Description of the Related Art Conventionally, it has been required to reduce the weight of a structure represented by a robot arm or the like, and an aluminum alloy is often used as the lightweight structure. Since aluminum alloy has a lower elastic modulus and yield point than steel and the like, when it is used in a structure to which a high load is applied, it is easily deformed. Further, it is difficult to realize a structure made of an aluminum alloy in order to further reduce the weight or increase the rigidity of the structure. Therefore, for a structural material used under such conditions, a carbon fiber reinforced resin (CFR) having a higher elastic modulus and yield point and a smaller specific gravity than an aluminum alloy is used.
An aluminum material reinforced with P) is used. that time,
A so-called hybrid structure in which CFRP is fixed on the surface of the base material of the structure is adopted.

められている。The method of adhering CFRP to the base material is suitable for joining a wide range of dissimilar materials, but when a large load is applied, it is caused by the difference in elastic modulus between dissimilar materials. As a result, shear stress is concentrated on the adhesive end and peeling may occur. On the other hand, in the one described in the above publication,
Although it is possible to improve the adhesive strength at the end portions, there is still a possibility that peeling may occur from the end portions when the load applied to the structure increases. In particular, as the weight and the rigidity of the structural members are further advanced, improvement of this method of pressing the end portion with the pressing plate is required.

Even if a tensile load or a bending load is applied to the structure 70, the CFRP of the reinforcing material 10 does not peel even under a high load condition because the reinforcing material 10 is mechanically bonded to the base material 20. In order to increase the rigidity with respect to the tensile load, it is preferable that the reinforcing material 10 is adhered to the surface on which the tensile load acts so that the tensile direction and the orientation direction of the carbon fibers of the reinforcing material 10 coincide with each other.

止出来る。Further, since the holding plates 40 and 50 are made of a material or surface treatment that has good adhesiveness to CFRP, even if the base material 20 and the reinforcing material 10 are not well adhered to each other,
It is possible to obtain stable adhesive strength. That is, as long as the joint between the holding plate 40 and the reinforcing material 10 is strong, the base material 20
The rigidity of the structure can be increased regardless of the material of the base material and the surface treatment coating of the base material 20. Since the holding plate 50 is attached to the reinforcing material 10, the shear stress generated at the adhesive interface between the holding plate 50 and the reinforcing material 10 can be dispersed, and the CFRP can be prevented from peeling.

Although the holding plate 50 is bonded to 0, the CFRP can be prevented from peeling off only by the adhesive force between the holding plate 40 and the reinforcing material 10 when the applied load is small, and thus the holding plate 50 becomes unnecessary. Since the protrusion 41 is formed on the holding plate 40 and the taper 11 is formed on the reinforcing material 10, the shear stress at the adhesive interface can be reduced.
These are also unnecessary when the load applied to the structure 70 is small.

不要となる。In this embodiment, since the step 42 is formed on the holding plate 40, the adhesion with the pressing plate 30 is improved. The holding plate 30 increases the adhesion area with the end portion of the reinforcing material 10. This makes it difficult for the end portion of the reinforcing material 10 to separate from the base material 20 made of aluminum alloy, and the rigidity of the structure is improved. Since the bolt 60 is tightened from the upper surface of the holding plate 30, the vertical stress acting on the end portion of the reinforcing material 10 can be reduced. Since the vertical stress is small except under a high load, the peeling can be prevented only by the adhesive force when the load is small, and the bolt 60 becomes unnecessary.

It becomes possible to prevent the adhesive peeling between them.
