive sheet 22A sandwich the seal member 50. It is possible to prevent unnecessary leakage through the gap between the portion 52 and the metal plate 21A and the gap between the sandwiching portion 52 and the metal plate 21B. As a result, it is possible to suppress the deterioration of the design of the skeleton member 20 due to the protrusion of the adhesive layer 22 and the fiber reinforced resin member 23, and to suppress the shape variation of the fiber reinforced resin member 23 and the adhesive layer 22 after molding. Therefore, it is possible to form a high quality skeleton member 20.

Further, in the present embodiment, a convex portion 53 (see FIG. 6) is formed on the inner surface of the engaging groove 51 of the seal member 50. In the hot pressing by the hot pressing device 30, the convex portion 53 is pressed against the metal plates 21A and 21B by the pressing pressure and is crushed, so that the inner surface of the engaging groove 51 of the sealing member 50 and the outer surface of the metal plate 21A are high. The contact surface pressure makes it adhere to a wide range. Therefore, it is possible to prevent the synthetic resin material and the adhesive from unnecessarily leaking through the gap between the inner surface of the engaging groove 51 of the seal member 50 and the outer surface of the metal plate 21A.

Here, the press-molded metal plates 21A and 21B tend to have lower dimensional accuracy than the resin-molded products. Therefore, in the metal plate member 21 having a structure in which the metal plates 21A and 21B are joined, it is difficult to make the gap between the metal plates 21A and 21B constant in each part of the joint portion 21C, and it is also difficult to close this gap with the seal member. It can be said. In this respect, in the present embodiment, the press pressure by the hot press device 30 acts so as to crush the holding portion 52 of the seal member 50 in a state of being sandwiched between the ends of the two metal plates 21A and 21B. Therefore, the gap between the ends of the two metal plates 21A and 21B can be accurately filled by the sandwiching portion 52 of the seal member 50.

Further, in the present embodiment, the seal member 50 is attached to the inner surface side of the metal plate member 21. As a result, the opening on the side where the SMC 23A and the adhesive sheet 22A are arranged in the gap between the two metal plates 21A and 21B is closed by the seal member 50. Therefore, it is possible to prevent unnecessary entry of the synthetic resin material which is the base material of the SMC 23A and the adhesive constituting the adhesive sheet 22A into the gap between the two metal plates 21A and 21B. As a result, it is possible to suppress the shape variation of the fiber reinforced resin member 23 and the adhesive layer 22 after molding. Moreover, in the present embodiment, the pressing pressure of the heat pressing device 30 acts to push the holding portion 52 of the sealing member 50 into the gap between the two metal plates 21A and 21B via the SMC 23A and the adhesive sheet 22A. As a result, the seal member 50 is held at a position where the end of the metal plate 21A abuts on the bottom of the engagement groove 51 of the seal member 50, so that the displacement of the seal member 50 can be suppressed. ..

After the mold device 40 is put into the mold tightening state in this way (step S6 in FIG. 10), the mold device 40 is put into the mold open state, and the skeleton member 20 is taken out from the inside of the mold device 40. (Step S7). As described above, the skeleton member 20 of the present embodiment is formed by hot pressing with the hot pressing device 30.

According to this embodiment, the effects described below can be obtained.
(1) The skeleton member 20 is provided with a seal member 50 having a holding portion 52 sandwiched between the ends of the two metal plates 21A and 21B and an engaging groove 51 engaged with the ends of the metal plates 21A. , The metal plate member 21 is provided so as to extend along the joint portion 21C. As a result, it is possible to suppress the deterioration of the design of the skeleton member 20 and suppress the shape variation of the fiber reinforced resin member 23 and the adhesive layer 22 after molding, so that the skeleton member 20 of high quality can be formed. it can.

(2) An engaging groove 51 having a shape in which the end portion of the metal plate 21A fits into the sealing member 50 is formed. Therefore, even when a force that causes the holding portion 52 of the seal member 50 to enter the gap between the two metal plates 21A and 21B acts, the end portion of the metal plate 21A is the bottom of the engaging groove 51 of the seal member 50. The movement of the seal member 50 is restricted by hitting the seal member 50. As a result, it is possible to prevent the entire seal member 50 from being fitted between the two metal plates 21A and 21B, so that the seal member 50 can be easily arranged at an appropriate position. ..

(3) The engaging groove 51 of the seal member 50 is engaged with the end of the metal plate 21A arranged on the fiber reinforced resin member 23 side of the ends of the two metal plates 21A and 21B. As a result, it is possible to prevent unnecessary entry of the synthetic resin material which is the base material of SMC23A and the adhesive constituting the adhesive sheet 22A into the gap between the two metal plates 21A and 21B, so that the fiber is reinforced after molding. It is possible to suppress the shape variation of the resin member 23 and the adhesive layer 22.

(4) A convex portion 53 having a shape protruding in an inelastically deformed state is provided on the inner surface of the engaging groove 51 of the seal member 50. As a result, the contact surface pressure between the metal plate 21A and the holding portion 52 is increased as compared with the case where the surface of the holding portion 52 of the sealing member 50 is formed in the same shape as the surface of the end portions of the metal plates 21A and 21B. Since the portion to be raised can be reduced, the sealing member 50 can be smoothly attached to the metal plate member 21.

The above embodiment can be modified and implemented as follows. The above embodiment and the following modified examples can be implemented in combination with each other within a technically consistent range.

The shape of the convex portion 53 formed on the inner surface of the engaging groove 51 can be arbitrarily changed. For example, it is possible to provide a convex portion on the inner surface of the engaging groove 51 so as to form a dot.
Even if the convex portion 53 formed on one of the pair of inner side surfaces of the engagement groove 51 of the seal member 50 is omitted, or the convex portion 53 formed on both of the pair of inner side surfaces is omitted. Good. In addition, it is also possible to provide a convex portion having a shape protruding in an inelastically deformed state on the surface of the sandwiching portion 52 of the seal member 50 facing the metal plate 21B.

-Instead of providing the convex portion 53 on the inner surface of the engaging groove 51 of the seal member 50, an inner surface concave portion may be provided. Even with the same configuration, the contact surface between the metal plate 21A and the holding portion 52 is compared with the case where the surface of the holding portion 52 of the sealing member 50 is formed in the same shape as the surface of the end portions of the metal plates 21A and 21B. The part where the pressure becomes high can be reduced.

As shown in FIG. 12, a ridge portion 54, which is a convex portion that extends continuously in the extending direction of the seal member 50, may be provided on the inner surface of the engagement groove 51 of the seal member 50. When the convex portion 53 is provided on the inner surface of the engaging groove 51 of the seal member 50, the amount of protrusion of the ridge portion 54 from the inner side surface may be equal to or greater than the amount of protrusion of the convex portion 53. preferable. According to the above configuration, the seal member 50 (protruding portion 54) is continuously formed in the engagement groove 51 of the seal member 50 over the entire length in the extending direction, regardless of the shape of the convex portion 53 or the inner surface concave portion. The tip) and the end of the metal plate 21A can be brought into close contact with each other. Therefore, it is possible to prevent the synthetic resin material which is the base material of the SMC 23A and the adhesive constituting the adhesive sheet 22A from unnecessarily leaking through the gap between the holding portion 52 of the sealing member 50 and the metal plate 21A.

As an example shown in FIG. 13, the end of the metal plate 21B arranged on the side of the ends of the two metal plates 21A and 21B far from the fiber reinforced resin member 23 is the engagement groove of the seal member 50. The seal member 50 may be provided at the joint portion 21C of the metal plate member 21 in a manner of fitting into the 51. With the same configuration, it is possible to obtain an effect similar to the effects described in (1), (2) and (4) above.

The shape of the engaging portion that engages with one of the ends of the two metal plates 21A and 21B is not limited to the groove shape into which the same end is fitted, and can be changed to any shape. For example, as shown in FIG. 14, as the sealing member 80, the holding portion 52 sandwiched between the two metal plates 21A and 21B and the abutting wall portion 81 to which one of the two metal plates 21A and 21B abuts come into contact with each other. An L-shaped cross section can be adopted.

When molding the skeleton member 20, the movable mold 43 may be continuously moved from the mold open state to the mold tightening state without temporarily stopping the movement of the movable mold 43.

-As a configuration for heating the movable type 43, instead of providing the boiler 73 and the steam passage 71, an oil passage for supplying high temperature oil is provided inside the movable type 43, or an electric heater is provided in the movable type 43. You may attach it.

-The skeleton member according to the above embodiment can also be applied to a skeleton member molded by a molding method other than the SMC molding method. Examples of such a molding method include a PCM (prepreg compression molding) molding method and an RTM (resin transfer molding) molding method.

-As the resin material constituting the adhesive layer 22, a thermosetting resin material (for example, urethane-based resin material or acrylic-based resin material) other than the epoxy-based resin material can be adopted. In addition, a thermoplastic resin material can be adopted as the resin material constituting the adhesive layer 22, for example, a hot melt adhesive is adopted as the adhesive constituting the adhesive layer 22.

-As the base material of the fiber reinforced resin member 23, a thermosetting resin material (for example, unsaturated polyester resin or vinyl ester resin) other than the epoxy resin material can be adopted.

-The skeleton member according to the above embodiment can also be applied to a skeleton member formed by hot-pressing a fiber-reinforced resin material whose base material is a thermoplastic resin material onto a metal plate member. Further, the skeleton member according to the above embodiment is formed by hot-pressing a fiber-reinforced resin material reinforced with a fiber material other than discontinuous carbon fibers (for example, continuous carbon fiber, glass fiber, aramid fiber) onto a metal plate member. It can also be applied to skeletal members. In addition, the skeleton member according to the above embodiment can also be applied to a skeleton member formed by hot-pressing a fiber reinforced resin material onto a metal plate member made of a metal plate (for example, an aluminum plate) other than a steel plate.

The skeleton member according to the above embodiment can be applied to a skeleton member having an arbitrary shape other than the hat shape, such as a skeleton member having a U-shaped cross section and a skeleton member having an L-shaped cross section.
-The skeleton member according to the above embodiment can also be applied to a skeleton member having a structure in which a fiber reinforced resin member is attached to the metal plate member via an adhesive applied to the surface of the metal plate member.
